On this website there is a free software package called FRA that you can download to run functional tests on your FRA. Click here to locate it. The functional test described below is for determining if the generator and voltage analyzers of your FRA are generating and measuring AC voltage correctly
Install and start FRA software-Click on System and select your FRA and GPIB address, click Save/Test FRA, then Exit back to the main screen
Click on Transfer function and select single channel. Click on channel and select channel 1. Connect the generator output to channel 1 Hi (Input Vi Hi) using one of the 1 meter BNC cables that came with your instrument.
Select Generator and set the AC amplitude to 1 and the frequency range from 100 kHz-1 Hz.
Click on exit and then click on Measure Sweep. The result you get for magnitude should be very close to 1 (+/-5%). Regardless of the result you get, you should then repeat the procedure for Channel 2 Hi (input V2 Hi). If both channels show the same good result then there is nothing wrong with your generator or voltage inputs. If either or both show a bad result your instrument may need service and you should contact Solartron Analytical technical support.
