Hi Bill,
Thank you for your detailed response.
First of all, I'm happy with the SMIQ and I included that only
to show that the spurs do not come out of the spectrum analyzer
(which is an FSU indeed).
Regarding the E4437B: You are right that the data sheet specs
allow this but I find it rather
Hi, Wolfgang. Both of your generators appear to be well within their
datasheet specifications based on the spectrums you posted.
The datasheet for that ESG-DP (digital modulation with high spectral
purity) model is at:

The E4437B
Hi,
I just got a used/refurbished E4437B which I wanted to use as a
all-purpose RF generator primarily for 3-4 GHz.
Unfortunately, I'm seeing strange spurs for frequencies above 2.4 GHz,
see the green curve in the attached image.
The yellow curve is an SMIQ03 for comparison.
