Synchronizing Acquisitions
Synchronizing with a Single-Shot Device Under Test (DUT)
The examples in
on page 1268 assume the DUT is continually
running and therefore the oscilloscope will have more than one opportunity to
trigger. With a single shot DUT, there is only one opportunity for the oscilloscope
to trigger, so it is necessary for the oscilloscope to be armed and ready before the
DUT is enabled.
This example is the same
"Polling Synchronization With Timeout"
with the addition of checking for the armed event status.

Set myMgr = New VisaComLib.ResourceManager
Set myScope = New VisaComLib.FormattedIO488
Set myScope.IO = myMgr.Open("TCPIP0::130.29.69.12::inst0::INSTR")
myScope.IO.Clear
' Clear the interface.
' Set up.

' Set up the trigger and horizontal scale.
myScope.WriteString ":TRIGger:MODE EDGE"
myScope.WriteString ":TRIGger:EDGE:LEVel 2"
myScope.WriteString ":TIMebase:SCALe 5e-8"
' Stop acquisitions and wait for the operation to complete.
myScope.WriteString ":STOP"
myScope.WriteString "*OPC?"
strQueryResult = myScope.ReadString
' Acquire.
NOTE
The blocking :DIGitize command cannot be used for a single shot DUT because once the
:DIGitize command is issued, the oscilloscope is blocked from any further commands until the
acquisition is complete.
