PM Source
Select MOD ->PM->PM Source to set “Int” or “Ext” or “Int + Ext”. The default is
“Int”.
1. Int
Use the internal LF generator as the modulation signal source for PM. The PM
Shape, PM deviation, and PM rate can be set.
2. Ext
Use an externally applied modulation signal. The external signal is input via the
EXT MOD INPUT connector with an impedance of 50 ohms
3. Int + Ext
Use both, the internal and externally applied modulation signal; this technique can
be used to perform two-tone PM.
PM Shape
Select MOD ->PM->PM Shape. After setting the source to “Int” or “Int+Ext”, you
can select PM waveform as “Sine” or “Square”.
