Figure 2-23 PM Waveform Parameter Setup Interface
Table 2-14 PM Parameter Setup Menu Description
Phase offset note:
Phase offset can vary from 0° to 360°.
For the external source, offset is controlled by the
±
5V level on the [Modulation In]
connector. +5 V plus the selected offset, lower external signal levels generate less offset .

Frequency
Set modulation wave frequency (2mHz~20kHz)
Phase offset
Set the offset between the phase of modulation and
the carrier.

Phase offset
When external modulation is selected, the
modulation signal is input by the [Modulation
In] on the rear panel. And only the parameters
of Offset is needed setting here.
