Remote command:
OUTPut<Ch>[:STATe]
Receiver Step Att.
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 4.7.31,
"Receiver step attenuators", on page 309.
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 35 dB in
steps of 5 dB. The analyzer rounds any entered value below the maximum attenuation
to the closest step.
Note: Receiver step attenuators are optional hardware (see Chapter 4.7.31, "Receiver
step attenuators", on page 309).
If an external switch matrix is used, this functionality can be configured in the Receiver
Level tab of the Chapter 5.12.2.2, "Port Settings dialog", on page 668.
Remote command:
[SENSe<Ch>:]POWer:ATTenuation
Preamp. Gain
Sets the gain of the Internal low power spur reduction amplifier (b1) and the Internal
low noise preamplifier (b2)
If an external switch matrix is used, "Preamp. Gain" is not available.
Remote command:
[SENSe<Ch>:]PAMPlifier2[:STATe]
[SENSe<Ch>:]PAMPlifier2[:VALue
5.8.2.2 Power Config dialog
Except for the ALC settings, which are covered in the ALC Config dialog, the "Power
Config" dialog offers the same settings as the Arbitrary Power tab of the Chap-
ter 5.12.2.2, "Port Settings dialog", on page 668.
5.8.2.3 ALC Config dialog
Enables and configures automatic level control (ALC) for the current channel.
Access:
●
Channel – [Pwr Bw Avg] > "Power" > "ALC Config..."
●
Port Settings dialog > "Arbitrary Power" tab > "ALC Params" column
