Marker Function
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.
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.
Key Path Marker Function, Band Adjust
Remote Command :CALCulate:MARKer[1]|2|...12:FUNCtion:BAND:SPAN <freq>
:CALCulate:MARKer[1]|2|...12:FUNCtion:BAND:SPAN?
Example :CALC:MARK12:FUNC:BAND:SPAN 20 MHz sets the band span of marker 12 to 20 MHz
:CALC:MARK:FUNC:BAND:SPAN? queries the band span of Marker 1
Notes Units are those of the trace’s domain, Hz for frequency domain, s for time domain.
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 dependent 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 Span necessarily changes the Band/Interval Left and Band/Interval
Right values
Band/Interval Span is set to 0 when the marker is turned off
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, set to 5% of span, when a marker function is turned on
State Saved Saved in instrument state
Min 0 Hz
Max Infinity. Unlike legacy analyzers, where the markers were forced to be on screen, X-Series
marker values are not limited and do not clip
