I keep getting the same error no matter what example program I run with the E4445A PSA. (Attached is a screen shot of the error window.) When I run the measurements manually everything functions as expected, however when I automate it with labview I get the following errors: Possible reason(s):
Instrument reports: +622,"External reference missing or out of range" +101,"Frequency Reference Unlock" +0,"No error"
Any help would be greatly appreciated, thanks.
