There are two BNC connectors on the rear panel of your instrument.
These are the Trigger Out and the Trigger In connectors.
The N7747A and N7748A have a front panel BNC connector for each
channel. These are for analog output signals and provide a voltage
proportional to the input signal power in mW. The voltage is in the range
0-2 V and 1 V corresponds to the value of the currently selected power
range. For example, when using the -10 dBm range, a 100 µW optical
power will give 1 V analog output.
The Trigger In is a TTL input. A maximum of 5 V can be applied as an external voltage
to this input connector.
The Trigger Output is a TTL output. Do not apply an external voltage to this
connector.
No external voltage should be applied to the analog output connectors of the
N7747A and N7748A.
