Boonton 4540 Series RF Power Meter
Operation 4-25
4.5.14 Channel > Extensions Pg 1 > Corrections Menu (Pulse Mode)
The corrections menu contains items for adjusting correction factors for sensors. This menu consists of an offset adjustment,
frequency cal factor control, and a control for enabling or disabling temperature compensation for peak power sensors.
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Corrections > dB Offset
Description: Set a measurement offset in dB for the selected sensor.
This is used to compensate for external couplers,
attenuators or amplifiers in the RF signal path ahead of
the power sensor.
Menu Type: Numeric value.
Range: –300 to 300 dB
SCPI Command: SENSe[1|2]:CORRection:OFFSet
<numeric_value>
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Corrections > Freq CF
Description: Set the frequency calfactor currently in use on the
selected channel. Note setting a calfactor with this
command will override the ―automatic‖ frequency
calfactor that was calculated and applied when the
operating frequency was set, and setting the operating
frequency will override this calfactor setting.
Menu Type: Numeric value.
Range:
–3.00 to 3.00 dB
SCPI Command: SENSe[1|2]:CORRection:CALFactor
<numeric_value>
Main > Channel > Channel 1 | 2 > Extensions Pg 1 > Corrections > Temp Comp
Description: Set the state of the peak sensor temperature compensation system. This system
compensates for drift that might otherwise be caused by changes in the temperature of the
peak power sensors. When set to off, a warning will be displayed if the sensor
temperature drifts more than 4 degrees C from the autocal temperature. When ON, the
warning will not appear until temperature has drifted by 30C. This item does not apply to
CW Sensors, voltage probes, or peak power sensors without a temperature compensation
table.
Menu Type: Toggle.
Choices: On, Off
SCPI Command: SENSe[1|2]:CORRection:TEMPcomp <Boolean>
