Data Logging
Introduction
The Agilent 71612 error performance analyzer can log measurement results via its rear-
panel GP-IB interface to either a printer or an external controller.
The timestamped logging of results and alarms together with a configuration summary
provides a straightforward means of generating a permanent record of, for example, a
conformance test during equipment approval, or performance verification following
installation.
The timestamping of the logged results is crucial for the analysis of time-varying results
after long measurement periods where the instrument is unattended.
Where an electronic copy of the logged results is preferable, then logging to an external
controller allows the logged results to be recorded in an ASCII text file with a minimum of
programming. Refer to the Programming Manual when logging to a controller.
Refer to Measurement Period on page 4-22 for a description of the alternatives for
defining continuous measurement periods know as gating period.
Recommended Printers
The following printers are recommended:
• HP ThinkJet Printer Model 2225A (GP-IB).
• HP QuietJet Printer Model 2227A (GP-IB).
• HP DeskJet series of Printer Control Language (PCL) printers (Centronics).
GP-IB (IEEE-488) to Centronics Printer Interface Converter
A GP-IB (IEEE-488) to Centronics interface converter is required for use with any printer
with a Centronics interface. A suitable adaptor is the Intelligent Interfaces
MicroPrint 45CH orderable under HP part number:
• ITEL-45CHVE for Europe.
• ITEL-45CHVU for North America/Japan/Korea/Taiwan.
To order the correct ac adapter specify:
• F1011A #ABU for UK.
• F1011A #ABB for rest of Europe.
• F1011A #ABG for Australia.
• F1011A #ACQ for South Africa.
The adaptor switches 1234 should be set to 1000 as the Agilent 70843 expects to log to an
GP-IB printer at address 1.
