User Manual Compliance Test System 3.0
5.12 Replay Mode
The CTS 3.0 Software can be used to replay previously recorded test data. This replay can be
done on the same test system that was used to record the original data or on an altogether
different PC.
In order to replay a test, the data acquired during the test needs to be saved to a CTS native data
file. If the save data option is not enabled in the additional setup window for Harmonics, there is
no way to replay a test later. The Pass or Fail result of any run on the actual test system PC is
always logged however. If a different PC is used to play back data, the data files have to be
transferred to this PC first. The test data files are stored in the following directory:
C:\Program Files\California Instruments\CTS\Data_files
5.12.1 To play back test on the actual test system PC, proceed as follows:
1. From the Test Menu, select 'Replay an existing test'. This will bring up a table showing all
tests ever run on this system.
2. Select the test you want to replay by clicking on its row. If data for this test was stored and is
available, the Replay Test button at the bottom will be enabled.
3. Click on the Replay Test button to start the replay process. This will bring up a standard
Harmonics or Flicker test screen.
4. To start the replay process, click on the Start button. The data displayed will be taken from
the stored data files. The replay mode is indicated in the lower right corner on the status bar.
5. The buffer rate and speed at which data is replayed can be controlled using the various
settings in the Options menu. This may be required to adjust to the speed of the PC used.
6. The replay process can be halted at any time by clicking on the Stop button. This will stop
the data at the buffer number shown in the lower left corner.
7. Once stopped, the data can be stepped forward or backward at various rates using the VCR
style buttons in the lower left corner.
8. A test report can be printed from stored data in this mode. The actual date and time the data
was recorded will be shown on the report in addition the report print date and time.
5.12.2 To play back test on a different PC from the test system PC, proceed as follows:
1. If not already done, install a copy of the CTS 3.0 software on the other PC. When launched,
the absence of a data acquisition system will be detected and flagged. This is normal.
2. Transfer the data files to the PC used for replay, either using a network connection or disk.
3. From the File menu, select the Open Data File entry, This brings up the standard file open
dialog box.
4. Locate and select the file to be replayed. Harmonics files start with the letter H, flicker files
start with the letter F.
5. Click on the Open button to open the test data file. This will bring up the test window.
6. To start the replay process, click on the Start button. The data displayed will be taken from
the stored data files. The replay mode is indicated in the title of the CTS software.
7. The buffer rate and speed at which data is replayed can be controlled using the various
settings in the Options menu. This may be required to adjust to the speed of the PC used.
8. The replay process can be halted at any time by clicking on the Stop button. This will stop
the data at the buffer number shown in the lower left corner.
