International Feeding Bridge ISB 1000:
Although standardization within telecommunications becomes more and more important, analogue telephone networks are still different from country to country. Very important for testing TE according to various national requirements is the simulation of many different feeding conditions.

The international feeding bridge ISB 1000 can simulate almost any feeding condition. ISB 1000 is an extremely flexible high-quality instrument that can be used either as a stand-alone laboratory instrument or as an IEEE controlled and integrated part of a system.

A large frontpanel display gives all necessary information about setups, signal flow, and adjustable parameters. A softkey controlled menu enables the user to configure ISB 1000 according to his individual needs.

Features:

• Extremely versatile feeding bridge meeting nearly all international standards
  
• Comprehensive user interface with graphical menu and softkeys
  
• Loop current value displayed numerically and graphically in a bar chart
  
• Memory for country-specific and user definable setups and configurations
  
• External feeding mode
  
• U-mode/voltage source: 1-204.75 V / 1-204.75 mA
  
• Current source (I-mode): 1-204.75 mA / 1-204.75 V
  
• Dropping resistance 5-12.795 ohms, symmetrical, 5 ohms step size
  
• Switchable capacitors: 1-100 µF
  
• Switchable inductivities 1-16H, DC-resistance 8.5 ohms per H
  
• Additional line resistance for inductivities: 0.5-797.5 ohms and optional
  
• Switchable outputs, reversed polarity
  
• 19" 4HE EMC-proofed cabinet with large LC display (80x100mm)
