Standard Masks
The Infiniium Option 100 and the E2625A Telecommunications Mask Template Kit disk contains standard masks used by the telecommunications and data communications industries. These are the masks you can load into the oscilloscope to test your waveform’s compliance against industry standards.
To use any of these masks, follow the procedures in chapter 2.
