Dear colleagues. I am preparing a software for noise measurement in Labview. I encounter this problem:
When I switch the instrument into FAST transfer mode for windows (the Instrument becomes a talker and host computer is a listerner), the instrument starts sending data over GPIB.
The short description of FAST mode is here SR830 FAST mode, and the data transfer is described in SR830 manual between pages 97-103.
However, at high data rates (>=128Hz) it hangs up even after few hundreds of samples taken, the number of samples vary.
I get the timeout error from VISA read. The VISA read function is set to synchronous reading. Without this setting, I cannot achieve higher data rate than 128Hz.
The cable between PC and Instrument is roughly 2 meters long, so I think this does not cause problem.
