Pattern
Characteristics
Patterns are defined by the following parameters:
 Internal or external pattern source
 PRBS patterns and user defined patterns
 NRZ formatting and Arbitrary Bit Waveform
 Pattern Mode - On/Off
 Patterns are also characterized by 2, 3 or 4 different levels per bit
 Adjustable loop offset, allowing emulation of initialization preamble
and looped test pattern
 External pattern source allows re-timing and re-shaping of externally
provided data stream
Sine Wave
Characteristics
A sine wave is defined by the following parameters:
 Amplitude/Offset or High/Low Level
 Period or Frequency
 Delay in seconds
 Delay in percent of period
 Delay as phase in degree
 Polarity
 Source Impedance
 Load Impedance
Square Wave
Characteristics
A square wave is defined by the following parameters:
 Amplitude/Offset or High-Level/Low-Level
 Period or Frequency
 Duty Cycle
 Delay in seconds
 Delay as percentage of the period
 Delay as phase in degree
 Polarity
 Source Impedance
 Load Impedance
The instrument will always generate the fastest possible transition times
when generating square waves.
