One point to remember about network ("Notwork") analysers is that they, like vector voltmeter and directional coupler measurements, rely on the accuracy of the couplers. If you are measuring an impedance with a high SWR (e.g. say 1,000 Ohms) then something like a 0.1 dB inaccuracy can lead to a +/-50% error. For high SWR type measurements, a resonance type measurement is preferable. 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
