Boonton 4500B RF Peak Power Analyzer
Remote Operation 5-44
5.5.8 MARKer Subsystem
The MARKer group of commands is used to configure and locate measurement markers (cursors) at specific points on the
processed measurement waveform. FETCH? or READ? queries may then be used to retrieve measurements at the two
markers and in the interval between them. Markers are used in Pulse mode to perform measurements at or between two time
offsets relative to the trigger, and in Statistical mode to measure the power at a particular statistical percent, or the percent at
a specified power level. In Pulse mode, the markers can only be placed on the visible portion of the trace (as defined by the
timebase and trigger delay settings), while Statistical mode markers may be placed at any power or percent value and will
still return readings.
MARKer: ASSIgn
Description: Set or return the channel to which the specified marker display window, MK1 or MK2 is
assigned. The marker math result window will show the result of the specified marker math
operation on the selected marker sources. Some combinations of markers sources and math
operations are disallowed. Set ACTIVE to automatically select the displayed channel.
Syntax: MARKer[1|2]:ASSIgn <asc>
Argument: <asc> = {ACTIVE, CH1, CH2, CHM, TRIG1, TRIG2, MEM1, MEM2}
Valid Modes: All
MARKer:GROUp
Description: Set or return the marker grouping rule. If BOTH is set, Marker 1 and Marker 2 will be forced to
the same channel assignment. If EACH, is set, Marker 1 and Marker 2 will have independent
channel assignments. If MARKer:GROUp BOTH & MARKer:ASSIgn ACTIVE are set, Marker 1
and Marker 2 will be assigned to the displayed channel.
Syntax: MARKer:GROUp <asc>
Argument: <asc> = {BOTH, EACH}
Valid Modes: All
