英国WK6565高频直流偏压源

五種機型且可升級到120MHz

6565B A5A /A 10A : 20Hz to 10MHz

6565B B5A /B 10A : 20Hz to 20MHz

6565B C5A /C 10A : 20Hz to 30MHz

6565B D5A /D 10A : 20Hz to 50MHz

6565B E 5A /E 10A : 20Hz to 120MHz

Component tests up to 40A DC bias current

Component inductor tests up to 40A

High accuracy for DC bias current ±1%

Applications: Permits measurement analysis of wound components with levels of DC bias current higher than the standard 200mA for high frequency signals in coils

Control connections: Serial Communication Bus controls application of DC current and monitors status of analyzer. Status data includes excessive voltage drop and over temperature

Optional facilities: 6565B bias units may be paralleled, maximum of four same model units

Interlock: Bias safety interlock socket on rear panel of analyzer provides door lock and closed control lines
