Hi @longboard Yes, when the histogram resolution is lower than the ADC resolution there will be probably more samples in hist steps, increasing the % The bar option is available in newer sw version:

Hi @longboard The histogram Y axis represents the percentage of samples within value ranges reported to the total visible number of samples. The histogram width is the full ADC channel range and the default value range is the ADC resolution.

Hi @tropical_95 See the SDK/API manual and examples/ py/ : AnalogOut_Play.py, AnalogOutIn_PlayRecord.py, AnalogOutIn_PlayRecordStereo.py, AnalogOutIn_RecordPlay.py, AnalogIn_Record.py ...

Hi @JeromeBoateng 100R, see: https://digilent.com/reference/test-and-measurement/digital-discovery/reference-manual#accessories https://digilent.com/reference/_media/reference/test-and-measurement/digital-discovery/250-104_dp_2.54_3.pdf

Hi @marle12 The 0/4V signal can be connected to AD2 DIOs and use a series resistor to limit the current. The input logic threshold is about 1.5V or 0.5V with 5/7th configurations. The Pattern generator ROM logic can be used for IO purpose. Like here DIO 0 input and DIO 1 output.

Hi @tropical_95 The Measurements in Scope are calculated on the visible area. Custom measurement or Script can be used for other purposes.

Hi @tropical_95 Use the trigger options. Like here Wavegen is set to trigger on Scope and this to record without trigger. Start Wavegen then Scope and wavegen will wait for the scope to be started. The Scope trigger position can be set to 0%, rate, samples and time adjusted under the Config button.

Hi @Andrei_ There is no decoder implemented for such protocol but you could use Bus or Custom decoder in the Logic Analyzer.

@Cristian.Fatu

Hi @tropical_95 Such intermittent errors could be caused by contact issue on the USB lines (data+/- or supply/gnd). Try using other cable, port, hub...

Hi @tropical_95 Probably there is a contact issue. Try using the original USB cable or other microUSB cables you have at hand. Also make sure the VCP is unchecked, see:

Hi @mnorth The record mode is intended for long captures, streaming samples and the frequency can be up to about 1-2MHz. If you want to capture only up to 8/16Ki samples you can use the normal (single) capture mode at up to 100MHz.

Hi @Buzz The scope inputs are differential but not floating so these have some common mode limitations, see: https://digilent.com/reference/test-and-measurement/analog-discovery-2/hardware-design-guide#scope_signal_scaling

Hi @RalphT The custom plots are limited to 2. These perform the same measurement on each channel so deviation calculation is not possible here but you could use the Script tool for such.

Hi @mnorth The AnalogIn could be triggered on the DigitalOut start or each period/restart if you are using finite run: dwf.FDwfDigitalOutRunSet(hdwf, c_double(cSamples/hzRate)) dwf.FDwfAnalogInTriggerSourceSet(hdwf, trigsrcDigitalOut) Trigger on DIO1 could be done using the DigitalIn trigger detector but it is easier to hook the DIO1 to T1 and trigger AnalogIn on this. dwf.FDwfAnalogInTriggerSourceSet(hdwf, trigsrcExternal1) dwf.FDwfAnalogInTriggerConditionSet(hdwf, DwfTriggerSlopeFall)

Hi @LeRenne I don't see any specification but the DIN inputs look like this:

Hi @cagri See the application Help. 200mV/div = 2Vpk2pk

Hi @Buzz Could you attach a photo with you setup? Are you using single ended or differential input?

Hi @Oleg Udalov 1. The LD1/2 are for USB hub and LED9 the FPGA DONE signal. It looks like for you the USB hub is working and the Zynq boots and the FPGA gets programmed. See the WF app Help Troubleshooting section. Do you see "USB connect" printed ? 2. Scope inputs up to 50V 3. Unfortunately we do not provide repair service.

Hi @Kabron For more precise measurement with newer software version you can use the FFT view, Spectrum or Network Analyzer. See the default 'global' example. I don't recall the name of this measurement but I will let you know tomorrow....

Hi @klaff For Record more adjust the trigger position and others under the first Config button.

Hi @omegacore See the built-in Examples and Help tab.

Hi @Jim_G I'm glad to hear it is working again and thank you for the information.

Hi @Dante In Scope select trigger Source: Wavegen C# Since WF v3.18.29 it will trigger even when Wavegen is in "No sync..." mode or Run is continuous.

Szia @Andras Wow, this is an interesting solution :) Thank you for sharing it.
