tomato-picovna

tomato driver for Pico Technologies PicoVNA network analysers.

This driver is a wrapper around the vna library, which is part of the PicoVNA 5 SDK. As such, the driver needs to be supplied with a location of the SDK using the settings file of tomato.

Supported functions

Capabilities

• linear_sweep for performing a sweep of the reflection coefficient using linearly spaced points

Attributes

• temperature, the temperature of the PicoVNA device, RO, float
• bandwidth, the filter bandwidth for the sweep in Hz, RW, float
• power_level, the power amplitude of the sweep in dBm, RW, float
• sweep_params, a list of sweep parameters defining the frequecies of the start, stop, and step for each component of the sweep, in Hz, RW, float
• sweep_nports, the number of ports to be swept, selecting a reflection (= 1) or transmission (= 2) experiment, RW, int
