Handheld Firmware —

PIM Master

Firmware updates replace the code in your Anritsu handheld instruments with the latest, improved code. To see if your instrument needs a firmware update, you will need to check your instrument's firmware version. This can be done by:

  • Turning the instrument on
  • Pressing Shift, System
  • Pressing Status
  • Finding the "Package Version" number. This is the firmware version number.

To update an instrument currently in production:

  1. Locate your instrument type under the tabs above
  2. Download the corresponding firmware update program using your browser
  3. Insert a recently formatted USB memory stick into your computer
  4. Run the downloaded program on your Windows computer

Once the program has run, the firmware update will be on the USB memory stick, ready to be transferred to the instrument. To transfer the update to your Anritsu Handheld Instrument:

  1. Install the USB memory stick in your instrument
  2. Power up your instrument. Please make sure that it is using the AC Power adapter.

At this point, the instrument will detect the firmware update and walk you through the update process. Some of our older instruments have a different firmware update process. Full details are available under the Update Instructions tab above.

Full details, including a video, are available under the Update Methods tab.
