Mod/PM Operation menu selections and parameters include PM Freq,
Phase Dev, Type, Shape, and Source as follows:
PM Freq - This parameter sets the frequency at which the output
amplitude shifts between the carrier amplitude and 0. The internal
source frequency range is 2 MHz to 50 kHz.
Phase Dev - This parameter sets the maximum phase deviation.
Values range from 0° to 360°.
Type - Phase Modulation.
Shape - Choose the waveform shape type (used as a carrier
waveform) for modulation. Sine, Square, Triangle, UpRamp,
DnRamp, Noise, or Arb waveforms may be modulated, while
Pulse, and DC cannot.
Source - Select Internal or External. If External is selected, use the
Trig/Gate/Fsk/Burst connector on the Back Panel (on page 14).
Generating Sweep Waveforms
Specific waveform types may be swept (as carrier waveforms) using the
WaveStation. Sine, Square, Ramp, or Arb waveforms may be swept,
while Pulse, Noise, and DC cannot. Frequency sweep mode uses the
WaveStation to sweep from the start frequency to the stop frequency at
a specified sweep rate.
The first step in creating a sweep waveform is to press the Sweep button
on the Front Panel (on page 13).
PLEASE NOTE THE FOLLOWING:
When using WaveStation (or any signal generator) it's important
to understand the relationship between the Main Waveform Type
buttons, the Waveform Signal Conditioning function buttons, and
the Save/Recall, Utility, and Help function buttons. See Combined
Use of Waveform, Function, and Configuration Buttons (on page
23).
Default values for many controls can be set using certain options
available on the Utility menu. Learn more in Main Utility
Operations (on page 62).
