Electrical Pulse Mask and Output Level Characteristics
Specifications
Description
This test ensures the Electrical Transmitter output level and pulse shape
meet the required specifications. 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.
