BNC 670C - Auxiliary Channels; Marker Output; Trigger In

Model 670C Berkeley Nucleonics Corp. 25 of 96
The Marker Out is a digital output channel that generates a pulse related to the analog waveform. Its
impedance is 50 Ohm and the output voltage amplitude ranges from 1 V to 2.5 V into 50 Ohm load.
The Marker Out generates a digital pulse synchronous with the waveform depending on the Run Mode.
To set the Marker Out parameters refer to the Marker Settings.
The connector type is a standard BNC.

The Trigger In allows to control the generation by an external signal source. It has a selectable
impedance of 1kOhm or 50Ohm. To know how to set the trigger parameters or the Run Mode refer to
the paragraph “Trigger”. In Continuous mode the Trigger In doesn’t have any effect.
