Using FieldFox Analyzers with Mass Storage Devices

Application Notes

This document describes the capabilities of using FieldFox with mass storage devices. FieldFox analyzers come equipped with sufficient internal memory for most applications, but it is convenient to be able to use external storage devices such as USB flash drives for record keeping, transferring files, or copying limit lines, masks or cable correction files between multiple analyzers. Industries such as the aerospace and defense sector will often limit the use of standard USB flash drives for security reasons. This document describes in detail the types of mass storage devices that could be used with FieldFox analyzers.

Terminology

The terms USB storage device, USB device, USB stick, thumb drive, and flash drive are used interchangeably.

– FAT32: File Allocation Table, 32-bit

– ExFAT: File Allocation Table Extension

– NTFS: New Technology File System

This document references Keysight FieldFox analyzers with the original CPU versus Keysight FieldFox analyzers with the newer, faster CPU or CPU2. FieldFox analyzers shipped after August 2016 included a newer, faster CPU, however older units could have been upgraded. To verify the CPU version of the FieldFox analyzer, check the firmware using the steps listed below.

  • [System] {Service Diagnostics} {System Information} {BIOS Rev}
  • Analyzers with the original CPU will state 2.4.0.
  • Analyzers with the newer, faster CPU will state CPU2.
