Hello,
I have a LCR-meter 4284A that I use to measure the impedance of a device.
The impedance of the device changes with the position of a target, with temperature and with the frequency of the applied signal.
The device is put in a stove and mounted on a bracket which allows to move a target from outside the stove and measure its position.
A PC can communicate with the RLC-meter through a GPIB bus.
The operating mode I would like to follow is :
1) configure the RLC-meter, in particular define a list of frequencies for the test signal, through an application running on the PC,
2) put the application in a wait state,
3) set manually a temperature, set manually a position of the target and launch the sequence of measurement when I push the trigger button of the RLC-meter front panel,
4) when all the measurements are finished, the RLC-meter should send a trigger to the PC the launches the transmission of the measurements from the RLC-meter to the PC,
5) when all the data has been collected and stored in a file, repeat the operation from step 3 -on until all predefined temperatures and target positions have been tested.
Does someone know the set of SCPI instructions that would allow data to be transmitted from the RLC-meter to the PC, even if the PC was the controller at the begining of operation. I have not found any example in the operation manual of the RLC-meter.
Thank you for your support.
Thomas.
Hi Thomas,
You can read the measurement results from your PC using "fetch?" command after the list sweep measurement is completed.
For more information, please refer to "Remote Control" section of 4284A operation manual.
