Rohde and Schwarz FPL1-K30 - Noise Figure and Gain Measurements Option

This requires the FPL1-B5 additional interfaces option, as well as a noise source, such as the R&S FS-SNS26 smart noise source.

The R&S FPL1-K30 noise figure and gain measurement option allows you to characterize the most important amplifiers specifications. Using the Y-factor method, the noise figure and gain are measured with high accuracy independent of the instruments own noise figure.

Typical applications for the R&S FPL1-K30 include the characterization of amplifiers.

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

• Noise figure in dB
• Gain in dB
• Y factor in dB

The noise source is controlled by the 28 V output on the R&S FPL1-B5 additional interfaces option on the back of the instrument. With an optional R&S FPL1-B22 RF preamplifier, the sensitivity of the measurement can be improved for measuring devices with a low noise figure, e.g. LNAs.

The advantage of the R&S FPL1-K30 compared to conventional noise measurement systems is that a wide variety of other RF measurements can also be performed with one instrument, for example measurement of harmonics, intermodulation, spurious responses.

When used with the ZNL vector network analyzer, option ZNL3-B1, ZNL4-B1 or ZNL6-B1 is also required.
