Synchronizing Acquisitions

 

Example: Blocking and Polling Synchronization

# -*- coding: utf-8 -*-

# ********************************************************************

# This script using the Python language (http://www.python.org/) and

# the PyVISA package (http://pyvisa.readthedocs.org/) shows the two

# best synchronization methods for InfiniiVision oscilloscopes.

# Benefits and drawbacks of each method are described.

No error

# handling is provided except in the actual synchronization methods.

# IO timeout in milliseconds

TIME_TO_TRIGGER = 10

# Time in seconds

# --------------------------------------------------------------------

# This is the time until the FIRST trigger event.

#

# While the script calculates a general timeout for the given setup,

# it cannot know when a trigger event will occur.

Thus, you must

# still set this value.

#

# This time is in addition to the calculated minimum timeout... so, if

# an oscilloscope might take say, 1 us to arm and acquire data, the

# signal might take 100 seconds before it occurs... this accounts for

# that.

#

# The SCOPE_ACQUISITION_TIME_OUT calculation pads this by 1.1.

# --------------------------------------------------------------------

TIME_BETWEEN_TRIGGERS = 0.025

# Time in seconds - for Average,

# Segmented, and Equivalent Time modes, else set to 0

# --------------------------------------------------------------------

# In Average, Segmented, and Equivalent Time modes, the oscilloscope

# makes repeated acquisitions.

This is similar to the above

# TIME_TO_TRIGGER, but it is the time BETWEEN triggers.

For example,

# it might take 10 seconds for the first trigger event, and then they

# might start occurring regularly at say, 1 ms intervals.

In that

# scenario, 15 seconds (a conservative number for 10s) would be good

# for TIME_TO_TRIGGER, and 2 ms (again conservative) would be good for

# TIME_BETWEEN_TRIGGERS.

#

# The default in this sample script is 0.025 seconds.

This is to make

# the sample work for the LINE trigger used in this script when the
