Main > Channel > Channel 1 | 2 > Extensions Pg 2 > Frequency
Description: Set the RF frequency for the current measurement. The appropriate frequency calfactor
from the sensor’s EEPROM table will be interpolated and applied automatically.
Application of this calfactor cancels out the effect of variations in the flatness of the
sensor’s frequency response. If an explicit calfactor has been set, either manually or via
the SENSe:CORRection:CALFactor command, entering a new frequency will override
this calfactor and use only the ―automatic‖ frequency calfactor.
Menu Type: Numeric value.
Range: 0.001 GHz to 110.00 GHz (sensor and video bandwidth dependant)
SCPI Command: SENSe[1|2]:AVERage <numeric_value>
