# FSL-K30 Rohde & Schwarz NEW

**Features:**

-   Noise figure and gain measurements option
-   Requires option FSL-B5, preamplifier and noise source
-   Provides features otherwise only provided by special noise measurement analyzers
-   The following can be measured at a specified frequency or in a selectable frequency range: Noise figure in dB, Noise temperature in K, Gain in dB
-   Application Firmware for Noise Figure and Gain Measurements

The R&S FSL-K30 application firmware provides the R&S FSL spectrum analyzer with features otherwise only provided by special noise measurement analyzers.

The following parameters can be measured at a specified frequency or in a selectable frequency range:

-   Noise figure in dB
-   Noise temperature in K
-   Gain in dB

Compared with conventional noise measurement systems, R&S FSL-K30 has the advantage that a wide variety of further RF measurements can also be performed. The R&S FSL also allows the measurement of harmonics, intermodulation, spurious responses and many other RF relevant criteria (for measurements on amplifiers and on frequency-converting DUTs, e.g. low-noise converters).

##### Noise measurements

-   Measurement range 0 dB to 35 dB
-   Resolution 0.01 dB
-   Measurement accuracy ±0.3 dB (measurement with external preamplifier (gain 30 dB, noise figure < 5 dB) and 1 MHz resolution bandwidth, valid for DUTs with noise figure 1 dB to 10 dB and gain > 10 dB)

##### Gain measurements

-   Measurement range 0 dB to 60 dB
-   Resolution 0.01 dB
-   Measurement accuracy ±0.2 dB (measurement with preamplifier (gain 30 dB, noise figure < 5 dB) and 1 MHz resolution bandwidth)

##### Required hardware

-   R&S FSL-B5 noise source power supply (via 28 V connector on the R&S FSL rear panel)
-   Noise source, e.g. NoiseCom NC346
-   External preamplifier (for improved accuracy and repeatability of measurements)
