Rohde & Schwarz SCPI Driver
Project description
Rohde&Schwarz Python SCPI Driver
Project goals:
-
Example python drivers
- FSW, Vector Spectrum Analyzer
- SMW, Vector Signal Generator
- VSE, Vector Signal Explorer
- OSP, Switch Driver
- NRQ, Frequency Selective Power Sensor
-
Example code
- Automated test example
- Instrument speed/repeatability evaluation
- Proof of concept/Demo code
-
RSSD is in development. Package APIs may change. We recommend users "freeze/save" package version prior to use.
Drivers:
- Driver Structure:
- pyvisa → yaVISA.py → <instr>_Common.py →
- <instr>_<OptionName>_Kxx.py
- <instr>_<OptionName>_Kxx.py
- <instr>_<OptionName>_Kxx.py
- pyvisa → yaVISA.py → <instr>_Common.py →
- yaVISA: pyvisa wrapper
- yaVISA.jav_Open(sFileName, sLogFile): Open VISA link
- yaVISA.write(sSCPI): Write SCPI command
- yaVISA.query(sSCPI): Query SCPI command
- yaVISA.jav_logscpi(): Turn on "SCPI to file"
- yaVISA.jav_OPC_Wait(sCmd): Wait for longer commands.
- Please see code for full list of commands.
- FSW: Vector Spectrum Analyzer
- Developed & Tested with FSW
- FSW & VSE share many commands.
- Possible compatibility: VSE; FPS; FSV;
- SMW: Vector Signal Generator
- Developed & Tested with SMW
- Possible compatibility: SGS; SGT; SMB; SMBV
- VSE: Vector Signal Explorer SW
- Developed & Tested with VSE
- Drivers represent VSE commands not in FSW code
- OFDMVSA K96 code resides here as well
- Possible compatibility: FSW
Getting Started
Installing
