1 Performance Tests Verifying Specifications
Chapter 1 Performance Tests Introduction Introduction This chapter provides procedures to test the electrical performance of the Agilent 53210A/53220A/53230A Frequency Counters, using the specifications provided on the CD-ROM (“Agilent 53210A/53220A/53230A Specifications”) that came with your counter. Successful completion of all the Performance Tests verifies the counter is meeting all factory specifications.
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. Successful completion of the Self-Test provides a high confidence level that the counter is completely functional. No external test equipment is required for this operator-inititated test.
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: • Perform the counter Self-Test as shown on page 19. • Perform only the performance verification tests indicated with the letter Q at the beginning of the test.
Chapter 1 Performance Tests Introduction • To verify the total number of accuracy places for frequency measurements, it may be necessary to turn off Auto-Digit control. Use this set of key depressions to turn AutoDigits OFF: [Digits] / (AutoDigits) / • The softkey menus shown in the test procedures represent the functionality of the 53230A. The softkey menus for the 53210A and 53220A may be different depending on the function selected.
