Automatic jitter measurements

This section provides specifications for automatic jitter measurements.
Maximum Tolerable Jitter (MTJ)
A group of up to 20 user-specified jitter frequencies (scan frequencies) can be defined.
A set of pre-defined masks per applicable standards is also provided.
Fast Maximum Tolerable Jitter (Fast MTJ)
A group of up 20 user-specified frequencies (scan frequencies) can be defined. A set
of pre-defined masks per applicable standards is also provided.
Jitter Transfer Function (JTF) measurement
A group of up to 20 user
set of pre-defined masks per applicable standards is also provided.
