Fields

Marker: Lvl

This measurement field displays the signal level of the current marker position.

GPIB Example

“DISP CSP;MEAS:CSP:MARK:LEV?“

queries the amplitude at the marker’s present position.

Operating Considerations

The unit-of-measure for this field is dependent on the source of the signal being measured. For instance; when measuring a signal from the AUDIO IN connector, the amplitude is measured in Volts. When looking at a signal from the FM demodulator, the amplitude is given in units of kHz.

When the Vert Offset field is 0.00, the displayed marker level is referenced to the center line generated by the vertical offset feature, not the center line of the screen.

The REF SET function can be used with this measurement to display levels relative to a specific value.

The marker position can be adjusted using the Marker Pos field.
