The ACT6000 is an advanced communications tester for qualification and certification of symmetric copper pairs used for communications services up to 30Mhz for a variety of different applications and industries. Able to perform quick and easy “Single-Ended Line Tests" without the need for a second tester, the ACT6000 simplifies the testing of copper pairs for users. For other specific “End-to-End Line Tests" the ACT6000 can be used with another ACT6000 in order to carry out detailed advanced tests.
The ACT6000 is able to perform a number of different tests including:
Transmissive Qualification Tests
Metallic Qualification Tests
Telephone Signalling Tests
Widely used by companies in the Rail sector for data communications testing, Air Traffic for Voice and Data communications, Electricity suppliers for data and speech transport (Power Line Communications), Highway/Transport for data communications, and Telephone and Broadband Service providers for POTS and broadband testing.
Using the ASW-1 software option, users can perform automatic tests that perform a complete set of single ended electrical and transmissive tests to qualify the line for a specific service. Being able to perform single ended tests with the ACT6000 provides a significant advantage over other tests and testers, with no need for a remote tester or technician at the far end.
In addition to the basic electrical and transmission tests, S/N Ratio and maximum Bit-Rate estimations tests are added to the test sequence for ADSL, ADSL2+ and VDSL2 services.
The complete Single-Ended test sequence takes under 2 minutes with a test summary screen showing the results according to the international acceptability criteria and transmission masks (ETSI or ANSI).
The ACT6000 is able to perform real time transmissive measurements using a powerful spectrum analyser. Spectral analysis is possible from 200Hz to 6Mhz, or up to 30Mhz with the EBM30 Module. The real-time graphical capability of the spectrum analyser provides users with a quick and easy method of checking pairs for performance before deployment of services.
Using the High Impedance mode and non-intrusive probes, it is possible to perform PSD measurements to verify the spectrum and energy of any digital stream (i.e. to extrapolate the ADSL, ADSL2+ and VDSL2 profile).
By connecting the instrument in parallel with the active powered line it is possible to perform quick signal maps on the Main Distribution Frame or Street Cabinet without disturbing the underlying service. This mode of operation is ideal when users need to check if broadband services are present on pairs, and verify the service type and signal level.
The spectrum analyser capability of the ACT600 enables noise measurements on pairs, helping identify sources of noise that may affect performance, and helping to eliminate these.
When there are spikes of noise these can often be from sources outside of the pair under test, more uniformly spread noise tends to be caused from crosstalk and other interferers from with inside the pair/bundle.
As the impedance of pairs vary according to the length of the loop, the type of insulation and other factors, Return Loss Measurements provide the user with an indication of the quality of the pair under test, and potential problems due to signal degradation.
The ACT6000 provides a real time view of the insertion loss of pairs, with pass/fail masks displayed for the service type selected in the test setup.
Communications circuits are balanced circuits where each side of the pair should be equally balanced to ground, Any inbalance can introduce noise on to the circuit and can affect performance of the service running on that pair.
Users are able to view a real time view of the longitudinal balance of a pair and determine pass/fails using the masks displayed for the service type selected.
Using the ASW-1/II software option users can perform bidirectional End to End transmissive tests using two ACT6000 units. With one unit placed in slave mode technicians can control and carry out comprehensive line certifications from one end with the local ACT6000 controlling the remote unit in-band. When running DELT tests there are no length limits imposed on the tests being run.
With the optional Telephone/POTS module the ACT6000 can emulate a standard telephone, both making and receiving calls.
