International Feeding Bridge

APPLICATION The international feeding bridge SFB 1050 is a very flexible high-quality feeding device for analogue telephone measurements.It can be used as a manually operated single device or remote controlled via IEEE 488 interface in integrated systems. DESCRIPTIONCharacteristics of SFB 1050 ? Voltage source with adjustable current limitation? Current source with adjustable Voltage limitation? Programmable capacitors Cf, Cs and feeding coils ? External feeding mode ? External adaptation of L, Rf and C Measurements The measurement results of the SFB 1050 forReturn loss and Insertion loss are according todifferent regulations (e.g. TBR 38 or EG 201 121/DE-17). KEY FEATURES

? Highly accurate and flexible feeding bridge? Feeding conditions according to all international standards ? Comprehensive user interface with graphical menu and function keys ? Configuration shown on large LC Display ? Memory for user definable feeding configurations ? Operating: Direct and via IEEE 488 ? Programmable dropping resistor, capacitor set and inductor set
