AT5600 Test Specs, Models and Quotes

The AT5600 is capable of performing over 40 different test types.
In addition to this you can also write test programs (basically a pre-programmed sequence of tests) with up to 150 different steps.
This extends the scope from the AT3600, which only allowed 65 different steps.

The following page summarizes the tests available for the AT5600 tester, and indicates where and why they might be used. A complete description of each test, its allowed signal levels and measurement accuracy can be found in the user manual.

The tester is available to purchase in one of two versions
AT5600 GOLD - all the original 44 tests are enabled at point of shipment
AT5600 STANDARD - you choose which 14 tests you would like enabled in the unit.

Each unit is supplied with a traceable calibration certificate, Ethernet lead, USB lead, Legacy RS232 Editor and RS232 Server leads, touch screen stylus, screen protectors and an interlock override plug.

Please Note: The unit does not ship with any fixtures, as many customers already have their own fixtures. Please see our Fixturing and connectors page for more details. Please contact us if you need advice.

Additional tests can be purchased at any later date, and easily added to the tester by entering a simple keycode via the front panel. All tests are calibrated and tested at point of sale, even if not purchased initially with the unit. You can get instant quotes and order individual tests (also for AT3600 +ATi too) on this page.
