Introduction

This document describes version 1.2.5 of the firmware for the ThinkRF R57x0 family of real-time spectrum analyzers. It is distributed as a single binary file, ThinkRF_R57x0_firmware_v1-2-5.img.


This version of the R57x0 firmware is compatible with all ThinkRF R5700 (all models) and R5750 (all models).

Important Note: If your R57x0 has firmware v1.720/1.2.1, it is strongly recommended that the RTSA should be updated to this new version or higher.


Fixed Defects

The following issue(s) are fixed in this version:

  • Fixed an issue affecting sweeping with the -418 and -427 product variants. (-408 product variants are unaffected)
    • Sweeping from DD mode into SH mode with the preamp enabled would not correctly enable the preamp in the first step in SH mode. In the case of a full-span sweep configuration, this would cause gain to be reduced by ~20 dB for a 40 Mhz span between 50 MHz – 90 MHz.


Known Issues and Limitations

The following are the known limitations or other issues present:

  • Very occasionally, the :SYSTem:DATE or :SYSTem:TIME command will return an error. When that happens, issue the command again.
