Patterns and I2C Instrument not working together
attila replied to Rohan16's question in Test and Measurement
Hi @Rohan16 You can use StaticIO to drive the DIO 0/1. If not Z this has higher priority over the DIO than Patterns and Protocol.- 3 replies

amplifier source load impedance measurement
attila replied to bsaulquin's question in Test and Measurement
Hi @bsaulquin The Impedance Analyzer is not suitable for such measurement. This is intended for low power testing of component, passive filters... The amplifier needs high power reference load. https://sengpielaudio.com/calculator-InputOutputImpedance.htm Here I used an floating external supply and 6.2R power resistor, I had at hand, connected to the output. I measured an output impedance of 0.31 Ohms. Here R1 is without and C2 is with load. For me the THD and noise my be high due to the wiring or this is just a cheap amplifier. -

Hi @bsaulquin See the following: https://www.google.com/search?q=how+to+measure+amplifier+output+impedance+%3F For frequency response use the Network Analyzer and the spectrum options under Magnitude. -

waveforms rpm package can not find installed qt5-qtbase package
attila replied to aminoh's question in Test and Measurement
Hi @aminoh The package naming is different in various rpm repos, like libQt5Something5 or libqt5Something5 or qt5-something-5 This problem will be solved later since it requires updating the build machines. Until then, for some distributions, the packages need to be installed manually. -
waveforms rpm package can not find installed qt5-qtbase package
attila replied to aminoh's question in Test and Measurement
Hi @aminoh It should work. The device communication is done by adept.runtime package. I'll try to fix this Qt application dependency, but I'm having hard time using openSUSE with VBox. -

Hi @Rohan16 Yes, add manually, use workspace Use Ctrl+Space or check Edit/'Code completion' but too many suggestion can be disturbing in writing, see the Help tab

waveforms rpm package can not find installed qt5-qtbase package
attila replied to aminoh's question in Test and Measurement
Hi @aminoh If the libqt5 multimedia, script and serialport are installed the 'base' is already installed. (All these dependencies should be installed automatically when installing waveforms, but it looks like suse would need different requisite naming.) Try to install waveforms with force, option 2 -
Hi @bryan78 Which software version are you using ? Could you provide more detail about the issue ? It seems to me working correctly. I notices some delay with Protocol/UART/Spy at lower rates, which needs improvement in the 'firmware'.

Why is FDwfAnalogInStatus always used in loops?
attila replied to Marcus Watson's question in Test and Measurement
Hi @Marcus Watson If you are capturing up to device buffer size of samples you can use acqmodeSingle, see WF SDK/ samples/ py/ AnalogIn_Acquisition.py, AnalogIn_Trigger.py.... This does not need loop, but you should verify if the capture is done with FDwfAnalogInStatus before reading the data. The record mode is for capturing more samples at lower rate, using data streaming and this requires loop to transfer the chunks of data. -
Hi @Al B. The 4 USB host ports are only available with Linux boot mode.

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
