rssd's Issues

R&S ZNA67 support?

Hi, I am trying to interface with the R&S ZNA67. Will this script work? My goal is to simply fetch sNp data. Can I simply connect my VNA to my machine over LAN and run the script, or do I have to set something up in advance first?

jaVISA

Current implementation uses pyVISA only. Would be nice to start w/ socket and fall-back to pyVISA

Wrong index?

should it not be from 4:4+numBytes? Because the format is

Reliability,#LN

We read L from [3], now we want to have [4:4+L]

I can't get measurement from NRP2 (Power Meter)

Describe the bug
I can't get measurement from NRP2 (Power Meter)

To Reproduce
Steps to reproduce the behavior:

running example NRP_AvgPwr.py

Console output

1
jav_RdErr : NRP2-->FETCH?

Done
<notRead>
jav_ClrErr: NRP2-->28,"Sensor not Idle"
jav_ClrErr: NRP2-->-410,"Query INTERRUPTED"

Process finished with exit code 0
