GN4070 Binary marker HV card
The GN4070 binary marker HV card is a combined electrical and
optical binary marker input card. It enables to record up to 32
electrical and eight optical binary input channels (marker
channels) with up to 1 MS/s per channel. The optical isolated
binary makers are specifically suited for the medium/high voltage
market. A fiber optic isolated output is provided to present an REC
signal that can be used to drive an external instrument. The fiber
optic inputs and the fiber optic REC output allow for a tight
integration with the BE3200 high
-
definition test sequencer.
In addition, software control can assign nine binary input channels
to provide three channels of counter/timer functionality.
The counter/timer functionality includes:
l
64 bit general purpose up/down counter
l
Frequency/RPM counter
l
Quadrature/position measurements
The counter/timer functionality uses up to 3 event bits per channel.
These event bits also keep their original functionality. For
example, a quadrature encoder rotation is recorded, while at the
same time the quadrature output signals are recorded separately.
