How to Install

 - To update your oscilloscope's firmware, do one of the following:
Place the file on a USB flash drive, connect it to the oscilloscope, press [Utility] > File Explorer, select the file; then, press Load File.
If your oscilloscope is on the network: you can place the file on your computer, access the oscilloscope's Web Interface (see the User's Guide for details), click Instrument Utilities, select Firmware Version, browse to select the file; then, click Install.
 - After your oscilloscope's firmware is updated, check the calibration status: press [Utility] > Service > User Cal Status. If "Results: OK" is displayed, you do not need to recalibrate. If calibration is required, press the Start User Cal softkey. 

NOTE:

When upgrading your oscilloscope, download the .agx file, and load the complete file into the oscilloscope. Do not “unzip” the file.

About Device Firmware:

Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.

On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.

When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.

As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.

Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
