Chapter 5 Troubleshooting
The internal structure of the generator consists of the main board, channel
board, power supply board, key and LCD board, and interface board. They are
linked through cables or connectors. This chapter explains the main
troubleshooting procedures for these boards (mainly main board and channel
board) by measuring the corresponding test points and checking the signals of
connectors on them, thus to help in determining the reason for the failure that
has been encountered while operating the SDG2000X series arbitrary
waveform generator.
ESD Precautions
While performing any internal test of the generator, please refer to the following
precautions to avoid damages to its internal modules or components resulting
from ESD.
Handle circuit boards by their edges as much as possible.
Avoid handling of static-sensitive modules if not necessary. .
Wear a grounded antistatic wrist strap to drain the static voltage from your
body while touching these modules.
Operate static-sensitive modules only in static-free areas. Avoid handling
modules in areas that allow anything capable of generating or holding a
static charge.
