The Agilent HP 1645A Data Error Analyzer quickly isolates data communications link problems through six simultaneous measurements. During tests, it can be left totally unattended because it automatically maintains synchronization even in the presence of dropouts. The 1645A can be equipped with a printer for hard-copy, permanent recordings of long tests. Bit-error and block-error rate tests are autoranged and displayed directly on a LED readout, there is no need to perform any calculation. Additionally, the 1645A measures jitter or total peak distortion (the sum effect of jitter and bias), counts the number of times carrier loss or dropouts occur, measures data-error skew and counts the number of clock slips resulting from phase hits on the link or modem sync problems. With all these measurements made during the same test interval, you’ll know precisely what is causing your problems in modems, data channels, complete communications systems.
