ABSTRACT:
An instantaneous bit-error-rate meter provides an instantaneous, real-time eading of bit-error-rate for digital communications data. Bit-error pulses are input into the meter and are first filtered in a buffer stage to provide input impedance matching and desensitization to pulse variations in amplitude, rise-time and pulse-width. The bit-error pulses are transformed into trigger signals for a timing pulse generator. The timing pulse generator generates timing pulses for each transformed bit-error pulse, and is calibrated to generate timing pulses having a preselected pulse width corresponding to the baud rate of the communications data. An integrator generates a voltage from the timing pulses that is representative of the bit-error-rate as a function of the data transmission rate. The integrated voltage is then displayed on a meter to indicate the bit-error-rate.
