Acq Start

-- The initial position of holdoff is the first-time point satisfying the trigger condition. In the

example above, each holdoff starts from the first rising edge of the pulse sequence.

Last Trig Time

--The initial position of holdoff is the time of the last trigger. In the example above, the

last trigger position is at the second rising edge of the pulse sequence and the second holdoff starts

from that point.

13.8 Trigger Coupling

The coupling setting of a trigger is only valid when the trigger source is C1~C8, EXT, or EXT/5.

 DC: All of the signal’s frequency components are coupled to the trigger circuit for high-frequency

bursts or where the use of AC coupling would shift the effective trigger level.

 AC: The signal is capacitively coupled. DC levels are rejected. See the datasheet for details of the

cut-off frequency.

 HFR: Signals are DC coupled to the trigger circuit and a low-pass filter network attenuates high

frequencies (used for triggering on low frequencies). See the datasheet for details of the cut-off

frequency.

 LFR: The signal is coupled through a capacitive high-pass filter network, DC is rejected and low

frequencies are attenuated. For stable triggering on medium to high-frequency signals. See the

datasheet for details of the cut-off frequency.
