Rohde & Schwarz FSU26
Spectrum Analyzer 20Hz to 26.5GHz
Description
This Spectrum Analyzer is based on the proven 3GHz and 8GHz models of the FSU family and offers the same high grade characteristics as well as identical operation and measurement functions.
Fundamental mixing in the entire frequency range up to 26GHz ensures very high sensitivity to the highest input frequency.
The R&S FSU26 thus meets a major prerequisite for wide dynamic range and allows measurement of very small signals (e.g. harmonics and non harmonics) with sufficient S/N ratio and consequently low measurement uncertainty.
Measurement uncertainty in the upper microwave range is to a large extent
determined by the frequency response of the YIG filter.
<
p>In this case, the patented frequency response correction ensures a figure of <2dB to 22GHz and <2.5dB to 26GHz without the peaking usually required.
