    Operation Overview The Calibrator can be operated at the front panel or remotely with the RS-232 or IEEE- 488 ports. For remote operations, software is available to integrate 5502A operation into a wide variety of calibration requirements. Local Operation Typical local operations include front-panel connections to the UUT, and then manual keystroke entries at the front panel to put the Calibrator in the necessary output mode.

  • Page 23: Remote Operation (Ieee-488)

    The SERIAL 2 TO UUT serial data port connects a UUT to a PC or terminal with the 5502A (see Figure 1-2). This “pass-through” configuration removes the requirement for two COM ports at the PC or terminal. A set of four commands control the operation of the SERIAL 2 TO UUT serial port.
