e Set Frequency Deviation
The frequency deviation indicates the change between the phases of FM modulated waveform
and the phase of carrier wave phase. Settable range of PM frequency deviation is from DC to half
of current carrier wave bandwidth, and the default value is 1kHz. After enabling FM function, the
phase deviation can be modified by pressing |FregDev |.
® Frequency deviation S carrier wave frequency, if the value of frequency deviation is set higher
than carrier wave frequency, the device will automatically set the offset value to the maximum
allowable carrier wave frequency.
@ Frequency deviation + carrier wave frequency S the allowed maximum frequency of current
carrier wave. If the frequency deviation value is set to an invalid value, the device will automatically
set the offset value to the maximum allowable carrier wave frequency.
© Comprehensive Example
First run the instrument in frequency modulation (FM) mode, set an internal square wave of 2kHz
as the modulation signal and a sine wave with frequency of 10kHz and amplitude of 100mVpp as
the carrier signal. Finally set phase deviation to be 5kHz. The specific steps are as follows:
1) Enable Frequency Modulation (FM) Function
Press |Mode | >| FM |to enable FM function.
1,000,000,00 kHz
2) Set Modulation Signal Parameter and Waveform
After step 1), press | ModWavel nd (Square |to select square wave as modulation waveform.
Press |[MadFreq), enter 2 by numeric keypad, and select parameter unit kHz).
