Apply an Offset to a Phase-Modulated Output Signal
Using the PM Modulation screen the user can introduce an offset value for all
four parameters of the signal: Frequency, Level, Mod Rate, and Deviation. Once
the offsets are in place, they remain active until they are changed or until the
Instrument is powered on again.
To set an offset for one or more of the four signal parameters:
1. Create a phase-modulated output signal as described in the previous
2. Select the desired field: Frequency, Level, Mod Rate, or Deviation (parameter
3. Select the Offset for the parameter (bottom of the screen). An Offset label
4. Push the Offset softkey to select the offset field.
5. Push the Offset softkey, and enter the desired offset value. Notice that the
6. To toggle the offset value off and on, use the Toggle Offset softkey at the
7. To disable the offset, use the Offset Disable softkey at the bottom of the
8. Repeat this procedure, as needed, for each signal parameter.
Sweep Output Signal
The following procedures provide instructions for creating swept-frequency
output signals.
For the 96270A, sweep signals are available from the Leveling Head or
Microwave outputs. Push
Leveling is not available in the Sweep function.
The source is a digital synthesizer of frequency and level. All sweeps
are a sequence of finite steps between discrete frequencies as
determined by the user settings.
