[confused on python interface]

Hi @erikderuijter

I'm not familiar with this unmaintained 'WF_SDK' wrapper.
See the WaveForms SDK manual and examples.
The indexing in code is base 0, 4th is 3

[waveforms rpm package can not find installed qt5-qtbase package]

Hi @aminoh

It looks likes the following dependencies need to be installed manually:
sudo zypper install libQt5Multimedia5 libQt5Script5 libQt5SerialPort5

[Anyone used ADPro 5250 with current probe]

Hi @Kenji_T

The Probe option in the application is a software feature, it cannot have specifications.
This scales the oscilloscope input, voltage reading in the specified way and displays the units you want, similar to a math channel.
The used hardware probe should match the oscilloscope specifications.

Hi @Ostin Flores

For averaging calculate the average of multiple frequency domain results.
For triggered repetitive patterns/signals time domain averaging may provide better result.

[Frequency-dependent sweep levels for network analyzer]

Hi @mrb-bt

Amplitude setting and Channel# reading unit is V,  peak to peak voltage / 2

if(Channel2 == 0) return Target; // return initial amplitude
This is the amplitude very first amplitude setting for initial value. The readings are never going to be 0.0000000, always above 0. You can also use if(Frequency==0)...

Repeat = abs(Channel2 - Target) > 0.1; // repeat step if needed
Yes. The earlier will force the step to be repeated if the difference between the target and channel reading is above 100mV.
For dB use 20*log10(Channel#/Amplitude)

Hi @Shalin

I spent a few days with this and then realized the approach I had chosen would not work.
Please don't wait for this, I don't know when I will have time to try to make it happen again.

Hi @sintech

1. The next version will remember the last dialog positions.
2. I'll try to implement such option later.

[digilent adept runtime package header is not signed]

Hi @aminoh

The waveforms rpm is signed in the latest version:

The adept runtime release should be updated soon.
In the future the Linux packages will be signed automatically by the build script.
Thank you for the observation.

Hi @PhilipJ

Isn't the Events view helpful ?

 

The 'blue arrows' on signal row moves to the next/previous edge and on the protocol row to the protocol specific event/value.

Hi @fractalbrain

I'm glad it works. Thank you for the advice.

Hi @clb

The latest version adds auto leveling possibility for Network Analyzer.

Hi @liu

[Analog Discovery 3 - Issues Reading data from Digital Input C#]

Hi @HasNoCreek

See the examples and manual:

FDwfDigitalInTriggerSet(hdwf, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF) is not a valid trigger, DIN15:0 to be high and low at the same time and also to be either edge, rising or falling.

FDwfDigitalInStatus with false (0) instructs to not fetch capture data from the device.

Hi @liu

After I2C transfer configure the digital-out as you need.

[digilent adept runtime package header is not signed]

Hi @aminoh

The digilent rpm packages are not signed, select ignore.

[issue running I2C & digital IO output on Discovery 3]

Hi @liu

The protocols take control over digital-out and in device resource.
You can use the digital-io functions to control the DIOs.
You can use the trigger IOs to output a reference clock between 10-50MHz
You can also use the analog-out to generate digital clock with pulse signal 3.3V amplitude.

Hi @liu

See the following:

[AD3 4-Terminal Impedance Measurement: Current Injection & Voltage Sensing]

Hi @Pedro_Sousa

Yes, break.

Reference resistor is needed since the DUT is measured relative to this, and also for current limitation at lower impedance since the AWG output is voltage controlled.

[Transistor tester & emitter voltage]

Hi @Daniel M

It is not isolated.
The base and collector is controlled by W1 and W2 which generate signals relative to the emitter (virtual ground). If this is set to -5V by the V- power supply, the W1 and W2 for 0V output -5V. The transistor will receive signals from 0V to +10V relative to its emitter. Similarly, the emitter can be set to +5 by the V+ power supply, to have 0V to -10V

Hi @clb

Currently the Impedance Analyzer has such auto-level, CV/CC option. I'll try to add such options to the NA.

Hi @FrankL

You can add Zoom view and export this source, or write custom script for export with file write.
