    Definitions This section contains definitions, descriptions, and other pertinent information needed to operate the ARB portion of the 3314A. Topics are listed in alphabetical order. Amplitude sets the peak-to-peak voltage that the ARB wave must exist within (not affected by DC Offset). The peak to peak amplitude also affects the resolution of V HGT (see Vector Height).

    THE STATUS BYTE The Status Byte is an 8 bit word that the 3314A will output when involved in a Serial Poll. The state of each bit or 0) indicates the status of an internal 3314A function. A bit will be set after that bit has been unmasked and the bit condition bitlsl is satisfied.

    By modifying the following programs, you can: - read vector values from the 3314A to arrays, then store them to a host computer's mass storage device. - enter vector parameters directly to an array, then write them to a 3314A ARB register.
  • Page 107 Reading and Writing Vector Parameters following example contains two parts. The first part reads vector values from ARB register 0 into an array. The second part writes the array contents to ARB register 1, building the waveform. To use this program as an exercise, build Waveform 51 in the WAVEFORM LIBRARY section of this manual.
