Characteristic Description
AC, DC, Noise Reject, High Frequency Reject, Low Frequency R ejectTrigger Coupling
The External Trigger path does not have a DC blocking capacitor ahead of the trigger input circuit. The
rolloff associated with AC coupling happens after the input circuit. When attempting to trigger on an AC
signal that has a DC offset, care must be used to avoid overloading the input of the External Trigger
circuit. For signals that have a large DC offset, using Channel 1 or Channel 2 (and Channel 3 or C hannel
4 for the TDS20X4B) with AC coupling is preferred.
Trigger Slope
Rising Edge, Falling Edge
Measurement Style A) The minimum signal levels for achieving stable frequency indication on the Trigger
Frequency C ounter 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.
