HScope material repository
Hello
In the HS402 oscilloscope with firmware version 1.5, crosstalk is created between the channels.
If both channels are enabled in the app, part of the signal connected to one channel is visible on the other channel.
The problem does not arise if only one channel is enabled in the application.
At first I thought I had a damaged BlackPill board, but I checked it on another board and the problem also appears.
I tested connecting the input signal through a divider and directly to ports PA3, PA5.
The problem still persists so it is not related to a divider or GND offset.
I also made the HS102 oscilloscope and there is no problem there.

CH-1 - connected 1kHz square signal
CH-2 - nothing connected or GND
Category: nice to have / improvement.
It struck me that the samples/s scale, or the Hz scale, does not follow the standard steps that are accustomed with oscilloscopes: 1,2,5,10,20,50, etc.. Here and there in-between values are used, and here and there the step suddenly is quite large. Would it be possible to change the time scale to the standard 1,2,5 step sequence?
Even nicer would be to have a standard 1,2,5 time/div scale in stead of a samples/s or Hz scale. Time/div is what everyone is used to with oscilloscopes. The app can calculate and display the samples/s it is going to use with the selected time/div setting. It could be an option that the user can still change the sample/s setting.
For instance the OpenHantek6022 Linux/Mac/Windows app works like this ... the user selects a time/div, the app calculates samples/s, the user can still change this if wanted.
Hi. I have the paid full vesion with automotive module. I bought an Android pad with OTG compatibility. (Tested with OTG check app). I also bought OTG compatible USB C connector. I launch Hscope but it will only show DEMO mode. It says device not connected. I have the Hantek powered separately. Are there any drivers I need to install alongside the Hscope app?
Regards
The polarity of the 1000uF cap is different between the schematic and the proto board layouts in the HS101_Schematics.diy file.
Hi there,
is the 1022i supported? The list has the vds1022 only.
Thanks,
i use STM32F401 and flash with HS402_V1.6_F401.bin，when connect to my phone（LG V50 with Android 11），it Cannot detect the HS402 Oscilloscope， I Check my phone with a USB disk ，the OTG work ok。can you tell me what‘s problem？thank！[email protected]
The title (hopefully) says it all! Has anyone tried to run Hscope under Chrome?
First of all, thank you for a great project.
Is it possible to have a custom brightness level setting instead of just a max level "High Brightness" setting?
I find myself needing to manually adjust the brightness every time I use the application, somehow it's darker than the other apps and "High Brightness" setting makes it way too bright for my eyes.
Thanks.
Please make proper schematics with connection dots. Current schemes is confusing and forcing me to figure out correct wiring.
Using an ONN 100011886 tablet, the new version of HSCOPE, updated from the Play Store on Sept 4, 2021, crashes when attempting to change probe settings in setup. After crash, rerunning the app shows that the change requested in the probe setup was made, just crashes the app and requires rerun. Problem noted in demo, and online 6022BE modes.
When the 2 channels has very different ranges the smaller channel is not visible respect the other channel. Need to add a function to change the scales in the way to have the 2 channels comparable on the screen.
When I save Oscilloscope data, it saves as a zip file with a nice picture and hxml data. Unfortunately, I can not do anything with the xhml file. How can I convert that data to CSV?
First of all, I am sorry for opening an issue entry but actually I could not find any other practical method.
Dear martinloren, thank you for your wonderful work. It would be very practical using STM32 as a DSO device. Also, it would be very very nice a four-channel version of HS10x series.
I have a request for HS104 (four-channel version).
Thanks in advance

I am using OWON VDS1022 and realme 8 together to use HScope. On using the probe at x10, the results are apearing to be very jagged. I tired confirming if this is a hardware or software problem, and confirmed that this is surely a problem with Hscope.
Sine waves are looking pretty awful at x10 probe
Sometimes when change voltage level or AC/DC selector the oscilloscope do not apply the setting. Stoping and restwrting the acquisition allow to apply the new settings.
Add some features such as mathematical operations (add, substrate, etc) and vertical waves invert mode.
Seems the schematic files cannot be opened with DIY Layout Creator version 4.7.0 running under Windows 10 Pro which has been proven to work with some version 4 example files.

Add an option in the Settings to avoid the sleep mode.
Hi All,
I have a Hantek 6022BL USB scope/logic analyser. I would like to use this device to perform long term (like 24 hours) voltage monitoring with a low sample rate (like 1 Hz (Sa/s) or less).
Unfortunately, neither OpenHantek nor PulseView seems to offer this functionality for the 6022BL. I would like to explore whether the Data Logging feature within HScope could be used to perform this function please?
Thanks for any support.
Shane,
Add the IP scan in wifi mode to automatically detect iDSO1070 on the network.
just seen a video about measure current on a car, what probe did you use ? is that diy one ?
i'm thinking about measure through resistor but its not isolated i need a safety approach like hall effect or a coil, and how to do that ? i'm not buying current probe and need a diy one.
It may be useful to add a save/load settings feature like presets. It may be an optional feature to be enabled in the Settings.
Hi @martinloren,
I get "Device not connected" on my phone Xiaomi A1. Maybe I'm doing something wrong:
When I connect the stm32 on a windows machine, no device get recognised...
Did I miss something or is there a problem with my phone?
How can I debug this?
Thanks!
Add an option in the Settings to avoid the sleep mode.
Make a better estimation of the signal main frequency. Consider an option to provide accurate calculation on user click.
I am using a Lenovo A3500FL/Android 7.1 with HScope. HScope detects the LHT00SU1 ok, but only displays a straight line, Ch1 [pk-pk 0mV DC, 8,91V].
I have tested HScope on some other devices, Huawei Mediapad/Android 4.4, Motorola G7/Android 10 with the same result.
The LHT00SU1 works ok with PulseView (fx2lafw) on the same devices and on a PC.
Second scale for second channel would be more visible on the right, together with its own unit.
On an HS102 Pro, after turning on channel 2 to DC mode and then disconnecting the USB and reconnecting, the app will erroneously show DC mode on channel 2 when it is actually in AC mode. Switching channel 2 off and then back to DC mode will fix the issue until the next disconnect and
reconnect.
This is confirmed by using a volt meter and checking pin PB13 is at 0 volts after reconnecting.
Channel 1 does not display this improper behavior.
Add shortcuts, specially for only keyboard and mouse interface operations.

I'm trying to get additional button on hs402 wifi connection, any chance to make this work ?
Need to add a tool to create labels over the graph in Aumotive Module. User should be able to set the number of labels, spacing and labels content.
Hello martinloren
big thanks for this project :)
im beginner and have some small questions
in Materials for HS101 PRO i see - Voltage Ranges: ±15V, ±7.5V, ±3.25V, ±1.5V, ±470V
how ±470V is works?, it need additional divider or i can connect this big voltage to HS101 PRO input, it is not dangerous?
i have standart oscilloscipe probe with selectable division 1:1 and 1:10, and another high voltage probe 1:100 up for 1500 volts, may i use it with HS101 PRO?
thank you
I have installed Hscope on Nox on a windows 10 tablet but it doesn't recognise my hantek 1008C it only opens in demo mode, but its a registered version. I have tried using direct USB into tablet and also with converter lead from USB to mini USB. It works fine on tablet with hantek software but not through Nox with HScope software. Am I missing something ?
Stats follow the position on the wave, if the values changes too fast the numbers are not easy to read. Need to improve the visualization.
Save the probe settings on file in some common folder on the android device or on Cloud, so to be able to copy these settings data and do not loose with the app updates or device change.
I am using the licensed version of HScope.
But the firmware HS101_BLT_V10.1.bin does not work for me, the version HS101_BTL_v9.bin works fine.
What could be the problem?
Will there be version 10.2 for bluetooth?
Hi, I wonder why you use IC AMS1117-1.2v in 5v Best Module.
The output pin is not used, is 1.2v important or can it be replaced with a 1.8v or 3.3v?
I was going to build the HS101 Pro and noticed in the HScope app and on the firmware since version 8 there is support for HS102 Pro.
I'm unable to locate the schematics for a HS102 Pro on Github or your HS10X website. Can you tell me if the feature of HS102 Pro is available?
Thanks,
Add Time/Division selection instead of sampling rate.
hy
how i can transfer my license from phone to tablet?
regards
Zero Level Calibration
The pop up window says:
2) Sconnect the probe or shortcut to GND. This should probably read 'Disconnect'. Maybe it is even better to leave disconnect out and always advise to connect to GND.
--> Updated in V.137
Positioning channel 2: green arrow is hidden
When activating channel 2, the green arrow to change position is hidden behind the sidebar tab. It is hard to get hold of it. See image ‘Channel2_Positioning_1’.
Possible solution:
Move the sidebar tab further to the top.
Or, don’t have a sidebar tab at all, sidebar is opened and closed by swiping.
--> Channel 2 arrow moved on left side.
Positioning channel 2: can’t grab the green arrow when it is at the bottom
I somehow managed to get the situation like in image ‘Channel2_Positioning_2’.
I was not able to grab the green arrow to move the signal … adding a purple cursor has priority.
--> New priority: Trigger, Channel 2, Cursors
Single trigger & Unlock: looks at level in stead of edge
See images ‘Trigger1’ and ‘Trigger2’. Single trigger is activated, channel2, upward edge. I hoped that pressing 'Unlock' would start display when the signal has its first upward edge. What happens however is when the signal already is higher than the trigger level, display starts immediately … rendering only part of the first pulse.
Possible solution:
Looks like acquisition is activated by: IF sample > trigger THEN start.
Better would be: IF previous_sample <= trigger AND current_sample > trigger THEN start.
It also leads to the display of signal values that were not there … which is even worse when Phosphor mode is switched on … see next point.
--> Problem of dirty samples at the beginning in 6022 devices should have been fixed from V.136 BETA. Still exist in Experimental Mode.
Trigger Unlock > scale changes, strange phosphor effects
If Single trigger & Unlock is used, then initially the scale changes and shortly after the scale goes to the set values. This leads to a short screen flicker after Unlock. Moreover … when Phosphor effect is active, sometimes an artifact stays visible in this situation. See image Phosphor_Unlock_Scale.
--> Updated in V.137. Scale Y now change just on input voltage change.
Pan & zoom
When the 'Scope' button is switched off and acquisition stops, initially the display can not be dragged vertically, only horizontally. Only after a two finger pinch, or after tapping the 'Zoom to Fit' icon, the screen can be dragged vertically.
--> Cannot be replicated, provide sequence of buttons used to arrive to this condition. Probably the Y screen is already zoomed to maximum.
Scale on the voltage meter is misaligned.
See image ‘Voltage_Scale_Misaligned’.
--> Need to test again.
Demo signals are not static
The demo signals change when time scale or amplitude scale is changed. This is rather unexpected and trying out the effects of scale changes in demo mode is rather impossible.
--> Implemented in V.137. Sample signal frequency switch to lower value in Roll Mode.
NICE TO HAVE
Horizontal (voltage) cursors.
Channel1 arrow
Only channel2 has an arrow cursor. It would be nice if channel1 also has an arrow.
Trigger adjustment to a specific value
The red trigger cursor arrow is hard to position at an exact value. Say I want to set it at exactly 2.0V, or later back to 0.0V … it is very hard to do.
Possible solutions:
The same holds for the time scale cursors … it is difficult to position them at an exact sample.
Display of the sample ranges / frequencies
The character used for kilo is k … non capital.
A space between the number and the units will improve readability: 10 kHz in stead of 10KHz.
--> Updated in V.137 for all units
Mearurement results display position fluctuations
When the Measurements button is pressed the measurement results show in the neighborhood of the actual signal. While this can be handy to distinguish them with 2 channels displayed, the backside is that their position fluctuates when the signal fluctuates. An alternative cold be to have two boxes, one yellowish, one greenish, stable positioned, with the measurement results displayed in them.
Settings page.
When tapping settings, why not by default start in the General Settings in stead of Info?
The number of chapters is short enough to all be on the top level, in stead of having paragraphs under the Settings chapter.
The font could be larger ... I have a hard time to tap the correct item on my tablet.
--> Updated in V.137
Zoom resets after tapping 'Scope' button.
Starting and stopping acquisition by tapping the 'Scope' button changes the display back to 'no zoom', also after the user has just zoomed in manually, or has tapped the 'Zoom to Fit' icon. Can it stay at the current zoom setting when tapping 'Scope'?
--> Updated in V.137, Y Zoom do not change any more, just X axis is adjusted to center the trigger point, and to show WIDTH/4.
'Zoom to Fit' icon only zooms vertical
When tapping the 'Zoom to Fit' icon, only the vertical, voltage, zoom is applied. Why not also change the horizontal zoom such that, at least for a repetitious signal where a frequency can be measured, 3 periods are in view and T0 is in the middle?
Actually ... why not always automatically zoom to fit? Unless the user has zoomed by hand to his liking, then keep that zoom setting.
--> In most of cases you want to navigate on a custom zoom in X and enlarge to fit just along Y. Fit according X has no sense since you can have 2 signals at difference frequency, so which one you would like to fit automatically?
'Auto' button.
The 2 channels have an auto scale button. Could there also be an overall 'Auto' button, after which Hscope analyzes the incoming signal and automatically selects the best time scale and voltage scale?
--> This is a cool feature to consider...
