The manual supplement provides updates on the setup, operation, and troubleshooting of the Spectrum Analyzer models FSEA20/30, FSEB20/30, FSEM20/21/30/31, and FSEK20/21/30/31 with firmware versions 3.30 and higher, including new functionalities such as trace averaging methods, extended external mixer capabilities, and new operating modes for GSM and EDGE signal analysis. It also details additional IEEE/IEC-bus commands, trace export options, and specific instructions for using the vector signal analysis mode and analog demodulation.
Manual Overview
The manual supplement for the Spectrum Analyzer models FSEA20/30, FSEB20/30, FSEM20/21/30/31, and FSEK20/21/30/31, details firmware updates from version 3.30 and higher for instruments without a controller function or with DOS, and from version 4.30 and higher for those with Windows NT. Key updates include the selection of trace averaging methods, with options for linear and logarithmic averaging, particularly beneficial for noise suppression in sinewave signals. The external mixer option FSE-B21 now supports a wider harmonic number range. New application firmware, FSE-K20 and FSE-K21, enhances EDGE signal analysis capabilities for GSM and EDGE tests, while FSE-K30 and FSE-K31 extend these functions to the 850 MHz GSM band. The vector analyzer mode, with option FSE-B7, now includes EDGE measurement adaptations. Additionally, the manual introduces ASCII export functionality for trace data in vector analyzer mode, allowing for easy integration with spreadsheet programs. The %THD measurement feature is also detailed, providing a percentage display of total harmonic distortion for modulation signals.
Quick Issues Covered
- Diagnose trace averaging issues with MODE AVERAGE LIN/LOG selection.
- Resolve external mixer errors by adjusting HARMONIC NUMBER settings.
- Use schematics for circuit tracing when dealing with vector analyzer mode.
