A.4.7 Synchronizing Measurements
Some sensors (e.g. R&S
NRP-Z81/85/86) are able to generate signals on the (exter-
nal) trigger bus, when an internal trigger was detected. This allows for synchronized
measurements with multiple sensors.
One sensor has to be configured as trigger master (:TRIG:SOUR INT; :TRIG:MAST
ON), while all other sensors are slaves with external trigger source (:TRIG:SOUR
EXT).
