Marker Noise On/Off: Turns the markers into noise markers with units
of dBm/Hz. When this option is selected, the detection method is
automatically changed to RMS and the displayed value is compensated for
the noise bandwidth of resolution bandwidth filter.
Marker Table On/Large/Off: Causes a table to be displayed below the
sweep window. The table is automatically sized to display all markers that are
turned on. In addition to the marker frequency and amplitude, the table also
shows delta frequencies and amplitude deltas for all markers that have deltas
entered for them. If Large is selected, a large screen display opens
underneath the graph that displays both frequency and amplitude for the
active marker in large type.
All Markers Off: Turns off all markers.
Counter Marker On/Off: Sets the frequency counter mode for the active
marker. Marker frequency values are normally limited in resolution to
individual display pixels. Each pixel may represent multiple frequencies.
Using Counter Marker in association with Marker to Peak will result in the
exact frequency of the peak to a resolution of 0.001 Hz.
Set Marker To Channel: If a signal standard has been selected, pressing
this key brings up a dialog box to select a channel. Select a channel number
for the current signal standard, and the active marker will be set to the center
frequency of the channel.
If no signal standard has been selected, a message “No standard selected.
Press Enter or Escape to Continue.” is displayed. Press either button to leave
the settings as they were before the key was pressed.
Marker Style: This key changes the behavior of the reference markers.
If Fixed is selected, reference markers stay at the amplitude they were at
when the associated delta marker was turned on. If Tracking is selected, the
amplitude of the reference marker changes as the signal amplitude is
changed. Note that the reference marker tracks the amplitude, not the
frequency of a signal.
Marker 1 Reference: Selects whether Marker 1 is the reference for all six
delta markers, or whether each of the six reference markers has an
associated delta marker.
