 英國WK6565高頻直流偏壓源

五種機型且最高可升級到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
