2. Enter the PM modulation page directly through the shortcut menu.
3. Enter the MOD interface via the MOD button and switch to the PM modulation page.
2.4.3.1 PM State
Select MOD ->PM->PM State to turn PM on or off.
2.4.3.2 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.
2.4.3.3 PM Shape
Select MOD ->PM->PMShape. After setting the source to ―Int‖ or ―Int+Ext‖, you can select
PM waveform as ―Sine‖ or ―Square‖.
2.4.3.4 PM Rate
Select MOD ->PM->PMRate, then you can set the PMrate.
1. The sine wave modulation frequency range is 0.01Hz~100kHz
