• Press F1-F2: Provides a frequency sweep between the start frequency, F1, and the stop frequency, F2.
• Press F3-F4: Provides a frequency sweep between the start frequency, F3, and the stop frequency, F4.
• Press F5-DF:Provides a symmetrical frequency sweep about the center frequency, F5. The sweep width is determined by the dF frequency parameter.
• Press F6-DF: Provides a symmetrical frequency sweep about the center frequency, F6. The sweep width is determined by the dF frequency parameter. The Delta Frequency can be applied to any F0-F9 frequency.
Selecting one of the preset sweep range parameters F1-F2, F3-F4, F5-F6 and DF (Delta Frequency).
Setting Sweep Time
To set the analog sweep time, press SWEEP TIME.
Edit the current sweep time using the cursor control keys, the rotary data knob, or enter a new sweep time using the key pad and appropriate termination key. To close the open sweep time parameter once you have set the desired sweep time, press SWEEP TIME or make another menu selection.
To access the Analog Sweep Trigger menu from this menu, press TRIGGER. Set one of three trigger modes:
The sweep trigger is selectable from the trigger menu. There are three modes of sweep triggering for analog and step frequency sweep—automatic, external, and single. Press the TRIGGER button to display the trigger types:
• Auto (Automatic): The sweep continually sweeps from its start frequency to its stop frequency with optimal retrace time.
• External: The sweep recurs when triggered by an external TTL-compatible clock pulse to the rear panel AUX I/O connector.
• Single: A single sweep starts when the trigger key is pressed. If a sweep is in progress when the key is pressed, it aborts and resets.
To access the Sweep Trigger menu (Figure: TRIGGER Menu) from either the Analog Sweep or Step Sweep menus, press: SWEP | TRIGGER
TRIGGER Menu
A message showing the sweep trigger mode selected appears on the right side of frequency title bar.
If you select the single sweep trigger mode, the menu display adds the menu soft key TRIGGER. Pressing TRIGGER starts a single sweep. If a single sweep is in progress, pressing TRIGGER causes the sweep to abort and reset.
