SSA2021X - 20 dB attenuator sufficient?
<< < (8/8)
tautech:
FWIW
In all SSA/SVA models, Attenuator settings in the Amplitude menu are best left set to Auto and any additional external attenuation compensated for in the Ref Offset settings so to negate any need for level maths in the head on the fly and to have Marker level measurements autocorrect for external attenuation values.

A couple of no signal screenshots showing these settings, one with external 10dB attenuator added and Ref Offset changed. Note the marker level remains similar only reading the noise in the no signal sweep.

As levels get closer to 0dB and above, these analyzers will auto-change internal attenuation to protect themselves.
Use a Manual attenuator setting at your own risk.
