Power
Determines the output power at the test ports for the sweep types "Lin Freq", "Log
Freq", "CW Mode", and "Time". Also determines the default output power for "Segmen-
ted" sweeps, where the output power can be set per segment.
The setting has no effect for Power sweeps (R&S ZNL only), where the source power
is varied over a continuous range.
Remote command:
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
Start Power / Stop Power
Defines the sweep range for Power sweeps (R&S ZNL only).
Remote command:
SOURce<Ch>:POWer<PhyPt>:STARt
SOURce<Ch>:POWer<PhyPt>:STOP
Step Attenuators
Defines an attenuation factor for the received waves at each analyzer port. At least one
receiver step attenuator must be installed to use this feature; see Chapter 9.7.6,
"Receiver step attenuators", on page 303.
Receiver step attenuators are used to adapt the received signal level to the input level
range of the analyzer. They protect the instrument from being overloaded or damaged,
e.g. if the DUT is a power amplifier.
Attenuation factors are port- and channel-specific. Possible values are 0 dB to 30 dB in
steps of 10 dB. The analyzer rounds any entered value below the maximum attenua-
tion to the closest step.
Note: Receiver step attenuators are optional hardware (see Chapter 9.7.6, "Receiver
step attenuators", on page 303).
