![]() ![]() The two ports become auto-lock receivers at any user-specified frequency within the 300 kHz to 8.5 GHz tuning range of the VNA. The phase meter adds a valuable phase and amplitude alignment and stability measurement capability to the PicoVNA 108. If, however, a change of sweep settings is necessary for a measurement, the PicoVNA software will for convenience interpolate its corrections to the new sweep settings.Īn enhanced isolation calibration setting is available for optimum dynamic range when using resolution bandwidths below around 1 kHz. When using an automated E-Cal SOLT standard, an extended set of traceable S-parameter data sits within the device and is read directly into the PicoVNA software over its USB control and power connection.Īs for any vector network analyzer, for best accuracy, a calibration is performed before a measurement with the same sweep span and frequency steps as the measurement. Where a third party has supplied a calibration kit S-parameter data file, please ask us about the possibility of conversion to Pico format. It can be loaded into the software, which will correct for these errors and those of the instrument during a calibration.Īlternatively, you can use a third-party calibration kit whose ‘model’, electrical length, parasitic values, and polynomial coefficients you can enter into the software and then save in Pico. This standard-form data is a traceable and accurate record of measured errors for the calibration kit. In some instances, only a single calibration kit may be required.Īs you would expect, the Pico calibration kits are individually serial-numbered and supplied with S-parameter data. ![]() ![]() The PicoVNA 3 software supports a comprehensive range of calibration modes to address single or dual-port workload with male, female or mixed-gender interfaces, all with the best achievable accuracy (least uncertainty). ![]()
