Analyst ems+ft Overview

Overview
The CheckSum Analyst ems+ft extends the testing power of the Analyst ems with an integrated functional test subsystem that includes flexible stimulus, measurement and switching capabilities. It combines in-circuit test (ICT) with power-up functional test to provide high fault coverage in a single, low-cost platform that can be customized by the user to fit a variety of test requirements.

Including industry-unique features such as 250VAC switching and a fully integrated DMM, function generator and counter-timer, as well as available relay switching in 50 point increments, the Analyst ems+ft meets a broad range of functional test requirements from straightforward power up “board alive” tests to extensive functional test sequences.

A typical test sequence on the Analyst ems+ft would proceed as follows:

Power-off in-circuit test (ICT). Typically, test programs are written such that the test is aborted if any power-off faults are detected.
Apply board power and check critical voltage points including behavior of powered components such as operational amplifiers.
Perform more extensive functional testing such as checking input/output parameters.
Solid-state switching in 200-point increments and 50-point relay switch matrix cards may be mixed in any combination.

Circuits with voltages up to about ±12V will typically employ solid-state switching and voltages up to 250Vp-p are accommodated by relay switching. When greater than 40 volts is present at the UUT during test, the test fixture should be designed with safety shielding and operator interlocks to help prevent the operator from coming in contact with the signals.

In most cases functional test can be performed using the same test fixture as the in-circuit test so that minimal time is spent transferring, loading and unloading the UUT.

The Analyst ems+ft includes an additional 19 inch rack space, allowing addition of off-the-shelf measurement/stimulus instruments or programmable power supplies to meet special requirements.
