Backwards Compatibility
Notes

The old command,

:CALCulate:MARKer[n]:X:POSition:SPAN <param>

was used to set the span between a delta marker and its reference marker in trace points
(buckets) in Span Pair mode. There is no new command for setting the span 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. Then, that value is sent to the

:CALC:MARKer[n]:FUNCtion:BAND:SPAN <param>

command to set the span of the marker’s Band Function.

The query form of the command will return the marker function span in trace points (buckets) by
translating back based on the X Axis Scale settings at the time the query is sent.

Initial S/W Revision

Prior to A.02.00

Band/Interval Left

Sets the left edge frequency or time for the band of the selected marker. The right edge is
unaffected.

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.

Remote Command

:CALCulate:MARKer[1]|2|...12:FUNCtion:BAND:LEFT <freq>

:CALCulate:MARKer[1]|2|...12:FUNCtion:BAND:LEFT?

Example

:CALC:MARK12:FUNC:BAND:LEFT 20 GHz sets the left edge of the band span of marker 12 to 20
GHz

:CALC:MARK:FUNC:BAND:LEFT? 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 left
edge is moved, the right edge stays anchored; thus, the marker’s frequency will change.

Notes

Sending this command selects the subopcoded marker
