Marker Operations

Marker operations transfer the active marker’s frequency into the sweep settings. This lets you quickly zoom in on a feature by using marker positions to define start, stop, center, or span values.

Set sweep start from a marker

1. Move the marker to the desired lower frequency boundary.
2. Tap MARKER → OPERATIONS → >START.
3. The sweep start frequency updates to match the marker position.

Set sweep stop from a marker

1. Move the marker to the desired upper frequency boundary.
2. Tap MARKER → OPERATIONS → >STOP.
3. The sweep stop frequency updates to match the marker position.

Set center frequency from a marker

1. Position the marker on the feature you want to center on (e.g., a resonance dip).
2. Tap MARKER → OPERATIONS → >CENTER.
3. The sweep center frequency shifts to the marker position, keeping the current span.

Set span from a marker

1. Position the marker at the frequency that defines half the desired span.
2. Tap MARKER → OPERATIONS → >SPAN.
3. The sweep span adjusts based on the marker position.

Set a marker to an exact frequency

1. Select the marker.
2. Tap MARKER → SET FREQ.
3. Enter the frequency using the on-screen keypad.
4. Tap Ok to confirm.

Tip

Quick access: Long-press the middle hardware button to open the frequency entry screen for the active marker without navigating through the menu.

Typical workflow: zoom in on a feature

A common use of marker operations is quickly zooming in on an area of interest:

1. Run a wide sweep to identify the feature.
2. Place Marker 1 at the left edge of the region you want to examine.
3. Tap MARKER → OPERATIONS → >START.
4. Place Marker 2 at the right edge.
5. Tap MARKER → OPERATIONS → >STOP.
6. The sweep now covers only the region between the two markers.

Note

After narrowing the sweep range, you may want to recalibrate for best accuracy across the new frequency span.
