PXIe-5663e spurious performance

PXIe-5663e spurious performance

‎05-18-2020 11:41 AM

I am driving a PXIe-5663e VSA using a PXIe-5673e VSG producing a -10 dBm CW tone at 2.265123 MHz.  The VSA full-span trace shows the incoming signal at -17.5 dBm (due to cable and filter losses) but also spurious signals at 1.9055 GHz @ -17.4 dBm, 855.205 MHz @ -44 dBm and  501 MHz @ -33 dBm.  Is this spurious performance typical for this instrument?
