R&S®FSH18 Handheld Spectrum Analyzer

10 MHz to 18 GHz

Applications

Power measurements

When the accessory Power Sensor R&S®FSH-Z1 or R&S®FSH-Z18 is fitted, the R&S®FSH3 is transformed into a high-precision RF power meter with a maximum frequency of 8 GHz or 18 GHz. As with thermal sensors, the true RMS value of the measured signal is obtained over the whole measurement range irrespective of the signal waveform. This is particularly relevant when measurements are made on modulated signals because no additional measurement errors are introduced. The measurements are straightforward, which is very important for digitally modulated signals such as 3GPP. The large measurement range which covers 200 pW to 200 mW (equivalent to a dynamic range of 90 dB) turns the R&S®FSH3 with the R&S®FSH-Z1 or R&S®FSH-Z18 into a universal RF power meter.
