Electrical Telecom Pulse Mask Test Software

Introduction

ET-PMT is a software package that measures pulse mask compliance of electrical telecommunications
signals. Pulse mask testing consists of acquiring the given signal in an oscilloscope and comparing the
voltage vs. time waveform to a standard mask. The mask defines regions in V,t space where a compliant
signal must remain.

Below is an example of an ET-PMT pulse mask:

In cases where there are alignment criteria, such as a positive-going or negative-going pulse, the tests
include settings to define these criteria, and the ET-PMT software will automatically find only those pulses.

Standards Supported

The ET-PMT package supports the following ANSI and ITU standards.

ANSI T1 ITU-T

DS1 E1 (twisted pair)

DS3 E1 (coax)

STS-1 E2

STS-3E E3

---- E4

---- STM-1E

In addition to these standards, It is also possible to define modified or custom pulse mask tests.
