Comments • The available sources are:
– EXTernal: The Agilent E1445A’s front panel “Stop Trig/FSK/Gate In” BNC
connector.
– TTLTrg0 through TTLTrg7: The VXIbus TTL trigger lines.
• The front panel’s “Stop Trig/FSK/Gate In” BNC is a three-use connector; for
FSK control, as a stop trigger source, or as a sample gate source. Only one of
these uses may be active at any time.
• If a VXIbus TTLTrg trigger line is used for FSK control, then no TTLTrg trigger
lines can be used as a stop trigger source or as a sample gate source.
