Marker Fctn 12
Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 225
Marker Count
Turns the marker frequency counter on and off for any active marker. If no marker is active
before Marker Count is pressed, a marker is activated at the center of the display. An
asterisk (*) may appear in the upper-right area of the display along with the message Cntr 1
(the number in the message depends on the active marker). If the marker count function is
on and you change the active marker, the new active marker will use marker count. If the
frequency counter function is on with only one active marker and that marker is turned off,
then the frequency counter function is turned off. If the frequency counter function is on
with multiple markers turned on and only one is turned off, the frequency counter function
stays on. Marker Count frequency readings are not affected by the frequency offset
function.
In
Zero Span the counter continues to function, counting any signal near the center
frequency of the N8201A.
Setting Marker Fctn to Off does not turn Marker Count off.
Key Path: Marker Fctn, Marker Count
State Saved: If Marker Count is on, that setting is saved in the instrument state.
Factory Preset: Off
Remote Command:
:CALCulate:MARKer[1]|2|3|4:FCOunt[:STATe] OFF|ON|0|1
:CALCulate:MARKer[1]|2|3|4:FCOunt[:STATe]?
:CALCulate:MARKer[1]|2|3|4:FCOunt:X?
Remote Command Notes:
Using the CALC:MARK[1]|2|3|4:FCO command.
If the specified marker number in the command is not the active marker, it becomes
the active marker. If the marker number is not turned on, it is first turned on and then
it becomes the active marker. Once the marker count function is turned on, it will be
on for any active marker, not just the marker number specified when the command
was sent.
Using the CALC:MARK[1]|2|3|4:FCO:X? query.
The query returns a 1 only if the marker count function is on and the marker number
selected is the currently active marker. The query returns 9e15 if the marker count
function is off, or if the specified marker is not the active marker.
