Digital controls are provided by the 5520A-4002 for the front panel display and by 5520A-4009 Out-Guard CPU on the rear panel for all external and internal communication.

  • Page 36: Wave Generator Mode

    5820A Service Manual The 5 s to 50 ms markers are generated on A6 and are passed to A55 for filtering and shaping. The 20 ms to 2 s markers are derived from a square wave signal that is generated on A55 and passed through wave shaping and external trigger generation. The 1 s to 20 ns periods are derived from leveled sine or square wave signals.

  • Page 37: Current Module

    Theory of Operation Introduction 2-11. Current Module For the A81 Current Board, A55 supplies the reference signal. This signal is inverted with respect to polarity of the output current (a negative voltage results in a positive current output). A81 has three ranges: 100 µA to 1.0999 mA, 1.1 mA to 10.999 mA and 11 mA to 100 mA.
