Page 14: Introduction
Chapter 1 Performance Tests Introduction Introduction This chapter provides procedures to test the electrical performance of the Keysight 53210A/53220A/53230A Frequency Counters, using the specifications provided on the CD-ROM (“Keysight 53210A/53220A/53230A Specifications”) that came with your counter. Successful completion of all the Performance Tests verifies the counter is meeting all factory specifications.
Page 15: Chapter Overview
Chapter 1 Performance Tests Introduction Chapter Overview Power-On Test When the counter is first turned ON, a limited turn-on test is performed to verify the counter is sufficiently functional to perform basic operations. Self-Test Running the counter Self-Test initiates a series of checks against internal standards.
Page 16: Performance Test Record
Chapter 1 Performance Tests Introduction Auditing the counter’s performance for the quick check points (designated by a ‘Q’) verifies performance for normal accuracy drift mechanisms. This test does not check for abnormal component failures. To perform the quick performance check, do the following: •...

Page 19: Power-On Test
Chapter 1 Performance Tests Power-On Test Power-On Test Inspect the counter for any damage. Make sure no cables are connected to the input channels (rear and front panels) of the counter. Connect the power cord to the counter, and connect the other end of the power cord to the primary power source.
Page 20 Chapter 1 Performance Tests Power-On Test An Auto-cal is performed at power-on. (See “To Run NOTE AutoCalibration:” on page 143 for more information.) If a fail message is displayed at power-on, refer to NOTE “Troubleshooting the Counter” on page 156 of this service guide. Mark Pass or Fail in the Keysight 53210A/53220A/53230A Power-ON Test Record, Test 1, at the end of this chapter.
Page 21: Self-Test (Q)
Chapter 1 Performance Tests Self-Test (Q) Self-Test (Q) A brief power-on test occurs automatically whenever you turn on the counter. This limited test assures that the counter is functional. It is recommended that the counter Self-Test be performed to NOTE ensure that the instrument is completely functional before running the Operational Verification or Performance Tests.

Chapter 1 Performance Tests Keysight 53210A/53220A/53230A Operational Verification Keysight 53210A/53220A/53230A Operational Verification The operational verification consists of checks that may be performed at any time to give a high degree of confidence that the instrument is operating properly, without running the complete performance tests. These checks represent the minimum set of tests recommended following any option retrofit installations (Refer to Chapter 4).
Page 24 Chapter 1 Performance Tests Keysight 53210A/53220A/53230A Operational Verification If the counter has Option 201 (rear panel input connectors) NOTE installed, connect the Int Ref Out to the rear panel Channel 1 input connector and NOT the front panel Channel 1 input connector. Press the Preset key to preset the counter.
