High Accuracy Power Meter Measurement Guide (HIPM) (Option19) : HIPM Measurements : ZERO/CAL Menu
 
ZERO/CAL Menu
Access ZERO/CAL menu from the main menu. Zeroing the sensor is required in order to make low-level measurements. Before zeroing the sensor, connect it to the DUT (device under test) test port and remove RF power from the connection to a level 20 dB below the noise floor of the power sensor. The Zero/Cal menu also includes signal standards sub-menu that enables choosing a desired band from the predefined list. This menu holds good for both traditional and inline power sensors.

ZERO
With no power applied to the sensor and pressed On, the sensor is set to zero. This is recommended when making power measurements below – 20 dBm.
CAL FREQUENCY
Sets the measurement frequency. The frequency value is sent to the power sensor to apply the appropriate calibration factor.
