Rohde & Schwarz Enhanced dynamic range preamplifier. Only available for instruments with FSW- B24. Retrofittable in Rohde & Schwarz service (upgrade)
The Rohde & Schwarz FSW-B24 Enhanced Dynamic Range Preamplifier is an optional hardware upgrade designed exclusively for the FSW signal and spectrum analyzer series. This preamplifier significantly improves the analyzer's dynamic range, enabling more accurate measurements of low-level signals in the presence of strong interferers. The FSW-B24 is only available for instruments already equipped with the FSW-B24 option and must be retrofitted by Rohde & Schwarz service personnel. It is not a user-installable accessory. The upgrade enhances measurement sensitivity and is ideal for demanding applications such as phase noise, spurious, and adjacent channel power measurements. The preamplifier is fully integrated into the instrument's signal path and is controlled via the analyzer's user interface, ensuring seamless operation and optimal performance.
