The A-8000 Spectrum Analyzer is a microprocessor-controlled, superheterodyne unit which features ease of operation, while providing the features of a full-function spectrum analyzer. 1 -2 STANDARD FEATURES The A-8000 Spectrum Analyzer covers a range from 10 kHz to 2600 MHz at signal levels up to +30 dBm. Signal levels are read directly on the CRT graticule display in dBm, dBy W, dBV, dBmV or dBp V. Signals can be stored and recalled or used for comparison purposes. Standard A-8000 input impedance is 50Ω. All operating parameters are set via keyboard operat i on . 1-2-1 DISPLAY METHOD The A-8000 Spectrum Analyzer display is fully digitized. A Vertical Raster Scan (VRSTM-) method is used to form the display of 390 horizontal discrete points by 480 vertical points. The “FULL" Scan display range is from -50 MHz to 2600 MHz. 1-2-2 MEASUREMENTS WITH THE A-8000 SPECTRUM ANALYZER The A-8000 Spectrum Analyzer can be used for a wide variety of measurements within its frequency/am piitude domain. Some of the more important uses include: spectral purity» mixer products, modulation measurements, carrier suppression in Single Side Band radios, harmonic levels, RF carrier levels, distortion and, with the Quasi-Peak filter, electromagnetic interference (EMI) measurements. When equipped with a Tracking Generator, additional measurements can be performed, including: insertion loss, frequency response and return loss (VSWR).
