UTG1000A Series 39
Phase deviation indicates the change between the phase of PM modulated waveform and the phase of carrier wave
phase. Settable range of PM phase deviation is from 0º to 360º, and the default value is 50º. If need to change,
press Parameter→Phase Deviation in turn.
Comprehensive Example
Firstly, make the instrument work in phase modulation (PM) mode, then set a sine wave with 200Hz from the
internal of the instrument as a modulation signal and a square with frequency of 900Hz and amplitude of 100mVpp
as a carrier wave signal. Finally, set the phase deviation to 200º. Specific steps are seen as following:
1) Enable Phase Modulation (PM) Function
Press Menu→Modulation→Type→Phase Modulation in turn to start the PM function.
2) Set Modulation Signal Parameter
Press Parametersoftkey and the interface will show as following:
Press corresponding softkey first, then enter required numerical value, and select the unit.
