Cal Factor Examples
Entering a frequency causes the power meter to use frequency calibration factors which are stored in the
power sensor’s internal EEPROM. Generally, frequency calibration factors are stored in one gigahertz
steps.
Two methods are available for frequency entry. Use SENSe:CORRection:FREQuency to enter a specific
carrier frequency, or use SENSe:CORRection:VPROpf to enable the meter’s voltage proportional to
frequency input BNC (See front panel of the meter).
A.7.1
Cal Factor Example 1
The following program automatically applies the correct cal factor for an 8.23 GHz measurement
frequency to the measured data value.
310
ASSIGN @Pwr_mtr to 70101
320
CLEAR @Pwr_mtr
330
WAIT 1
350
OUTPUT @Pwr_mtr;CALC1:MODE NORMAL
! Can ONLY send Cal Factor Correction Commands in
! Normal Mode!!
360
!
370
OUTPUT @Pwr_mtr;SENS1:CORR:FREQ 8.23E9
! Applies Cal Factor for 8.23 GHz to measurement data.
380
!
400
OUTPUT @Pwr_mtr;MEAS1?
! Measures Power of 8.23 GHz signal.
410
ENTER @Pwr_mtr;Rdg

A.7.2
Cal Factor Example 2
The following program steps from 1.8 GHz to 2.2 GHz in 10 MHz intervals. The measurement at each
step is automatically corrected for cal factor.
340
ASSIGN @Pwr_mtr to 70101
350
CLEAR @Pwr_mtr
360
WAIT 1
370
REAL Rdg(41)

OUTPUT @Pwr_mtr;CALC1:MODE NORMAL
! Can ONLY send Cal Factor Correction Commands in
! Normal Mode!!
400

410
FOR I=1 TO 41
420
!
430
Freq=1.8E+9+(I-1)*1.E+7
440
OUTPUT @Pwr_mtr;SENS1:CORR:FREQ;Freq
! Applies Cal Factor to measurement data.
450
!
460
OUTPUT @Pwr_mtr;MEAS1?
470
ENTER @Pwr_mtr;Rdg(I)
480
OUTPUT @Pwr_mtr;SENS1:CORR:FREQ?
! Power meter outputs freq setting to confirm command
! reception.
490
ENTER @Pwr_mtr;Frq(I)
500
