The R&S FSQ26 20 Hz to 26.5 GHz Signal Analyzer offers very low phase noise, unsurpassed low residual EVM, a wide dynamic range and above-average accuracy, making it the ideal high-end measuring instrument for development applications, where tolerances and limit values must often be lower than defined in a standard. Specifications. Frequency range: 20 Hz to 26.5 GHz. RF Performance: DANL with preamplifier < -152 dBm (10Hz); SSB phase noise typ. - 133 dBc (1Hz) at 10 kHz offset, CF 640 MHz; Phase-noise typ. - 160 dBc/Hz @ 10 MHz offset, CF 640 MHz; TOI typ. ±25 dBm; 1-dB-compression point + 13 dBm; 3GPP ACLR 77 dB, 84 dB with noise correction; ACLR for 4-carrier scenario: 77 dB with noise correction. Accuracy: 0.3 dB total level uncertainty up to 3.6 GHz; <0.1 dB linearity error down to -70 dB . IQ Downconverter: IF digitizer 14 bit 81.6 MHz (20.4 MHz IF); IF digitizer 326.4 MHz (option FSQ-B72); IQ Bandwidth (RF) 28 MHz (up to 120 MHz mwith option FSQ-B72); SFDR > 80 dB; IQ memory 16 Msamples each I and Q; output via GPIB or LAN; Sample rate: cont. settable from 10 kHz to 81.6 MHz; e.g. 20 MHz for IEEE802.11a. Speed: 2.5ms sweep time in frequency domain; 1 µs sweep time in time domain; up to 70 remote measurements/s via GPIB; up to 80 manual measurements/s (screen update).
