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 Band Left necessarily changes Band Span and Band Center
Band Span is set to 0 when the marker is turned off, which means Band Left is set to the center value at
this time
Band 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 Span is set to 5% of span, when a marker function is turned on, which affects Band Left

Notes
The legacy command,
:CALCulate:MARKer[n]:X:POSition:STARt <param>
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 instrument first converts the specified span in trace points to the current X Axis Scale
Units (for example, frequency or time) of the trace upon which the marker resides. Then, that value is
sent to the
:CALC:MARKer[n]:FUNCtion:BAND:LEFT <param>
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 (buckets) by
translating back based on the current X Axis Scale settings at the time the query is sent
See "Band Function Backwards Compatibility" on page 346 for more information
Band Right
Sets the right edge frequency or time for the band of the selected marker. The left
edge is unaffected

:CALCulate:MARKer[1]|2|…|24:FUNCtion:BAND:RIGHt <freq>
:CALCulate:MARKer[1]|2|…|24:FUNCtion:BAND:RIGHt?
Example Set the right edge of the band span of marker 12 to 20 GHz:
:CALC:MARK12:FUNC:BAND:RIGHt 20 GHz
Query the band span of Marker 1:
:CALC:MARK:FUNC:BAND:RIGHt?
