U2002A: SCPI sequence for measurements of low RF power

I am using SCPI to measure an (unknown) RF power level with a U2002A sensor. I cannot figure out how to make measurements below -32 dBm.

I use tho following power sensor initialization:


And then i query the power with the MEAS? command.

Below -32 dBm, the measurement fails due to a time-out.

Using the Power Panel, the sensor reports RF power even without a source connected, down to the noise floor.

How should I initialize and query the power sensor to avoid measurement time-out when measuring an unknown RF power level?
