Hybrid Connection
(per Driver/Receiver board)
Connects Front Panel pin to any channel via
the Pin Driver electronics. (User must disable
the drive enabled to the channel.)
~40 Ω series impedance, ~3 MHz bandwidth
Hybrid Channel Relay Connection
(per channel)
Connects I/O pin to the Hybrid channel pin
(5 ms connection latency for Break Before

I/O Min/Max Levels
The I/O level minimum and maximum values are determined by the V+ and
V- bias voltage levels. The following table lists the min and max levels based
on the V+ and V- level:
