External Digital Modulation using Input Trigger Connector
External digital modulation uses a TTL-level signal. Apply this signal to the
Input Trigger connector on the rear panel of your mainframe. For
information on external digital modulation, see
on page 156.
A maximum of 5 V can be applied as an external voltage to the Input
Trigger connector.
Take care not to use the Trigger Output connector or the Remote
Interlock connector for modulation. Do not apply an external voltage to
these connectors.
