IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of Modulation Analyzer, Hewlett-Packard, Model 8901A w/Options 002 and 010.
The manufacturer's manual was used as the prime data source in compiling these
instructions. The equipment being calibrated will be referred to as the TI (test instrument)
throughout this bulletin.
a. Model Variations. Variations among models are described in text, tables, and
figures.
b. Time and Technique. The time required for this calibration is approximately 4
hours, using the dc and low frequency technique.
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).
pertain to this calibration are listed in table 1.
