Marker Function
:CALCulate:MARKer[1]|2|3|4:X:STARt?
:CALCulate:MARKer[1]|2|3|4:X:STOP
:CALCulate:MARKer[1]|2|3|4:X:STOP?
These commands are now aliased as follows to preserve the old functionality as much as possible:
Old command Aliased to
:CALCulate:MARKer[1]|2|3|4:X:STARt :CALCulate:MARKer[1]|2|3|4:FUNCtion:BAND:LEFT
:CALCulate:MARKer[1]|2|3|4:X:STOP :CALCulate:MARKer[1]|2|3|4:FUNCtion:BAND:RIGHt
4. Arbitrary Marker Pair functionality
Another use case was to use the STARt and STOP commands to arbitrarily set the frequency
(time) of a delta marker and its reference marker without being in Band Power mode. This use
case is not supported with a backwards compatibility command, but since in the X-Series you
can arbitrarily set any marker’s value and any reference marker’s value, it is easy to fix this
problem in code; but the user will have to change their code.
Old command User must change to
:CALCulate:MARKer1:X:STARt :CALCulate:MARKer1:X
:CALCulate:MARKer1:X:STOP :CALCulate:MARKer2:X
(in the example marker 1 and marker 2 are used; in practice, use the reference marker number for
the STOP marker number, which is usually marker number+1)
5. Band changes with analyzer settings
In the past, when a marker pair was used to set the width of the band for Band Power, the
markers held their screen positions when analyzer frequency settings such as Span changed.
The result of this was that as the Span changed, the frequency difference and hence the width
of the band changed as well. In the X-Series, as a result of the change from position markers to
value markers, the width of the band remains constant as frequency settings of the analyzer
change.
6. Offscreen Markers
As a result of the change from position markers to value markers, markers can be at a frequency
which is offscreen, whereas in the past, they were clipped to the screen edges and hence were
