IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of Sweep/Signal Generator, Wavetek, Model 2001 and SG-677A/U. The
manufacturer's manual and TM11-6625-2955-14 were 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.
