Lesson 2 – Addressing the Analog Modules

Arbitrary Waveform Generator (AWG)
The High Resolution AWG (WGA), High Speed AWG (WGB) and
500M AWG (WGD) can generate a waveform at one of 8 single-
ended or 4 differential channels.
The 30M AWG (WGE) has two AWG cores. A WGE AWG core can
generate a waveform at one of 4 single-ended or 2 differential
channels.
The Ultra High Speed AWG (WGC) can generate a waveform at one
of 4 single-ended or 2 differential channels.
The 4.1G AWG (WGF) can generate a waveform at 4 differential
channels.
To control the execution of each AWG, the trigger line SYNC CLK
or TRIGGER is used.
SYNC DATA: Currently not used.
DGND: Digital ground on the AWG.
AGND: Analog ground on the AWG.
FGND: Floating ground. Not connected to any ground. For future expansion.
For the AWGs except WGC and WGF, the A-, B-, C-, and D- pins
can be used to generate a single-ended signal (non-inverted signal).

a
The ground of the signal generated by the WGF is in common with the digital ground,
in contrast to the other analog modules.
b
A WGE module contains two AWG cores that share the SYNC CLK, SYNC DATA, and
STATUS2 pins.
c
For WGC, installing AWG core 2 (AWG instrument 2) is optional. The function of the
WGC pins differs from that of the other AWGs. Instead of STATUS2 or reserved
(STATUS1), a “Marker” states whether a waveform generating process is on or off.
