be triggered by external events. The trigger level can be set between -
5V and +5 V, thus supports a variety of logic level signals.

Multi I/O
The rear-panel BNC connector is a programmable analog output is
available for connection to an external chart recorder or other device.
The output voltage range is unipolar or bipolar 10 volts. The output
produces a voltage proportional to signal level, or a logic level status
voltage for signaling when the RF power is above or below preset “alarm limit”
thresholds. Recorder output parameters can be configured through the menu. The
connector will be used in the future for special instrument functions.
