and, therefore, use the same SYNC CLK, SYNC DATA, and STATUS2 pins.
Waveform Digitizers
The High Resolution Digitizer (WDB), High Speed Digitizer (WDA),
100MHz Digitizer (WDG), and 1GHz Digitizer (WDD) can measure
an analog waveform at one of 8 single-ended or 4 differential
channels.
The 20MHz Digitizer (WDE) has two digitizer cores. A WDE
digitizer core can measure an analog waveform at one of 4 single-
ended or 2 differential channels.
The Dual High Speed Sampler (SPA) has two sampler cores. A SPA
sampler core can measure an analog waveform at one of 2 single-
ended channels.
The 3GHz Sampler (SPB) has two sampler cores. A SPB sampler
core can measure an analog waveform at one of 2 single-ended
channels or 1 differential channel.
In addition, to control the execution of each digitizer or sampler,
the trigger line SYNC CLK is used:

A WDE, SPA, or SPB module contains two cores. Both cores in the module operate synchronously
SYNC DATA: Currently not used.
DGND: Digital ground on the digitizer.
AGND: Analog ground on the digitizer.
FGND: Floating ground. Not connected to any ground. For future expansion.
