Power
Determines the output power at the test ports. Also determines the default output
power for "Segmented" sweeps, where the output power can be set per segment.
Remote command:
SOURce<Ch>:POWer<PhyPt>[:LEVel][:IMMediate][:AMPLitude]
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
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 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
For the R&S
ZNLE Receiver Step Attenuators are not available and hence the "Step
Attenuators" section is always hidden.
Remote command:
RF Off All Channels
"RF Off All Channels" switches the internal power source for all channels off (if
checked) or on. Switching off the RF power helps to prevent overheating of a connec-
ted DUT while no measurement results are taken.
