The extensions menu provides access to more advanced channel options such as trace filtering and channel units.
Additionally access to menu page two is provided. This menu is for sensors in Modulated Mode.
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Units
Description: Set the channel units. For power sensors, voltage is
calculated with reference to the sensor input impedance.
Note that for ratiometric results, logarithmic units will
always return dBr (dB relative) while linear units return
percent.
Menu Type: Pop-up Selection.
Choices: dBm, Watts, Volts, dBV, dBmV, dBµV
SCPI Command: CALCulate[1|2]:UNIT <character data>
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Corrections
Description: Selects the channel corrections menu.
Menu Type: Menu Select.
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Filter State
Description: Set the current setting of the integration filter on the
selected channel. ―Off‖ provides no filtering, and can
be used at high signal levels when absolute minimum
settling time is required. ―On‖ allows a user-specified
integration time, from 2 milliseconds to 15 seconds.
―Auto‖ uses a variable amount of filtering, which is set automatically by the power meter
based on the current signal level to a value that gives a good compromise between
measurement noise and settling time at most levels.
Menu Type: Multiple Choice.
Choices: Off, On, Auto
SCPI Command: SENSe[1|2]:FILTer:STATe <character data>
