Evaluation of the agilent 3458A time jitter performance

The paper describes the mechanism of Agilent 3458A sampling time jitter present when external triggering is used at synchronous two channel sampling. Based on measurements it is shown that the master DMM adds approximately 3.2 ns of its own time jitter while triggering the slave DMM and that the effective time jitter for externally triggered DMM remains at 7 ns, well below ±50 ns maximum jitter as specified by manufacturer.
