Synchronizing Acquisitions

 

Synchronizing with a Single-Shot Device Under Test (DUT)

The examples in 

"Blocking Synchronization" 

on page 781 and 

"Polling 

Synchronization With Timeout" 

on page 782 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" 

on 

page 782 with the addition of checking for the armed event status.

' Synchronizing single-shot acquisition using polling.

Option Explicit

Public myMgr As VisaComLib.ResourceManager

Public myScope As VisaComLib.FormattedIO488

Public varQueryResult As Variant

Public strQueryResult As String

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Sub Main()

On Error GoTo VisaComError

' Create the VISA COM I/O resource.

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.

N O T E

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.
