Keysight Module Firmware Upgrade Procedure
Keysight module firmware is upgraded via GPIB (recommended) or a serial
null-modem cable.
You require a PC running Windows. To update via GPIB the PC must be
fitted with a suitable GPIB adapter. Alternatively, a serial null-modem
cable is required, such as is supplied with your mainframe.
You also require the module update program, which is supplied both on
the Support CD-ROM and as a web download. Copy Module_Update.exe
to a directory on your PC’s hard drive, then execute Module_Update.exe to
install the module update program.
