Marker Function
In the table below, sweep_width = max(1,sweep_points–1) and sweep_points is the number of sweep points, set in the Sweep menu.It is legal to change the width of the band even if there is no marker function on. Generally this can only happen by sending the SCPI command since access to the menu is restricted if no marker function is on.Key Path Marker Function, Band Adjust
Remote Command :CALCulate:MARKer[1]|2|3|4|5|6|7|8|9|10|11|12:FUNCtion:
BAND:RIGHt <freq>
:CALCulate:MARKer[1]|2|3|4|5|6|7|8|9|10|11|12:FUNCtion:
BAND:RIGHt?
Example :CALC:MARK12:FUNC:BAND:RIGHt 20 GHz sets the right edge of the
band span of marker 12 to 20 GHz
:CALC:MARK:FUNC:BAND:RIGHt? queries the band span of Marker 1
Notes Units are those of the trace’s domain, Hz for frequency domain, s for time
domain. When the right edge is moved, the left edge stays anchored; thus, the
marker’s frequency will change.
Notes Sending this command selects the subopcoded marker
The unit of the parameter must match the current domain of the trace the
selected marker is on, or an invalid suffix error will be generated. If no unit is
sent the fundamental unit for the trace domain will be used (Hz for freq
domain traces, s for time domain traces).
Note that all the values provided in this table are only valid for frequency
domain traces. If the current domain of the trace is time domain, values and
unit will be different. In frequency domain, the Preset value is dependant on
the frequency range of the instrument. The default value 1.3245 GHz is
appropriate only if the instrument is a 26.5 GHz instrument (Option 526). In a
26.5 GHz Instrument, the default span is 26.49 GHz, so 5% of the span
corresponds to 1.3245 GHz.
Couplings Changing the Band/Interval Right necessarily changes the Band/Interval Span
and Band/Interval Center values
Band/Interval Span is set to 5% of span when any marker function is turned on
if and only if it is zero at that time
Preset If 0, Band/Interval Span is set to 5% of span, when a marker function is turned
on, which affects Band/Interval Right

screen, X-Series marker values are not limited and do not clip
