Multiple Readings with Initial Delay
Objective/Actions
To manually trigger a batch of 25 readings with 5 second intervals starting 15 seconds after
is pushed:
1. Enter the commands below.
2. Push
to start the 15-second delay.
Example
Result/Comments
TRIGger:RESet
ARM:LAYer1:DELay:AUTO OFF
Reset the trigger system to defaults
ARM:LAYer1:DELay 15
Trigger subsystem waits for 15 seconds
before entering the trigger layer
RIGger:SOURce TIMer
Trigger on the timer
TRIGger:TIMer 5
Set the timer to 5 seconds
TRIGger:COUNt 25
Take 25 readings before reverting to the Idle
state
TRIGger:DELay:AUTO OFF
Turn auto delay off
TRIGGER:DELay 0
Set Delay to 0.000
DIGITIZE with External Trigger Using Trigger Dividing
Objective/Actions
Aperture required = 6 µs. Use 10 MHz off-air reference clock divided by 100 to yield trigger
interval of 10 µs to capture 2000 samples.
Example
Result/Comments
:FUNC "DIGitize:VOLTage"
Select the digitize function
:DIGitize:VOLTage:RANGe 1
1 V range
:DIGitize:APERture 6E-6
Aperture = 6 µs
TRIGger:RESet
Reset the trigger system to defaults
TRIGGER:SOURce EXTernal
Default setting is TTL, NEGative edge
TRIGGER:COUNT 2000
2000 samples to be captured
TRIGGER:ECOunt 100
One acquisition for every 100 trigger edges
TRIGger:DELay:AUTO OFF
Turn auto delay off
TRIGGER:DELay 0
Set Delay to 0.000
READ?
Starts the capture and returns the data
Note
The first acquisition starts (ECount -
1) * trigger edge period after the
:READ? command is sent {(100 - 1) *
10 µs = 990 µs}.
