L4400A Firmware
Procedure to install L4400 Firmware Updates:
- Download and install the Keysight L4400 Firmware Update Utility located in the Documents & Downloads section at the bottom of this page. If you already have the Firmware Update Utility installed on your computer, skip this step.
- Download the latest Keysight L4400 Firmware Revision located in the Documents & Downloads section at the bottom of this page.
- Unzip the Keysight L4400 Firmware Revision file, making note of where you store the unzipped file.
- Open the Firmware Update Utility (Start -> Programs -> Keysight -> Firmware Update Utility).
- Click Next.
- Click Browse and locate the firmware update file (agtL4400Series_instrument_rev251.xs) that you unzipped in step 3. Highlight the file and select Open.
- Click Next.
- Select the I/O interface (LAN or optional GPIB) that connects your L4400 series instrument to your PC.
- Choose the settings necessary for communication (IP address, GPIB address).
- Click Update. NOTE: This update will take several minutes and will automatically reboot the instrument when completed. DO NOT cycle or interrupt power to the instrument during the update process.
- After this is completed, exit the update utility.
Note: For L4445A, remember to connect the 34945EXT to the L4445A before doing the firmware update.
If the ‘ATTN’ annunciator is illuminated following the update/reboot process, cycle power again AFTER the update process completes. If the annunciator remains illuminated, contact Keysight for further assistance.
Repeat this process for each L4400 series instrument
Note: Re-calibration of selected instruments following a firmware update is not required.
