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.)
