Receiver Step Attenuators
Options R&S
ZNL3|6-B31 and R&S
ZNL3|6-B32
Receiver step attenuators are used to adjust the received signal levels to the input
level range of the analyzer to avoid damage to the instrument, e.g. if the DUT is a
power amplifier. The attenuation values can be set between 0 dB and 30 dB (in 10 dB
steps); see
on page 291. The following step attenuators are availa-
