Analog Measurements - Screens and Control Fields

Lvl (marker)

This measurement field displays the signal level of the signal at the

current marker position on the spectrum analyzer. (See Figure 5-1 on

page 133.)

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 45.)
