Description

This test ensures the transmitter output level and pulse shape meet the required spec-
ifications at E1,E3,DS1 and DS3 rates. The Transmitter output is connected to an os-
cilloscope and the waveshape compared with the predefined masks stored in the
oscilloscope memory. The signal levels are also measured using the oscilloscope.
