trigger event and then stops. In Envelope, Average, or WfmDB mode, the instrument
makes the specified number of acquisitions to complete the averaging or enveloping
task, and then stops.
The Acquisition Status lights indicate the state of the acquisition:
ƒ When TRIG’D is on, the instrument has recognized a valid trigger and is
filling the posttrigger portion of the waveform.
ƒ When READY is on, the instrument can accept a valid trigger event and is
waiting for the trigger event to occur.
ƒ When ARM is on, the instrument is filling the pretrigger portion of the
waveform record.
ƒ When TRIG’D and READY are both on, the instrument has recognized a valid
trigger and is waiting for a delayed trigger. When the instrument recognizes a
delayed trigger, it will fill in the posttrigger portion of the waveform.
ƒ When ARM, TRIG’D, and READY are not on, the acquisitions have stopped.
