TB 9-6625-2322-35
IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of Signal Generator, Wiltron, Model 68347M. 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 5
hours, using the dc and low frequency and microwave techniques.
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.
