The Agilent/Keysight 1645A is a Data Error Analyzer engineered to isolate faults within data communication links through six concurrent measurements. It maintains synchronization automatically, even during signal dropouts, enabling unattended operation across extended test sequences.
The instrument delivers direct LED readouts for bit-error and block-error rate testing with auto-ranging capability, eliminating manual calculation overhead. Jitter and total peak distortion measurements characterize signal integrity by quantifying combined jitter and bias effects. The analyzer counts carrier loss events, signal dropouts, and clock slips resulting from phase hits or modem synchronization failures. Data error skew assessment rounds out its diagnostic toolkit for comprehensive link characterization.
