Upgrade Instructions for the Spectrum Analyzer Driver

Before using the spectrum analyzer unit, its drivers have to be installed. If upgrading from version 14.3.x or earlier, you must update the RSA driver before using Tagformance with the Spectrum Analyzer. Starting from Tagformance 14.4, the software requires the 64-bit RSA driver.

Please follow the steps below to ensure proper setup of the updated 64-bit RSA driver:

Step 1 – Install the 64-bit driver

  1. Locate the installer in the software package:
    RSA_API_USBDriver_x64/setup.exe
  2. Run the installer and complete the setup.
  • The package includes both 32-bit and 64-bit APIs, but only the 64-bit API is supported from version 14.4 onward.
  1. Restart your PC if prompted.

Step 2 – Update the configuration

  1. Open the configuration file:
    configuration.cfg
  • File location: Tagformance\Data\configuration.cfg
  1. Find the entry:
    [Spectrum Analyzer Configuration]
  • If the entry does not exist, create it (add a blank line before the section header).
  1. Add or update the following line exactly:

RSA API file path = “/C/Tektronix/RSA_API/lib/x64/RSA_API.dll”

  • If your configuration file currently points to:

RSA API file path = “/C/Tektronix/RSA_API/lib/x86/RSA_API.dll”

Replace it with the new 64-bit path above.

✅ What the configuration file section should look like:

[Spectrum Analyzer Configuration]

RSA API file path = “/C/Tektronix/RSA_API/lib/x64/RSA_API.dll”
