IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Oscilloscope, OS-288/G (Tektronix, Type 2465B) and Tektronix, Types 2465B
OPT46 and 2467B. 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. Tektronix, Type 2465B OPT46 and 2467B OPT10 are equipped
with an IEEE bus.
b. Time and Technique. The time required for this calibration is approximately 6
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 adjustments.
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.
