Firmware Upgrade Guide E4400-90549
ESG-B Firmware Installation For Versions <B.03.20
Installation Procedure
1.
Navigate to the PSG/ESG Firmware Upgrade Assistant page,
www.keysight.com/find/upgradeassistant
.
2.
Select “OLD Firmware Versions” and then select “E44xxB ESG, OLD Firmware Versions”.
3.
Select the firmware version you wish to use to upgrade your ESG-B.
4.
Repeat the previous step.
5.
Save to any convenient directory. Make note of the filename and directory where you saved
the file; you will need to retrieve it in the next step.
6.
Once the file has been downloaded, locate the file using File Manager/Explorer.
7.
Double click the file. This will trigger the file to extract into a number of smaller files. The
extraction process will automatically place the smaller files in C:\ESG_FW. If you wish to have
the files extracted to a different directory, change the location.
8.
For revision B.02.42 or later, open
DLSERIAL.BAT
. For revisions earlier than B.02.42, choose
dl_com1.bat
if you are using the COM1 port or
dl_com2.bat
if you are using the COM2
port.
9.
Follow the download instructions as they appear on your screen. The download could take up
to one hour to complete. When complete, the DOS window will close. For help following the
download instructions, see
“Helpful Notes for Using this Procedure” on page 17
.
10.
Once the firmware download is successful, disconnect the RS-232 cable.
11.
The files and directories that were created in the earlier steps can now be removed from your
computer.
For firmware revisions B.02.42 and above, the download procedure has changed.
It is no longer necessary to synchronize the powering up of the ESG with the
program. Simply turn the signal generator on and run the program. In addition,
the program will ask you for the COM port, so only one program will need to be
run (
DLSERIAL.BAT
).
If the ESG will not power up correctly (possibly because of a previously failed
attempt at a firmware download) you can still use the older method of firmware
installation with the ESG initially turned off. To do this, open a DOS window,
navigate to the appropriate directory and enter the following command:
DLESERIAL ESG_OFF. This method will download firmware using the powered-off
method.
It is highly recommended that all non-essential computer programs be
terminated before upgrading the firmware. RS-232 overruns could occur if
other programs interrupt the download process.
If your signal generator currently has a firmware revision <B.03.02, and you
want to upgrade to a firmware version >B.03.02, you will need to upgrade
to B.03.02 using the DOS method, then upgrade to the latest firmware
version using the Firmware Upgrade Assistant.
