Query: Indicates whether calibration is required or not.
Based on hexadecimal bit value, it provides following information:
0x00000001: Front end calibration is required
0x00000002: Digitizers delay matching is required
0x00000004: Digitizers gain matching is required
0x00000008: Trigger level calibration is required
0xFFFFFFFF(-1): All of above calibrations are required

Description
Resets any accumulated average data or persistence data for channel waveforms (C1..C4). Valid only
when one or more channels have waveform averaging or persistence enabled in their pre-processing
settings. Note that an average may be reset on an individual basis using
app.Acquisition.Cx.ClearSweeps control.
ClearSweeps Action
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Clear accumulated sweeps for channels C1...C4
app.Acquisition.ClearSweeps
' Clear accumulated sweeps for only C1
app.Acquisition.C1.ClearSweeps
Example
Description
Action/Query. Takes a single acquisition. The first of the two arguments specifies a timeout; the
second, which is optional, specifies whether or not to force a trigger when the timeout occurs.
Evaluates to True if a trigger occurred, or False if a timeout occurred.
Acquire([in] double timeoutSeconds, [in] long bForceTriggerOnTimeout) Method
' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")
' Start an acquisition, wait for up to 5 seconds for a trigger
' event, force a software trigger if a hardware trigger is not
' detected before the 5 second timeout expires.
triggerDetected = app.Acquisition.Acquire(5, true)

CHANNELS app.Acquisition.Channels
This group of variables controls the acquisition channels C1, C2, C3 and C4.
Names of the form app.Acquisition.Channels.xxxx are aliases of simpler names which are described in the section of the
