The R&S FSU8 (1166.1660.08) 8 GHz Spectrum Analyzer handles a wide variety of measurement tasks in product development, an instrument must offer ample functionality and excellent performance in all areas of interest. Time-domain power in conjunction with channel or RRC filters turn the FSU3 into a fully-fledged channel power meter. It is just the right instrument for fast data transfer on the IEC/IEEE bus or an Ethernet LAN plus intelligent routines optimized for speed make for very short measurement times. Specifications. Frequency range: 20 Hz to 8 GHz. Reference frequency aging: 1 x 10-7/year; with option ¸FSU-B4: 3 x 10-8/year. Phase noise: typ. -123 dBc (1 Hz) at 10 kHz from carrier. Residual FM: 1 Hz. Sweep time: 2.5 ms to 16000 s (Span >=10 Hz), 1 µs to 16000 s (Span 0 Hz (zero span)). Resolution bandwidth: 10 Hz to 50 MHz, FFT filter; 1 Hz to 30 kHz, channel filter, EMI bandwidth. Video bandwidth: 1 Hz to 10 MHz. Display range: displayed average noise level to +30 dBm. Displayed average noise level (10 Hz RBW): typ. -148 dBm (1 GHz), typ. -144 dBm (7 GHz). Displayed average noise level with preamplifier ON (FSU-B25), 1 GHz, 10 Hz RBW: <-152 dBm. Trace detectors: max peak, min peak, auto peak, sample, RMS, average, quasi-peak.
