cmw_set_external_attenuation
Set external path loss between CMW and device under test so all power readings reference the DUT. Specify each application (GPRF, WLAN, Bluetooth, LTE); also tightens safety clamps.
Instructions
Declare the cable and fixture loss between the CMW connector and the DUT, so levels and measured powers refer to the DUT rather than the instrument. Without this every absolute power reading is wrong by the path loss. Attenuation is PER-APPLICATION -- pass the applications you are measuring with, because declaring it for GPRF does nothing for a WLAN or Bluetooth measurement. Setting it also tightens the safety clamps, which check both the DUT plane and the instrument connector.
