Analog Pogo Pad Location

The pogo pads for the AWGs the Digitizers and the TIAs

are assigned in the following three parts. Here a list of

some of the abreviations used in the following three tables:

• DGND stands for digital ground.

• AGND stands for analog ground.

• FGND stands for floating ground, i.e. no connection to

any ground. These ones are kept for future expansion.

• A+/- (B+/-,C+...) stand for differential output lines

which are used as twisted pairs each to reduce noise.

• Sync clk runs a trigger signal and will be used for serial

inputs together with the .

• Sync data is thought to serve the timing generator via a

two wired system with serial input after future soft-

ware extensions will have been made.

• Status out marks whether a sampling or waveform

generating process is on or off.

• Pad # is the number of a pad within a pad block.
