The timing and state sampling speeds as described in the 16517A /
16518A are all in terms of the digital signal acquisition.

Timing Modes:

The 16517A/18A has two timing modes. In full-channel timing mode, data
is sampled at up to 2 GHz. In half-channel timing mode, data is
sampled at 4 GHz.

Synchronous State Mode:

In the full-channel state mode, a synchronous external clock running
at speeds up to 1 GHz can be used as the sample clock. In addition,
the sample point can be offset to ensure a sample where you know data
is valid.

Not only can you sample at the external clock transitions, but you can
set the analyzer to oversample, in powers of two, up to 32x, or, up to
a maximum of 2 GHz sample rate. Each point of oversampling is
precisely distributed evenly within the external clock period.
