R&S®FS-K30 Application Firmware for Noise Figure and Gain Measurements for R&S®FSP, R&S®FSU and R&S®FSQ (preamplifier recommended, e.g. R&S®FSU-B23, R&S®FSU-B24, R&S®FSU-B25)

The combination of Application Firmware R&S^®FS-K30 and Analyzers R&S^®FSP/FSU or R&S^®FSQ offers the following advantages over conventional noise measurement systems:

• Frequency range up to 67 GHz (depending on analyzer model) for noise measurements in the micro wave range without requiring an additional downconverter
• Resolution bandwidths variable in steps of 1/2/3/5 (R&S^®FSP: only 1/3) for optimum matching to narrowband DUTs

While conventional noise measurement systems are only suitable for determining the noise and gain characteristics of the DUT, the R&S^®FSP/FSU or R&S^®FSQ also allow the highly sensitive measurement of the following parameters:

• Harmonics
• Intermodulation
• Spurious responses

and many other RF-relevant criteria (for highly sensitive measurements on amplifiers and measurements on frequency converting DUTs, e.g. low noise converters).

• Level range 0 dB to 25 dB
• Resolution 0.01 dB
• Measurement accuracy ±0.2 dB (measurement with preamplifier (gain 20 dB, noise figure 5 dB) and 1 MHz bandwidth, valid for DUTs with noise figure 1 dB to 10 dB and gain >10 dB)

• Level range 0 dB to 60 dB
• Resolution 0.01 dB
• Measurement accuracy ± 0.2 dB (preamplification 20 dB, noise figure 5 dB, bandwidth 1 MHz)

For improved accuracy and repeatability of measurements a preamplifier (Option FSx-B25) is strongly recommended.
