IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This procedure provides instructions for the
calibration of Spectrum Analyzer, Agilent, Model 3585B. The manufacturers' 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 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. 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.
