Keysight 53210A/53220A/53230A Assembly Level Service Guide

Introduction

This chapter provides service information for your Keysight 53210A, 53220A, and

53230A Counters. It is divided into five major sections:

Returning the counter to Keysight Technologies for service

This section provides you with instructions on how to return the counter to

Keysight for service.

About the Keysight 53210A/53220A/53230A calibration menu

This section contains reference information that gives an overview of the

calibration menu for the Keysight 53210A, 53220A, and 53230A Counters.

The Keysight 53210A/53220A/53230A calibration procedures

This section provides step-by-step procedures for calibrating the

Keysight 53210A, 53220A, and 53230A Counters.

Pre-troubleshooting information

This section provides you with pertinent information such as safety considerations,

recommended test equipment, repair and after-service calibration considerations,

and assembly identification and location.

Troubleshooting information

This section provides you with troubleshooting procedures that can assist you to

isolate an instrument failure to the faulty assembly or module. A final section on

“Error Messages” can be used to help isolate a failed assembly for replacement.

NOTE

Unless otherwise indicated, this manual applies to all serial numbers for the

Keysight 53210A/53220A/53230A Counters.
