SECTION I. GENERAL INFORMATION
Option HI8 to the HP Model 8662A Synthesized Signal Generator provides an 8662A selected
for single-sideband phase noise better than the standard specifications. Option H03 (which provides a
rear-panel 640 MHz low-noise output) must be ordered with Option HI8. All single-sideband phase
noise measurements are defined and guaranteed as measured on an HP 3047A Spectrum Analyzer
System with suitable low-noise local oscillators. Because of the nature of these noise measurements,
no allowance has been included in the Option HI
8
specifications for the uncertainty of the 3047A
measurements or any uncertainty caused by temperature or other environmental variations.
