Marker Commands
X2Y2source
X2Y2source
Command :MARKer:X2Y2source {CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N>}
This command sets the source for the X2 and Y2 markers. <N> specifies channels, functions,
TDR responses and waveform memories: 1, 2, 3, or 4. The source you specify must be
enabled for markers to be displayed. If the channel, function, TDR response or waveform
memory that you specify is not on, an error message is issued and the query will return
NONE
.
Query :MARKer:X2Y2source?
The query returns the current source for markers X2 and Y2.
Returned Format [:MARKer:X2Y2source] {CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N>}<NL>
Examples
This example selects channel 1 as the source for markers X2 and Y2.
10 OUTPUT 707;":MARKER:X2Y2SOURCE CHANNEL1"
This example returns the current source selection for the X2 and Y2 markers.
20 OUTPUT 707;":MARKER:X2Y2SOURCE?"
XDELta?
Query :MARKer:XDELta?
This query returns the time difference in seconds between X1 and X2 time markers if they
are both on. If both markers are not on, 9.37 will be returned.
Xdelta = time at X2 – time at X1
Returned Format [:MARKer:XDELta] <time><NL>
Example 10 OUTPUT 707;":SYSTEM:HEADER OFF"
20 OUTPUT 707;":MARKER:XDELTA?"
XUNits
Command :MARKer:XUNits {SECond | METer}
This command sets the units for horizontal display in TDR and TDT applications. The units
may be in seconds or meters relative to the reference plane. The marker mode must be
TDRTDT to use this feature.
Query :MARKer:XUNits?
Returned Format [:MARKer:XUNits]{SECond | METer}<NL>
Examples 10 OUTPUT 707;":MARKER:XUNITS METER"
Y1Position
Command :MARKer:Y1Position <Y1_position>
This command sets the Y1 manual marker position and moves the Y1 manual marker to the
specified value on the specified source if the Y1 marker is in manual state. <Y1_position> is
the current measurement unit value at Y1.
Query :MARKer:Y1Position?
The query returns the current measurement unit level at the Y1 marker position.
