Rohde & Schwarz Spectrum Analyzer Preamplifier, 5 kHz to 44 GHz for R&S®FPH var .44 and R&S®FPH var .54 (timed license, 1 month)
The R&S®FPH-K44 preamplifier option (part number 1334.6600.11) is a software license enabling the preamplifier function for the R&S®FPH handheld spectrum analyzer, specifically for variants .44 and .54. This option extends the analyzer's sensitivity by activating a low-noise preamplifier covering the frequency range from 5 kHz to 44 GHz. The preamplifier improves the instrument's noise floor, allowing for the detection of weaker signals and more accurate measurements in challenging RF environments. This is a timed license valid for one month, ideal for temporary projects or evaluation purposes. The option is activated via a license key and does not require additional hardware installation.
