Internal signal generator

[nl...@nlsa.com]

I need help interpreting Linrad’s display of its internal generator (F11).  My display looks nothing like the example on Leif’s website.

The signal does not appear to be swept in frequency and I don’t see the low-level signal at all.

My receiver is an IQ+ which has a zero-if bump in the center of its passband.  I think that the test signal is superimposed on this bump; perhaps this explains my weird S-graph display.

Any suggestions would be welcome.
