Control Fields for Analog Measurements

Lvl (marker)

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

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. (See “Setting A Measurement Reference” on page 67.)

Lvl (normal marker)

Marker frequency (Marker Lvl) displays the frequency at the marker’s present position on the spectrum analyzer when the Norm/Delta field on the Marker controls menu is set to Norm. See Figure 6-2 on page 198.

See “Using the Spectrum Analyzer’s Delta Markers” on page 113 for more information about using the spectrum analyzer’s markers.

Operating Considerations

When switching from delta mode to normal mode, the delta marker becomes the normal marker.
