The :CALibrate commands are used to control the latency from the
M8131A digitizer to the M8121A AWG. This set of commands should be
used only when controlling both instruments. The end effect is that the
delay from the analog input of the digitizer to the analog output of the
AWG is a fixed latency for a given setup. The calibration procedure must
be run upon a change in conditions, such as a disruption to the data flow
over ODI, change in cables, or a change in clock source.
:CALibrate:SYNC:INPut:LEVel
Command :CAL:SYNC:INP:LEV <level>
Query :CAL:SYNC:INP:LEV?
Parameters <level>|MINimum|MAXimum|DEFault
None
Description Set or query the Sync input threshold in Volts.
The Sync Input is used with the M8131A digitizer to calibrate a
deterministic latency from analog input to analog output.
Examples :CALibrate:SYNC:INPut:LEVel 0.4
:CALibrate:LATency:LCMP
Command :CALibrate:LATency:LCMP <lcmp_value>
Parameters <lcmp_value>
None
Description Lowest common multiplier between the internal clocks of the M8131A and
M8121A. Use value of 5 when operating with a M8131A digitizer.
Examples :CALibrate:LATency:LCMP 5
