FPL1000 on its own is a pure spectrum analyzer; the network analyzer can also be used stand-alone; and can be turned into what the company terms a 3-in-1 allrounder by adding the integrated spectrum analysis option and power sensors (R&S ZNL).


The instruments offer flexible solutions for the most important RF measurements. These include the characterization of components such as antennas, attenuators, filters and amplifiers, as well as measurements on signal sources including spectral measurements, analogue and digital signal demodulation and accurate power measurements.


Instruments from the family have a footprint of 408 x 235 mm. This saves up to 60% of space on the workbench compared with conventional solutions. The instruments feature a 10.1-in. WXGA touchscreen, providing a good overview of measurement details. The touchscreen allows users to readily set the centre frequency and reference level and zoom the span or amplitude measurement range. Weighing 6 to 8 kg and featuring a carrying handle and optional battery, the instruments are fully portable and can be used wherever needed.



With frequency ranges from 5 kHz to 3 GHz or 6 GHz, the R&S ZNL offers dynamic range of up to 130 dB (typ.) and an output power range from -40 dBm to +3 dBm (typ.). The measurement speed is high, for instance 16.7 msec (401 points, 100 kHz IF bandwidth, 200 MHz span, two-port calibration). Standard features include embedding/de-embedding, fixture compensation, time domain measurements and support of automatic calibration units.


The instrument can be equipped with full spectrum analyzer hardware. When combined with an R&S NRP power sensor, it turns into a power meter. In this way, the R&S ZNL becomes a true 3 in-1 allrounder that can handle continually changing measurement tasks, helping research and service labs to reduce investment costs.

The R&S FPL1000 spectrum analyzer operates in the frequency range from 5 kHz to 3 GHz. It delivers RF performance with a typical phase noise of -108 dBc at 10 kHz offset (1 GHz carrier) and a displayed average noise level (DANL) of -167 dBm using the optional preamplifier. This performance combined with ease of use suits the R&S FPL1000 for applications in the lab, production and service.


The spectrum analyzer functionality of both the R&S ZNL and the R&S FPL1000 includes a wide range of spectral measurements such as channel power, adjacent-channel leakage ratio (ACLR), signal-to-noise ratio, spurious, harmonic distortions, third-order intercept point (TOI) and AM modulation depth. Versatile marker functions are also provided. With standard 10 MHz or optional 40 MHz analysis bandwidth, the instruments can analyze analogue signals when equipped with the R&S FPL1-K7 option. Digital modulated signals can be characterized using the R&S VSE software and the R&S VSE-K70 option. The R&S FPL1 K30 option, in combination with an external noise source, turns both the R&S FPL1000 and the R&S ZNL into a noise figure meter.
