T02 and T04 files

In general, to maximize the amount of data that can be stored, use the T02 format. However, if you want to use a more feature-rich format that will help Trimble with any support issues, use the T04 format.

T04 file features

  • One-minute spectrum analyzed logs.

  • FLL frequency-locked loop data.

  • Error/warning logs are embedded in T04 files.

  • The doppler from each signal is stored independently, no synthesis is required.

  • For receivers that include IMU hardware and have the INS option enabled, but INS Mode disabled, the raw sensor data from the IMU is logged.

The T04 file format is the default data logging file format.

T02 file features

  • Logs PLL phase-locked loop data.
