Transferring USER Patterns over HP-IB
Pattern Upload/Download Example
Introduction
This section explains some of the subtleties of transferring USER Patterns over GP-IB to
and from the Agilent 70843. A BASIC program example is used to illustrate these and
hints and tips are given for using other programming languages.
The program example is for separate Agilent 70843 Pattern Generators and Error Detec-
tors (Options UHG and UHH) but can be adapted for the Agilent 70843 Error Perfor-
mance Analyzer (Option UHF).
Pattern Upload/Download Example
This program reads the User Pattern Label (line 100) from the Pattern Generator, then the
pattern length (line 110). It then uploads the pattern data into an Array (line 120) after
removing the Header information. The program then re-constructs the Header (line 130)
and sends it to the Error Detector before downloading the pattern data from the array
(line 140).
