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.
