MS269x has lower noise than MS869x

One of features of MS269x series is low level of its noise floor. Actually MS2691A shows apparent peaks though MS8609A cannot show them.

I sampled traces below with the same transceiver, cables and external attenuator.

C450_430

MS8609A showed higher noise floor and it could not detect a proper peak frequency.

On the other hand MS2691A showed lower noise floor and we can see some apparent peak points.

MS269x series has lower noise than MS860x series, also MS268x series. MS860x series and MS268x series are the same generation products.

Additionally, sweep time of MS2691A is half as short as MS8609A nevertheless with the same sweep settings. Low noise and fast sweep. It is very good.

(Additional comment on April 3, 2017)
A sweep across two frequency band sectors may take longer time.
MS8609A may have a band switch frequency between 1 GHz and 3 GHz.
