Rohde & Schwarz Spectrum Analyzer Preamplifier, 5 kHz to 44 GHz for R&S®FPH var .44 and R&S®FPH var .54 (timed license, 3 months)
The R&S® FPH-K44 preamplifier option (part number 1334.6600.13) is a software license enabling the preamplifier function for the R&S®FPH handheld spectrum analyzer models with frequency ranges up to 44 GHz (var .44) and 54 GHz (var .54). This timed license is valid for 3 months and enhances the analyzer's sensitivity by amplifying weak signals in the frequency range from 5 kHz to 44 GHz. The preamplifier is particularly useful for applications requiring the detection of low-level signals, such as EMI debugging, wireless communications, and spectrum monitoring. The option is activated via a license key and does not require additional hardware installation. It is designed to improve measurement accuracy and dynamic range, making the R&S®FPH more versatile for field and laboratory use.
