Step Attenuators
Defines an attenuation factor for the received waves at each analyzer port.
Attenuation factors are port- and channel-specific. They are used to adjust the received
signal level at the receive port(s) 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. At least one
receiver step attenuator must be installed to use this feature; see
Chapter 4.7.15,
"Receiver Step Attenuators" , on page 217.
Possible values are 0 dB, 10 dB, 20 dB, and 30 dB. The analyzer rounds any entered
value below the maximum attenuation to the closest step. UP and DOWN increment/
decrement the attenuation in 10 dB steps.
Note: Receiver Step Attenuators are not available for R&S ZNB20, R&S ZNB40 and
R&S ZNBT20.
If the number of physical ports (on the VNA and connected switch matrices) is higher
than 4, the "Step Attenuators" input fields in the "Power" softtool are replaced by a
"Step Attenuators" button that opens the following dialog:

5.8.3 Time Domain X-Axis Tab
If the active trace is a time domain trace, these settings define its stimulus axis.
Time domain analysis requires option R&S ZNB-K2 / R&S ZNBT-K2. If this option is
not installed, the "Time Domain X-Axis" tab is hidden.
