Hi @Kabron I've corrected the html special chars. Thank you for the observation.

Hi @Leo_W

Hi @David Aurora

Hi @David Aurora It will be added to the next version. Thank you for your post.

Hi @Arty All the rails/IOs are referenced to GND of the device. The power supply of the device may be isolated/floating but the GND connects to the computer via the USB cable which can have earth GND!

Hi @Leo_W Having only 1 channel of 2 checked (or 1 of 4 or 2 of 4) should reuse the buffer of the other channel(s) so the available capture buffer size doubles (or quadruples). Unfortunately when one of the two channels is disabled the "firmware" stores each sample twice. This is visible if you zoom in further. It will be fixed in the next version. Sorry for these bugs. The Eclypse-Zmod-WF support was internally used for several years. Now, before going to public I've added many new features to it but it looks like I haven't tested thoroughly enough...

Hi @Leo_W The Zmod-Scope has two gain/input range steps <=200mV/div (2V pk2pk) and 50Vpk2pk, giving ~0.13mV and ~3.2mV resolution for 14bit resolution ADC Are you using BNC cable?

Hi @proyo See the following posts and example:

Hi @lokobob99 To see the peaks in the FFT plot the top frequency ( sample rate/2 ) should be about 5-20 higher than the signal or you can only use the interested part of the FFT. Like here 1MHz signal with 10M top (20MHz rate), see: AnalogIn_FFT.py

Hi @Leo_W In combination of B-ADC and A-DAC the Scope gain control was not working but it is fixed in the latest version:

Hi @chip Unfortunately the ADP5250 is Windows only. https://digilent.com/shop/analog-discovery-pro-adp5250-all-in-one-1gs-s-100mhz-mixed-signal-oscilloscope-function-generator-power-supply-and-dmm/

Hi @martinaviola See the following post:

Hi @crile You can find a C# wrapper in the WF SDK/ cs/ dwf.cs, add this to your project. The examples are under py/ and some under c/ which can be used as pseudocode for examples for other languages.

Hi @darth458 The AUX supply is stopped when the USB voltage drops, see IC48 supply is from VBUS: https://digilent.com/reference/test-and-measurement/analog-discovery-2/hardware-design-guide#usb_power_control You could use a powered USB hub to supply and configure the device. Set the "On Close" option to Continue the outputs to work after application close or disconnect the computer from the hub.

Hi @Alessandro Yes and you can use FDwfAnalogInChannelAttenuationSet to specify the amplification (1/att) so the read voltage data is scaled correctly.

Hi @LJH See the following: ex1.py (changed to sine to be easier to verify) If you are capturing less than 32Ki samples/channel you can use single capture mode. You could use up to 32Ki samples for analog-out custom for higher resolution signal. I recommend using the latest version sine beside other things it fixes some related to ADP3000 recording.

The AD5250 does not support recording, this button should have been disabled.

Hi @Leo_W Which Zmods are you using and in which connectors ?

Hi @PhilipJ It is already available:

Hi @Leo_W Can you hear the relays clicking when you change between 200mV and 500mV ? The switch between AC and DC should be also click. If not probably the relay on C1 low/high range is not working, LR <= 200mV/div (2V pk2pk) and HR above this.

Hi @arnavguptagenerac Reduce the sample rate, like to 160kHz as it is in your WaveForms app screenshot, to get have 5.12ms 8192/160k dwf.FDwfAnalogInFrequencySet(hdwf, c_double(160000.0))

Hi @Anthocyanina Just increase the height of the Bus or the interpreter you are using, specify format, skip bits if needed... Alternatively in the Script tool you can add plots or transfer the Logic Analyzer data to Scope channel data or Wavegen...

Hi @Mandar Most of the TM devices Analog Discovery 2, Digital Discovery, ADP3450/3250... except ADP5250 offer I2C spying. This is a lateral feature and it does not support high transfer bandwidths but the Logic Analyzer instrument with triggering can be used to capture interested events.

Szia @Ákos I've forwarded your question to the logistics team to see if (at least) the replaced probes are tested. To make sure, you could also ask Mouser if the probes are tested with AD2+BNC. It is expected, the BNC adapter 2nd scope input has about 3pF higher capacitance than the 1st one.

Hi @JohnC124 The AD2 has two input ranges (gains), with 1X 50/5Vpk2pk, 0.1X 5/0.5V, with 0.01X 0.5/0.05V, with 10X 500/50V... With 1X and 5V range the scope input is in low range but with 0.1X and 5V in high range, so the resolution will be about the same. See the Trace info on bottom left of your plot area. To have the same input range/gain after changing the attenuation adjust the range option to the lower or higher value.
