The Markers Menus

To set markers to measure bandwidth

1Press the front-panel Markers key.

2Select an active marker.

3Place the marker on the peak of the signal to be measured by pressing the PEAK SEARCH softkey.

4Press the Marker BW.... softkey.

5Select a pre-defined bandwidth or use the knob, step keys, or numeric entry pad to enter the active marker bandwidth amplitude for the active marker.

If a peak search is not performed, then pressing the Marker BW.... softkey finds the bandwidth around the currently active marker. If the bandwidth markers cannot be placed at the selected value, an error message, such as “BW not found” will be displayed.

To perform a peak search using a marker

1Press the front-panel Markers key.
