DHOTools for the Sparrow Extended UI and the RIGOL DHO 800/900 series oscilloscopes

[mriscoc]

DHOTools is an application designed to expand the capabilities of RIGOL oscilloscopes of the DHO800 and DHO900 series. It allows you to perform advanced analyses, such as FFT averaging, long-term data logging, and arbitrary zoom of a signal, from a PC with Windows or Linux, directly on the oscilloscope or from your mobile device (cell phone or tablet) via a network connection.

How to install in the DHO

Connect the Oscilloscope to the network and check its current IP. Copy the apk file to android-sdk\platform-tools on your PC, then execute this command inside of the platform-tools folder:

> adb connect [oscilloscope IP]:55555
connected to [oscilloscope IP]:55555

Install the utility using:

> adb install -r -g DHOTools_0.3.4.apk
Performing Streamed Install
Success

How to uninstall:

> adb uninstall org.mriscoc.dhotools

Start the application from the launcher or by using adb:

> adb shell monkey -p org.mriscoc.dhotools -c android.intent.category.LAUNCHER 1
Events injected: 1
## Network stats: elapsed time=36ms (0ms mobile, 0ms wifi, 36ms not connected)

DHOtools can be also launched from the DHOActions panel

Note

This version only works if you have previously installed the Sparrow Extended update.

Connecting a DGE20XX to a DHO800/900 series Rigol oscilloscopes

Note

Due to poor performance and limited usability on Android versions, it is advisable to run the frequency response page of the DHOTools remotely on a PC.

The firmware built for the DHO devices does not include the correct library to enable a DGE20XX device to connect via USB. Therefore, a library has been compiled for this platform and needs to be installed in a system folder.
Decompress the library from the ZIP file:

libusb-1.0.so.zip

Install this library in the DHO by using ADB:

  adb root
  adb remount
  adb push libusb-1.0.so /system/lib64/
  adb shell chmod 644 /system/lib64/libusb-1.0.so

Connect the DGE20XX to the USB port and reboot the DHO. Once the device has rebooted, change the permissions:

  adb shell su -c "chmod 666 /dev/bus/usb/*/*"

To avoid changing the permissions with each reboot, add the 'chmod' command to the startup script at '/Rigol/shell/start_rigol_app.sh'. Then install the DHOTools APK. The first launch will abort due to the time it takes for the application to decompress.

Hi my name is Rense.
I have a DHO924S (and a SDS804X HD) to play with.
Thanks for helping me out with the zone-edge app.

Four wishes:
Upon connecting to the data server, check which (first) math channel the FFT is displayed on and use that as the base for displaying it.
-could the app intercept the 'quick' button from the scope and execute that action?
-make it possible to use a logarithmic axis
-a possibility to view frequency and the phase information of a signal.

Original plot

This is the result for semi logarithmic X axis

[mriscoc]

So, at low frequencies there is a loss of resolution. It is acceptable for you?

[RAPosthumus]

First reaction: yes but we should quantify the loss. Op do 11 apr. 2024 18:39 schreef Miguel Risco-Castillo < ***@***.***>:

I added button to enable xlog scale, I will release the new apk soon.

[RAPosthumus]

Awesome, thanks for the update! Will test this in the weekend Op do 18 apr. 2024 19:27 schreef Miguel Risco-Castillo < ***@***.***>:

Thank you for your suggestions. I'm making some improvements to the tool

Hello.

I have installed the Windows version, but it doesn’t connect and I don’t know how to specify the DHO’s IP address. Also, when I launch the APK on the DHO, it opens in full screen and I don’t know how to make it use only half of the screen like in the examples you show.

[mriscoc]

DHOTools for Windows will automatically detect any DHO connected to the same subnetwork. You don't need to specify an IP address; just make sure that the DHO is connected to the network and has an IP address before launching DHOTools.
To open the DHOTools APK on Android in split-screen mode, you need an application that can enable this feature. I use Zonelauncher (https://play.google.com/store/apps/details?id=com.bialy.zonelauncher) in my examples, but any other similar application can be used.

[generalasde]

The DHO and the PC are on the same subnet, and I can connect using both DHOVision and the web server. I’m not sure what could be causing the issue that prevents me from connecting.

[mriscoc]

Ok, I confirm the bug in the 0.3.4 version of DHOTools, it is looking for a device in a fixed ip address

[mriscoc]

Please try with this version: https://github.com/mriscoc/Sparrow-Extended-GUI-for-RIGOL-DHO800_DHO900/releases/download/DHOTools/DHOTools_setup_0.3.5_WINx64.exe

[generalasde]

Thank you for the quick response. It works perfectly.

DHOTools for Windows, updated to 0.3.6:

• THD button in the FFT screen.
