Description

4-port Vector Network Analyser covering frequencies from 10 MHz to 67 GHz. In addition to S-parameters, this asset should allow for noise figure measurements, up to 50 GHz, of low gain and low noise devices.

Total Quantity or Scope

The unit must have all performance characteristics as detailed below: 4-port Vector Network Analyser with the following specifications: • Lower frequency limit 10 MHz (maximum) • Upper frequency limit 67 GHz (minimum) • 4 ports • 1.85 mm coaxial test port interface • Hardware realised noise measurements up to 50 GHz • GPIB interface • CE or UKCA marked with declaration of conformity • 220 V operating mains voltage Performance specifications Typical corrected system performance at 60 GHz as follows: • Noise floor for 10 Hz IF Bandwidth across frequency range 100MHz to 67GHz: ≤-100 dBm, Direct Rx Access ≤-100 dBm across the whole band. • System dynamic range ≥107 dB from 50MHz to 67GHz. Corrected Numbers, after a calibration. • Directivity at 50-67GHz: ≥ 34 dB • Source match at 50-67GHz: ≥ 40 dB • Load match at 50-67GHz: ≥ 33 dB • Reflection tracking (Mag) at 50-67GHz: ≤ ±0.031 dB • Transmission tracking (Mag) at 60-67GHz: ≤ ±0.15 dB • Three harmonically clean DDS RF sources, with harmonics better than -60dBc • Internal signal combiner, a flexible set of switches and direct generator and receiver access points which can all be reconfigured for non-standard measurement applications without the need for an external test set or switching. • Linearity at test port < 0.05 dB @ -60 dBm across frequency band. • Dual DDS sources providing 94dBc/Hz phase noise performance at 10kHz offset at 10GHz carrier (typical) Additional Features • Noise Figure using built-in low noise receiver and filtering allowing for low gain, low noise measurements of amplifiers and converters • Source corrected Vector noise figure measurements suitable for measuring low gain, low noise devices.

Legal Justification

The specification for the instrument that is needed to deliver the cutting-edge science is supplied by a specialist of scientific equipment, the specific needs are around low noise measurement which Keysight offer as a special built option rather than a software adjustment. Integration with NPL software written around interaction with Keysight equipment (Time already spent with science teams – a effective plug and play requirement) is highly desirable. Specifically compatible with NPL PIMMS software (designed around Keysight PNA remote interface command set) as this software is complex and would require significant of time to rewrite the software. In addition, Keysight offer a trade in service on all new purchases with items currently at NPL which are no longer useable or required by the science teams, this will be a significant saving. We currently have at least two items that fit the criteria for a trade in with Keysight, one is a unfeasible repair and one is an old 8510 unit that was one of the first to enter the UK which has since been super seeded by more modern equivalents which offer greater measurements options.
