TB 9-6625-2334-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Universal Counter, Hewlett-Packard, Model 5328B( ). The manufacturer's
manual was used as the prime data sources in compiling these instructions. The
equipment being calibrated will be referred to as the TI (test instrument) throughout this
bulletin.
a. Model Variations: Model 5328B may have the following options:
010
High-stability time base oscillator.
021
Digital voltmeter.
031
Channel C (90-1300 MHz frequency range).
b. Time and Technique. The time required for this calibration is approximately 2
hours, using the dc and low frequency technique.
2. Forms, Records, and Reports
a. Forms, records, and reports required for calibration personnel at all levels are
prescribed by TB 750-25.
b. Adjustments to be reported are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables, the (R) follows the designated adjustment.
Report only those adjustments made and designated with (R).
3. Calibration Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.
