Note that the optimization can only be applied, if all channels in the current setup are
in single sweep mode (INITiate<Ch>:CONTinuous OFF, and if there is no ongoing
sweep sequence. Any change in the current setup or a wrong sweep sequence lets the
analyzer fall back to unoptimized channel switching.
Setting parameters:
<Order> AUTO | MANual
AUTO
Optimize the switching times for the channel order that is auto-
matically used with INIT:ALL (increasing order of channel
numbers).
MANual
Optimize the switching times for the channel order manually
specified using channel numbers <Ch1>, <Ch2>, ...
<Ch1>, <Ch2>, ... Can only and must be specified for MANual optimized channel
ordering. Defines the order in which the channels are measured.
To get the optimization to work, you have to sweep the channels
manually, and in the specified order: INIT<Ch1>,
INIT<Ch2>, ...
Example:
*RST;
*RST creates channel 1, trace 1, and diagram 1.
:INITiate1:CONTinuous OFF
enable single sweep mode
CALC2:PAR:SDEF 'Ch2Tr1', 'S11'
CALC3:PAR:SDEF 'Ch3Tr1', 'S11'
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
create additional channels 2, 3 and 4 with one trace each
DISP:WIND1:TRAC2:FEED 'CH2TR1'
DISP:WIND1:TRAC3:FEED 'CH3TR1'
DISP:WIND1:TRAC4:FEED 'CH4TR1'
assign these traces to diagram 1
:CONF:CHAN:MEAS:OPT AUTO; :INITiate1:IMMediate:
ALL
optimize the switching times for the AUTOmatic channel order
1,2,3,4, and restart the sweep in all channels
:CONF:CHAN:MEAS:OPT MAN, 2,3,1,4; :INIT2; :
INIT3; :INIT1; :INIT4
optimize the switching times for channel order 2,3,1,4 and
restart the sweeps in the same order
Usage:
Setting only
CONFigure:CHANnel<Ch>:MEASure[:STATe] <Boolean>
Enables or disables the sweep in channel no. <Ch>. This command can be used to
restrict the measurement in a subset of channels in order to optimize the measurement
speed.
