The manual supplement provides information on new firmware features for spectrum analyzers, including setup and operation enhancements such as trace averaging methods, extended mixer functionality, and new operating modes for GSM and EDGE tests. It also covers troubleshooting aspects like additional IEEE/IEC-bus commands and guidelines for trace export in vector analyzer mode.
Manual Overview
The manual supplement for the Spectrum Analyzer models FSEA20/30, FSEB20/30, FSEM20/21/30/31, and FSEK20/21/30/31 details updates for firmware versions 3.30 and higher, or 4.30 and higher for instruments with Windows NT controllers. Key updates include new trace averaging methods, extended external mixer functionality, and new operating modes for GSM and EDGE tests. The manual provides guidance on selecting trace averaging methods, with options for linear or logarithmic averaging, and includes new IEEE/IEC-bus commands for these functions. The external mixer option FSE-B21 now supports a wider harmonic number range. New firmware applications FSE-K20 and FSE-K21 enable EDGE signal analysis, while extensions FSE-K30 and FSE-K31 introduce measurements in the 850 MHz GSM band. The vector analyzer mode now includes adaptations for EDGE measurements, and the manual explains the process for exporting trace data in ASCII format, suitable for spreadsheet programs. The %THD measurement feature is also detailed, highlighting its use in analog demodulation.
Quick Issues Covered
- Diagnose trace averaging issues with linear/logarithmic settings.
- Resolve external mixer harmonic number setting errors.
- Use schematics for tracing signal paths in vector analyzer mode.

Operation
The manual supplement provides information on new firmware features for the Spectrum Analyzer models FSEA20/30, FSEB20/30, FSEM20/21/30/31, and FSEK20/21/30/31. Key updates include:
1. Selection of Trace Averaging Method: Users can switch between linear and logarithmic averaging for trace display. Logarithmic averaging is recommended for clearer sinewave signal display against noise.
2. External Mixer Option FSE-B21: The harmonic number parameter range has been increased.
3. New Operating Modes: Introduction of EDGE Mobile Tests (FSE-K20) and EDGE Base Station Tests (FSE-K21) for analyzing 8-PSK modulated EDGE signals.
4. Application Firmware Extensions: FSE-K30 and FSE-K31 extend GSM and EDGE test capabilities to the 850 MHz GSM band.
5. Vector Analyzer Mode Enhancements: Includes EDGE measurement with a receiver filter and EVM calculation according to ETSI standards.
6. Analog Demodulation – THD Measurement: Activation of %THD measurement for the main modulation signal.
7. Trace Export for Vector Analyzer Mode: Allows exporting trace data in ASCII format, compatible with spreadsheet programs like MS-Excel.
These updates enhance the functionality and measurement capabilities of the spectrum analyzers.
