Subject: [HP-Agilent-Keysight-equipment] E4407B strange peak shapes at low RBW

Hello Everyone,

I am working on my E4407B and found that it has funny peak shape when I use low Resolution Bandwidths.
The shape is not collected into one peak, instead its smeared as in the pictures.
The bad shapes occur at RBW 300kHz, 100kHz. I don't think its there at 30kHz, but I could be wrong..
Anybody have any clue?



Best regards
