Marker: Lvl
This measurement field displays the signal level of the current marker 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. (See
"Setting A Measurement Reference" on page 70.)
Marker: Time
This measurement displays the time elapsed from the trigger point to the current
marker position.
The REF SET function can be used with this measurement to display time relative
to a specific position. (See
"Setting A Measurement Reference" on page 70.)
