TB 9-6625-2363-35
IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification.
This bulletin provides instructions for the
calibration of Signal Generator, Agilent, Model E4433B. 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. None.
b. Time and Technique. The time
required for this
calibration is
approximately 4
hours, using the dc and low frequency and microwave technique.
2. Forms,
Records, and
Reports. Forms, records, and
reports required for calibration
personnel at all levels are prescribed by TB 750-25.
3. Calibration
Description. TI
parameters and
performance specifications which
pertain to this calibration are listed in table 1.
