PicoVNA 108 – For Higher Frequencies and Additional Measurement Functions.
For applications up to 8.5 GHz and measurement tasks requiring a higher dynamic range or additional analysis functions. All PicoVNA 106 functions, plus:
- Extended frequency range from 300 kHz to 8.5 GHz
- Dynamic range up to 124 dB
- Mixer measurements
- Phase meter
- Save on Trigger
Reflectometer or Full Two-Port Vector Network Analyzer?
The key difference is not just the frequency range.
The PicoVNA-R is designed for reflection measurements. It measures S11 with full one-port error correction and also S21 via port 2 with source-match correction, normalization and isolation. This makes it suitable for impedance matching measurements, impedance response measurements, fault location and estimating insertion loss.
By contrast, the PicoVNA 106 and 108 measure the complete set of S11, S21, S22 and S12. This is required when devices under test need to be fully characterized in both directions or when two-port de-embedding methods are used.

How can faults in cables and wiring be located precisely? Our Wiki article shows how TDR measurements are performed using a vector network analyzer and an oscilloscope, and explains the differences between the methods.

Common Software: PicoVNA 5.
All three instruments are controlled using PicoVNA 5. The software supports Windows, macOS and Linux and provides, among other features, frequency-domain and time-domain displays, various S-parameter displays, and API and SCPI interfaces for automation.
PicoVNA 5 can also be used in demo mode without a connected instrument. This allows users to familiarize themselves with the user interface and calibration procedures before purchasing an instrument. The software is included with every new PicoVNA, so measurements can begin immediately.
Integrating Picovna into Automated Test Processes.
SCPI commands allow PicoVNA models to be integrated into existing test processes using the command set familiar to test system developers. This is the fastest approach when replacing an existing network analyzer or adopting an established test procedure. A separate API is also available for direct instrument access. It is designed for high data throughput, making it the appropriate choice for continuous measurement and analysis, such as in imaging techniques, radar applications or material property analysis. Programming examples are available for C, C++ and Python, among other languages, including examples for controlling multiple instruments from a single application.
The PicoVNA 5 demo mode enables initial software testing without a connected measurement instrument. Integration code can therefore be written and tested while the hardware is still being procured.
Calibration for Precise Measurement Results.
For reliable measurement results, the PicoVNA models support SOLT calibration. The PicoVNA 106 and 108 also support TRL and TRM methods for devices under test on substrates. Automated E-Cal modules reduce the procedure to a single connection. This saves time, minimizes wear on connectors with a limited number of mating cycles, and eliminates common handling errors from the procedure.
The PicoVNA-R also features an integrated calibrator with short, open and load standards. It does not replace calibration at the measurement plane, but compensates for temperature-related measurement deviations. A previously performed calibration can therefore continue to be used under changing ambient conditions.
