SYST:PREF:ITEM:EDEV:DPOL - Determines whether External Devices remain activated or are de-activated when the VNA is Preset or when a Instrument State is recalled.
Applicable Models: All (Write-only) Performs a calibration of the power sensor. Calibration usually involves connecting the power sensor to the meter's 1 mW reference.

Applicable Models: All (Write-only) Performs a zeroing of the PMAR device. This command is always synchronous, so *OPC? is the only way to determine that the operation is complete. Set an I/O timeout of at least 20 seconds. Keysight P-Series sensors do ONLY Internal zeroing. These, and Keysight USB power sensors when Internal is selected, do NOT require disconnecting from the measurement path before zeroing. All other Keysight sensors do ONLY External zeroing. |
|
Parameters |
|
<name> |
String - Name of the power meter. |
[,SYNC,<value>] |
Optional argument for use with power sensors that support both internal and external types of zeroing such as Keysight USB power sensors. Choose from: SYNC,INTernal - Internal zeroing. Power is automatically removed from the sensor input before zeroing occurs (Default setting). SYNC,EXTernal - External zeroing. First remove the sensor input, then send this command. External zeroing is recommended for powers below -30 dBm with the U2000-Series sensors (-20 dBm for the H models). |
