This article means to guide maintenance personnel to replace the CPU board of the Saluki S3602 series vector network analyzer.
1. Preventing Electrostatic Discharge Damage
VNA CPU board is a highly integrated PCB board. Protection against electrostatic discharge is essential while handling it. Human body always carries static electricity which can easily damage sensitive internal circuit elements when discharged. Static discharges is too small to be felt but can cause permanent damage. Please check and ensure the following matters before installing/removing a CPU board.
• Always wear a grounded wrist strap, connected to a grounded conductive table mat.
• Always operate on a grounded, conductive table or a table mat.
• Always wear a heel strap when working in an area with a conductive floor.
• Always ground yourself before any operation to the CPU board.
