Rohde & Schwarz FSU26 Spectrum Analyzer
The Rohde & Schwarz FSU26 Spectrum Analyzer sets a new benchmark in spectrum analysis, building on the acclaimed RF performance of its predecessors, the R&S FSE and R&S FSIQ series. With its unparalleled dynamic range, the FSU26 simplifies complex measurements in development, quality assurance, and production settings, making it a trusted tool for engineers and technicians.
Key specifications include:
- Third-order intercept (TOI): >20 dBm, typically +25 dBm
- 1 dB compression point: +13 dBm (0 dB RF attenuation)
- Displayed average noise level: –158 dBm (1 Hz bandwidth)
- Adjacent Channel Leakage Ratio (ACLR): 77 dB typical for 3GPP, 84 dB typical with noise correction
- High second-order intercept point (HSOI): 55 dBm typical
- Phase noise: –160 dBc/Hz typical at a 10 MHz carrier offset
These advanced features ensure that even the faintest spurious signals can be detected amidst strong carrier signals, making the FSU26 ideal for applications such as base station testing.
With a superior ACLR of 84 dB for 3GPP adjacent-channel power measurements, the FSU26 allows for fast and precise validation of adjacent-channel power (ACP) ratios—supporting the creation of high-performance node B systems.
The impressive high harmonic second-order intercept point optimizes dynamic range for multichannel cable TV measurements, setting it apart from competitors.
