HP 8657A High Frequency Generator

The Hewlett Packard HP 8657A High Frequency Generator 100 kHz to 1040 MHz Spectral Performance for general-purpose Test, designed to test AM, FM and pulsed receivers as well as electronic components. Analog modulation, spectral purity and a good output level performance ideal for manufactoring or Research & Development. Also good for testing amplifier, inductors, capacitors, operational amplifiers - where ever you need a higher frequency, a fine instrument.

Ein Hochfrequenzgenerator geeignet für allgemeine Anwendungen z.B. zum Test von AM und FM Empfängern und natürlich Bauelemente. Ein Gerät geeignet zur Unterstützung von Elektronikentwicklern. Selbst für Audio Entwicklung immer noch zu gebrauchen - Test von Bauteilen, Transistoren, Induktivitäten, Kondensatoren, Operationsverstärker - wo immer eine hohe Frequenz benötigt wird, der 8657A stellt eine zur Verfügung.
