External Frequency (V/GHZ) and Output Frequency to Controller Command
FPVOvv.vv,ss.ss,mm.mm
(Where v, s, and m are the arguments required to scale the voltage input at the PPM’s rear panel
FREQUENCY INPUT connection.) These are the same as described previously for FPRV.
This command causes the same action as the FPRV command but in addition, asks the PPM to output to
the controller the converted frequency information from the PPM’s rear panel external frequency input.
☛ NOTE:
When using FPVO and operating in the UPDC mode, there will be a stack build
up. Old frequency and power data will be output in applications such as swept power
measurements.
Sample Program:
10 ! PPM EXTERNAL FREQUENCY PLUS
20 ! FREQUENCY OUTPUT MODE
30 OUTPUT 704;UPDT ! SELECT OUTPUT
40 ! MODE. SELECT EXTERNAL FREQ
50 ! MODE AND COLLECT A DATA
60 ! POINT AND ITS FREQUENCY
70 G=5 ! VOLTS/GHZ
80 V=1 ! V/GHZ START FREQUENCY
90 F=2 ! SWEEPER START FREQUENCY
100 IMAGE 4A,3(DD.DD)
110 OUTPUT 704 USING 100;FPVO,G,V,F
120 TRIGGER 704
130 ENTER 704 USING 4A,7D,X,4A,6D;A$,B,C$,D
140 PRINT USING K,;POWER ,A$, IS ,B
150 PRINT USING K,;FREQ ,C$, IS ,D, GHZ
