Measured-value trigger
Storage of measured value alternatively through exter-
nal or internal trigger (see User's Manual for Application
Development)
External: Signal via trigger input (front and/
or rear panel)
Software command (via Ethernet)
Synchronous operation
(via SynClk + PTM)
Internal: Timer
Synchronous operation (SynClk +
PTM are generated internally)
