Marker Function
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 Left necessarily changes the Band/Interval Span and Band/Interval
Center values.
Band/Interval Span is set to 0 when the marker is turned off so that means Band/Interval Left is
set to the center value at this time.
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 Left.

Compatibility SCPI The legacy command,
:CALCulate:MARKer[n]:X:POSition:STARt
was used to control the Reference marker in trace points (buckets) in Band Pair/Delta Pair mode.
There is no new command for setting the start of a Band Function in trace points. So, when this
command is received, the analyzer first converts the specified span in trace points to the current
X Axis Scale Units (e.g., frequency or time) of the trace upon which the marker resides.
:CALC:MARKer[n]:FUNCtion:BAND:LEFT
command to set the start of the marker’s Band Function.
The query form of the command will return the marker function LEFT value in trace points
