PPG1600, PPG3000, & PPG3200 Pattern Generator User Manual
Data and Clock front panel RF connectors are 2.92 mm (K type) for the
PPG1600 and PPG3000 series. Data and clock connectors are 2.4 mm for the
PPG3200 series. All other front panel RF connections are SMA.

These are the primary outputs from the unit. The outputs can be used single-ended
or differentially. Data pattern, levels and timing can be controlled manually or
remotely.
These differential outputs provide a timing reference for viewing the data signals.
The output amplitudes are fixed. Trigger options are PATTERN or CLOCK/N.
When using a pattern trigger, the trigger corresponds to the beginning of a pattern.
The pattern trigger mode can be used with user-defined or PRBS data. For the
CLOCK/N trigger mode, the clock frequency is reduced by a factor of N where
the value N is required to be a multiple of 64.
The clock output reflects the data rate; there is one full clock cycle per bit of data.
The clock output is AC coupled and the amplitude is fixed. The internal clock
actually operates over a range of 15 GHz to 30 GHz (PPG3000 series) or 16 GHz
to 32 Ghz (PPG1600 and PPG3200 series). When data rates <15 Gb/s (PPG1600
and PPG3000 series) or <16 GHz (PPG3200 series) are used, the internal clock
will operate at a multiple of the data rate and bit-stretching is used to produce data
at the specified rate. A built-in clock divider can be used to divide the internal
clock before it is sent to the clock output (divisors of 1, 2, 4, 8, 16).
This is the input used to supply an external clock. Clock frequency is restricted
to a range of 15 GHz to 30 GHz (PPG3000 series) or 16 GHz to 32 GHz
(PPG3200 series)—same as the range of the internal clock source.
NOTE.
The external clock input is not available for the PPG1600 series.
