Cost-effective VNA offers full functionality to 8.5 GHz
The PicoVNA 108 can see out further to 8.5 GHz, and it can see down deeper to –124 dB. The VNA provides new “save on trigger” synchronization for multiple measurements, for example with changing conditions or multiplexed measurement routings. This, added to the convenience of integrated bias-Ts, speeds batch test and device characterizations. Pico Technology has also added offset frequency capability to the Quad RX four-receiver architecture, and synchronization and control of the PicoSource AS108 8 GHz agile synthesizer from within the PicoVNA 3 software. This instrument partnership allows RF mixer and RF/IF system characterizations using the PicoVNA 108. Other popular third-party signal generators are also supported.
Offering a significant price advantage over the traditional VNA, PicoVNAs are based upon anything other than a full-function, professional-grade and widely respected, UK-designed measurement engine. For only £5795 the PicoVNA 108 can deliver all four s-parameters in as little as 190 µs, with high dynamic range and accuracy. (PicoVNA 106 £4205). At these prices the PicoVNAs achieve substantial cost saving for the professional user and are affordable to small and start-up businesses, volume users in the classroom and even some amateur users. Price is comparable with traditionally lower-cost single-port reflectometers and even scalar network analyzers of similar bandwidth.
Users will be aware that calibration standards and interconnects can both dominate measurement errors in network analysis, so Pico supports both PicoVNA models with low-cost but equally impressive SMA and PC3.5 calibration standards and test leads, all with precision-machined stainless steel connectors. PicoVNA software supports 8- or 12-term calibration, including the “unknown thru” method. Unwanted measurement contributions from feedlines or test jigs can be eliminated using manual or auto-sensed reference plane shift, normalization or de-embedded Touchstone, taken from either measurement or EM simulation. Fast Fourier time-domain transformation and impedance transformation are both included as standard. TDT/TDR plots have a system rise time down to 58 ps and these support resistance and distance to fault readout out to over 100 meters.
