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 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: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
See "Band Function Backwards Compatibility" on page 346 for more information
Band Left
Sets the left edge frequency or time for the band of the selected marker. The right
edge is unaffected.
Remote
Command
:CALCulate:MARKer[1]|2|…|24:FUNCtion:BAND:LEFT <freq>
:CALCulate:MARKer[1]|2|…|24:FUNCtion:BAND:LEFT?
Example Set the left edge of the band span of marker 12 to 20 GHz:
:CALC:MARK12:FUNC:BAND:LEFT 20 GHz
Query the band span of Marker 1:
:CALC:MARK:FUNC:BAND:LEFT?
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
Excess Active Function resolution may require up to 15 digits to allow sub-bucket resolution in narrow
spans with many points. Our calculations indicate 15 digits plus decimal point may be required. This will
not fit on the control; so the control value can only display to 12 digits, but the value in the active
function area should display to the full sub-bucket resolution
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 is generated.If no unit is sent, the fundamental unit for the trace domain is 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 are different. In frequency domain, the Preset value
is dependent on the frequency range of the instrument. The default value 1.3245 GHz is appropriate
