Rear Panel Connectors and Pin Designations

This instrument can deliver a lethal electric shock.
to avoid electric shock, personal injury, or death, never touch any lead
or terminal unless you are absolutely certain that no dangerous voltage
is present.

Rear Inputs

For details of rear input terminals see Figure 2-1

External Trigger Input

This co-axial BNC socket can be used to trigger a measurement when external triggers
are enabled.
The single pin is pulled up internally to +5V, and requires a negative-going TTL edge to
initiate the reading.

IEEE 488 Input/Output

The IEEE 488 input/output is a 24-way Amphenol connector which is directly
compatible with the IEEE 488 interface and the IEC 625 Bus.
Note that the Bus Address is set from the front panel. See Chapter 4 for more information
about the IEEE 488 connector and remote operations.
