Analysers set for European Microwave Week premiere

2nd October 2017

The R&S ZNL network analyser and the R&S FPL1000 spectrum analyser will be launched by Rohde & Schwarz at European Microwave Week 2017 in Nuremberg (10-12 October). They offer flexible solutions for the most important RF measurements. These include the characterisation 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 new family have a footprint of just 408 mm x 235 mm. This saves up to 60% of space on the workbench compared with conventional solutions. The instruments feature a large 10.1in 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 just 6 kg 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 5kHz to 3GHz or 6GHz, the R&S ZNL is well suited for various RF component measurement applications in industrial electronics and wireless communications. The instrument offers solid network analyser performance with a dynamic range of up to 130dB (typ.) and an output power range from -40dBm to +3dBm (typ.).

The measurement speed is very high, for instance 16.7ms (401 points, 100kHz IF bandwidth, 200MHz span, two-port calibration).

Standard features include embedding/de-embedding, fixture compensation, time domain measurements and support of automatic calibration units.

The R&S ZNL can be equipped with full spectrum analyser hardware. When combined with an R&S NRP power sensor, it turns into a power meter.

In this way, it becomes a true 3 in-1 all-rounder that can handle continually changing measurement tasks, helping research and service labs to reduce investment costs.

The R&S FPL1000 spectrum analyser operates in the frequency range from 5kHz to 3GHz. It delivers solid RF performance with a typical phase noise of -108dBc at 10kHz offset (1GHz carrier) and a displayed average noise level (DANL) of -167dBm using the optional preamplifier.

This performance combined with ease of use makes the instrument ideal for applications in the lab, production and service.

The spectrum analyser 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 analyse analogue signals when equipped with the R&S FPL1-K7 option.

Digital modulated signals can be characterised 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.
