Edge trigger
Trigger modes Auto, Normal, Single sequence
Trigger coupling (analog
channels)
AC, DC, Noise Reject, High Freq Reject, Low Freq Reject
The Aun In path does not have a DC blocking capacitor ahead of
the trigger input circuit. The roll off associated with AC coupling
happens after the input circuit. When attempting to trigger on an
AC signal that has a DC offset, use care to avoid overloading the
input of the Aux In circuit. For signals that have a large DC offset,
using Channel 1 or Channel 2 with AC coupling is preferred.

Measurement Style A: The minimum signal levels for achieving stable frequency indication on the
Trigger Frequency Counter within 1% of correct indication.
Measurement Style B: Section 4 10.2 in IEEE Std. #1057. The minimum signal levels required for
stable edge triggering of an acquisition when the trigger Source is DC coupled.
