DIGITAL TRANSMISSION MEASURING INSTRUMENTS

GPIB

The MP1763B is used in combination with the MP1764A

Error Detector.

The amplitude of the clock and data signals can be varied from 0.25

to 2 Vp-p while the offset can be adjusted to within ±2 V so that the

amplitude and the offset margin can be measured. The clock has a

variable delay function so that time-dependent characteristics or

phase margins of the input clock and data can be measured. An M

series pseudorandom pattern representative of actual conditions or

a programmable pattern can be selected as cell data.

In addition, a 3.5 inch floppy disk drive is built in for storing preset

data, enabling rapid measurements to be performed by simply press-

ing a key. A GPIB function is provided, enabling automatic or remote

measurement via an external controller.

The MP1763B is a pulse pattern generator ideal for research and

development of high-speed logic, ICs, and digital systems.

Features

•High quality waveform

•Low FM/PM-noise clock generator

•8 Mbit programmable pattern corresponding to six frames of STM-

64/STS-192

•Generates PRBS patterns with bit length from 2

–1 to 2

–1 bits

•Complementary outputs of both data and clock

•The amplitudes and offsets of all 8 data outputs that have 1/8

speed of fundamental clock signal can be set
