CALCulate Subsystem Commands
CALCulate:MARKer[1|2|3|4]:TRACe TRA|TRB|TRC|TRD|TRE|TRF
CALCulate:MARKer[1|2|3|4]:TRACe?
Places the marker on a particular trace.
CALCulate:MARKer[1|2|3|4]:X?
Returns the X-axis value of the normal marker. When the delta function is
ON
,
the absolute X-axis value of the delta marker is returned. When the bandwidth
function is
ON
, the X-axis value of the center marker is returned.
The units of the value returned by the query is determined by the
CALCulate:MARKer:X:READout state. For READout of FREQuency, the units
returned are in Hertz. For READout of WAVelength, the units returned are
meters. For READout of TIME, the units are in seconds.
Sending the query when the specified marker is
OFF
will generate a Settings
conflict error.
CALCulate:MARKer[1|2|3|4]:X:FREQuency <numeric_value>
S
ets the X-axis value of the normal marker. When the delta function is
ON
, the
absolute X-axis value of the delta marker is controlled. When the bandwidth
function is
ON
, the X-axis value of the center marker is controlled.
Sending the command when the specified marker is
OFF
will turn the marker
ON
and place the marker at the desired position. Sending the command when
the instrument is in a zero span will generate a Settings conflict error.
CALCulate:MARKer:X:READout FREQuency|WAVelength|TIME
CALCulate:MARKer:X:READout?
Sets the X-axis readout for frequency or wavelength when the instrument is in
a non-zero span. This setting controls only the normal marker X-axis and the
delta reference readout. The bandwidth and delta offset markers have their
own settings. This setting controls all four normal markers.
Trying to set the READout to TIME when in a non-zero span generates a Set-
tings conflict error. Trying to set the READout to FREQuency or WAVelength
when in zero span also generate a "Settings conflict" error. When the instru-
ment is set to zero span, the readout will automatically change to TIME. This
command is primarily useful for non-zero spans.
