Firmware Prerequisites
Agilent 81560A, 81561A, 81566A, & 81567A Optical Attenuator Modules, First Edition 5
Firmware Prerequisites
For Agilent 8156x modules with a particular firmware revision to
operate correctly, your Agilent 8163A/B, 8164A/B, or 8166A/B
mainframe must have a V3.5, or later, firmware revision installed.
Firmware files are provided on the OCT Support CD-ROM supplied
with the instrument, and the latest firmware revisions can also be
downloaded via www.Agilent.com/comms/comp-test
The firmware for A and B versions of our mainframes is not binary
compatible. Make sure you select the appropriate firmware for your
instrument.
NOTE • Updating mainframe firmware does not require you to update the
firmware in every hosted module. New revisions of mainframe
firmware are backwards compatible with older module firmware.
• You may find it advantageous to update module firmware. To help
you determine which module firmware to update, a readme file is
provided with the firmware file detailing its revision history.
• If the serial number of your HP 8164A Lightwave Measurement
System is DExxxxx339 or below, problems with writing files to the
floppy disk drive may occur in rare cases. If this is the case, please
contact your nearest Agilent Technologies Sales / Service Office.
