Rohde & Schwarz FSIQ26 Signal Analyzer, 20 Hz to 26.5 GHz

Rohde & Schwarz FSIQ26 Signal Analyzer

These analyzers provide the ideal basis in terms of bandwidth and dynamic range to meet the requirements of W-CDMA standards (ARIB and ETSI). Signal Analyzer FSIQ26 analyzes W-CDMA (wideband code-division multiple access) signals in frequency, time and modulation domains, meeting needs not normally fulfilled by previous instruments at the RF interface.

Essential parameters of the analyzer are resolution bandwidths up to 10 MHz, wide dynamic range, fast sampling in the time domain and capability for processing high chip rates. The superior characteristics of the FSIQ family become evident when looking at the most important measurements, for example at the RF output of a W-CDMA base station.
