TB 9-6625-1966-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Function Generator, Hewlett-Packard, Model 3300A with Aux Unit Plug-in,
Model 3301A; Trigger/Phase Plug-in, Model 3302A; Sweep/Offset Plug-in, Model 3304A;
and Sweep Plug-in, Model 3305A. The manufacturers' manuals were 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. Section III applies to TI's with SN prefix 630. Designators
enclosed in parenthesis pertain to SN prefix 519, 533, 609, 616, 622, and above.
b. Time and Technique. The time required for this calibration is approximately 3
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.
