User Manual Compliance Test System 3.0

1.2.3 PC Based Data Acquisition System (updated for new PCI data acquisition)

All measurements required for IEC testing are performed by the data acquisition system that

resides on the user’s PC. The measurement card needs to be installed in an available slot and

the software needs to be installed. All signal connections between the PC and the PACS unit are

made with a single 37-pin cable supplied with the system.

The following data acquisition cards are supported by the CTS 3.0 software:

CI400PCI PCI card NI 6032/4E. No longer provided on new system shipments but

still supported by CTS30 software revision 3.2.X

CI401PCI PCI card Exacq Technologies CM2110 PCI A/D card, 250 Ks/sec for

single phase systems (P/N 250803)

CI403PCI PCI card Exacq Technologies CM2210 PCI A/D card, 1 Ms/sec for three

phase systems (P/N 250797)

All CTS systems are delivered with a PCI bus A/D card. Older systems may use the –ISA or -MC

cards. The CTS 3.0 software installation differs for each of these legacy A/D cards. For new

installations, only the PCI card should be used however.

The data acquisition system samples all voltage and current channels at a high sampling rate

and provides the data to the CTS 3.0 software for further processing. The PACS provides a

single voltage input channel and three current input channels for each phase, to the PC. This

allows for current range changing on the fly. There is no need for the user to select a current

range as the software automatically uses the most suitable range available for the current signal.

1.2.4 CTS 3.0 Software Functions

The CTS 3.0 software application supports IEC 61000-3-2 and IEC 61000-3-3 compliance testing

requirements using an intuitive graphical user-interface from which you can:

• Set up and run compliance-level tests. The setting up of many IEC details is facilitated

through the use of embedded standards expertise.

• Collect real-time test data from the CTS System.

• Display and monitor real-time test results.

• Save test results to disk for analysis using other programs.

• Replay previously recorded test data and single step through the data frame by frame.

• Print reports and graphs in MS Word™ formats.

1.2.5 AC Source GUI Functions

If the CTS system in use was supplied with an AC source, it also includes an AC source control

software package. This Graphical User Interface program can be used to control the AC source

from the same PC using either the RS232C or IEEE-488 interface. An IEEE-488 interface is not

included with the CTS system. The PC must have an available RS232C port to use the RS232C

control interface to the source.

In the absence of a suitable interface, the user can operate the AC source from the front panel.

This does not affect the ability to run harmonics and flicker tests. It does however preclude the

use of the IEC 61000-4 immunity tests, which are only available through the CIGUI32

CIGuiSII AC source control program.

IEC 61000-4 tests are pre-compliance only on the 1251-CTS.
