Chapter 5: Manual Testing
The PeRT 3 Eagle supports the ability to conduct quick manual tests in addition to running
preprogrammed test scripts supplied with the system or developed by the user.
Manual testing is controlled by the System Control Ribbon located at the top of the PeRT 3
main application window. Manual testing is a good introduction to how to develop test
scripts, since the steps followed are largely the same.
To set up a test, work from left to right across the panels in the Main tab, starting with the
PeRT
3 panel to select the system to be used, then the Configuration panel to select the
protocol and data rate, followed by the DUT Initialization panel to specify the DUT setup
and initialization sequences, and finally to the DUT Status panel to connect to the DUT.
System Control Ribbon - Main Tab
If the Main tab along the top of the System Control Ribbon is clicked, the ribbon will show
a series of five panels, as follows:
Master Controls
The Master Controls panel allows the user to
specify the test to be run. If a manual test is
desired, select Manual Test in the drop-down
menu (this is the first item on the list). This
allows the user to Start (don’t record), Start
(record results), Pause or Suspend the test,
to Connect or Disconnect from the DUT, and
indicates which channels are being tested
through the "1", "2", "3" and "4" which function
as on-screen LEDs to show which channels are
active. Also, the panel shows the status of bit
errors encountered on each of the channels while the test is running and allows the user
to deliberately inject a bit error (into all active channels) by clicking the button on the lower
right.
Note: The difference between Start (don’t record) and Start (record
results) is that while running (but not recording results) the system
allows the user to change any of the signal or jitter settings while a
test is running. This is useful during initial test development to
quickly determine how the device under test behaves under different
conditions. If results are being recorded, the user may not change
test settings without first stopping the test.
