To use the trigger output
1
Connect the trigger output to the instrument or device you want to
trigger.
The trigger output is labeled “Trigger out” on the front panel of the
HP 54620A/C. Usually, you will connect this to the external trigger input of
another instrument, using a BNC cable. Output signal swings are 0 to 2.7 V at
an output impedance of 50
Ω
.
2
Set the desired trigger condition for the HP 54620A/C.
See “To define an edge trigger,” “To define a pattern trigger,” or “To define
an advanced trigger.”
3
Set the desired trigger condition for the external trigger input of the
target instrument.
This usually consists of setting trigger level and edge, but may include other
parameters. See the manual for the instrument in question.
4
Start an acquisition on the HP 54620A/C by pressing
Run
,
Single
, or
Autostore
.
As the HP 54620A/C finds its trigger condition, it pulses the trigger output
signal.
Stop Acquisition to Increase Trigger Output Rate
While in Run mode, the HP 54620A/C can only generate trigger outputs as fast as
it can acquire the data and update the waveform display. This is normally fast
enough to trigger digital oscilloscopes. However, it is not fast enough to ensure
a usable display for analog oscilloscopes. To obtain a faster trigger for these
instruments, stop acquisition on the HP 54620A/C by pressing the Stop key. The
HP 54620A/C will continue to recognize its trigger condition and will drive the
trigger output, but does not have the overhead of data capture display updates.
Thus, the trigger output is generated at a much higher rate. The trigger status is
still valid.
