WHAT IT DOES

The CIA-HF Complex Impedance Analyzer combines a microprocessor-controlled direct digital
synthesizer with an accurate low-power Impedance bridge to present a graphical display of SWR,
Impedance, Resistance, or Reactance. To create these graphical displays, the Analyzer
continuously sweeps and plots a user-selectable frequency range. Alphanumeric data blocks
common to each graphing screen are updated after every frequency sweep
The Analyzer provides two modes of operation - a simple mode and an expert mode. When first
activated, the Analyzer defaults to the simple mode, which operates with two graphing screens
and enough data for basic antenna assessment only. The expert mode provides the experienced
user with four additional screens and more detailed data.

FEATURES

Graphical display of SWR, total Impedance, Resistance, and Reactance vs. frequency
u
Graphical vector display of Real, Imaginary, and total Impedance with Phase Angle
