Agilent 8166A Firmware Upgrade Procedure
To upgrade firmware for the Agilent 8166A, you require a PC, running MS
Windows 95 or NT 4.0, or higher, plus a serial null-modem cable, that was
supplied with your Agilent 8166A mainframe.
Perform the following instructions (“xxx” in a filename should be replaced
by the current release number, i.e. 402 for release 4.02):
1 Copy the directory Firmware\8166A from the Support Disk to a directory on
your PC. This directory contains the files "HPFlashWinR5.exe" and
"66_flxxx.bin".
2 Click on HPFlashWinR5.exe to start the HPFLASH software.
3 Press the "File Selection" button, the file selection box appears.
4 Move to the file "66_flxxx.bin" and click on OK.
5 Click on 'Port Settings'.
6 Select the com port where the serial cable is connected. Choose the maximum
baud rate. Click on OK.
7 Turn on the 8166A and wait for the first beep.
Now you must be quick:
• Press and hold the Preset hardkey.
• Still holding Preset, press and hold the Aux hardkey.
• Still holding Preset and Aux, press and hold the Appl hardkey.
Tip: Use three fingers and place them near the keys in advance!
If you were successful, you hear a double beep and the display shows that the
instrument is in download mode. Otherwise, turn off the power and try again.
8 Click on 'Program' and wait until the download completes. The instrument will
reboot with the new firmware.
