Step Atten. b2
Opens the numeric entry bar to set the attenuation for the received wave b2. This function is available
only if a receiver step attenuator is installed at port 2.
The attenuation is used to adjust the received signal level at port 2 to the input level range of the
analyzer in order to avoid damage to the instrument, e.g. if the DUT is a power amplifier . The range of
values depends on the analyzer model.
Using a single step attenuation b2 corresponds to a standard test setup with 0 dB generator attenuation
and attenuation of the (amplified) wave received at test port 2. The attenuation factors for all received
and generated waves can be set via Step Attenuators.

Meas. Bandwidth
Sets the measurement bandwidth of the IF filter. Step Atten. b2 opens a submenu (and displays a range
of softkeys) to directly select bandwidths between 10 Hz and 1 MHz:
