60 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
Basic Operation Preliminary
Modulating the Carrier Signal Preliminary
Example: Manual Control of Sweep
1. Set up either a step sweep (page 51) or a list sweep (page 57).
2. In the Sweep/List menu, select a parameter to sweep: Press Sweep > parameter > Return.
3. Select manual mode: Press More > Manual Mode Off On.
When you select manual mode, the current sweep point becomes the selected manual point.
4. If it is not already on, turn the RF output on: Press RF On/Off.
5. Select the desired point to output: Press Manual Point > number > Enter.
The progress bar changes to indicate the selected point.
6. Use the knob or arrow keys to move from point to point. As you select each point, the RF output
changes to the settings in that selection.
Modulating the Carrier Signal
To modulate the carrier signal, you must have both
• an active modulation format
and
• modulation of the RF output enabled
Example
1. Preset the signal generator.
2. Turn on AM modulation: Press AM > AM Off On (requires Option UNT).
You can turn on the modulation format before or after setting signal parameters.
The modulation format generates, but does not yet modulate the carrier signal.
Once the signal generates, an annunciator showing the name of the format appears, indicating
that a modulation format is active.
The parameters of the selected sweep point (point 3
of 6 in this example) define the signal available at the
RF Output connector.
When you enter a manual point,
the progress bar moves to and
stops at the selected point.
The SWMAN annunciator
indicates that the sweep
is in manual mode.
When you turn manual mode on, the
current sweep point becomes the
manual point.
The currently sweeping
parameter stops and
displays the selected point.
