Specification
NOTE The Rates available are dependent on the HP 37718A/19A option
Description
This test ensures the transmitter output level and pulse shape meet the
required specifications at all PDH/DSn rates. The Transmitter output is
connected to an Oscilloscope and the waveshape compared with the
predefined masks stored in the Oscilloscope memory. The signal levels
are also measured using the Oscilloscope.
