  • Page 5: Introduction

    Introduction This document defines the remote interface commands for the 5560A/5550A/5540A Calibrator (the Product or Instrument). A computer can connect through any of the remote interface ports to change settings, read measurement data, and control the operation of the Product. Command syntax and names follow the IEEE-488.2 standards.

  • Page 6: Remote Operations

    Write programs carefully and test them extensively to ensure safe operation of the Calibrator. Fluke Calibration recommends that you include routines to catch errors in your programs. These routines help to identify programming errors that can cause the Calibrator to behave other than intended.
