DETAILED DESCRIPTION

PicoVNA vector network analyzers are a new range of professional instrumentation from Pico Technology, which designs and manufactures all of its instruments in the UK. A distinctive feature of PicoVNA analyzers is a large set of professional functions at a very low cost for this level.

Among the strengths of the series, which included as standard PicoVNA, it is worth noting: the presence of four independent receivers (Four receiver), the ability to supply a constant voltage (Bias tee) to the central contacts of the measuring ports, measurements in the time domain (Time domain), shift of the reference plane (Reference plane offsetting), exclusion from the measurement results adapters added after calibration (De-embedding) and measuring the compression point of active devices (P1dB). In addition, the PicoVNA 108 can be used to measure frequency mixers.

PicoVNA vector analyzers take up very little bench space and provide excellent visualization of signals on large computer monitors up to 4K resolution (3840 by 2160 pixels). And since all the results go directly to the computer, you do not have to manually transfer them for documentation and storage. As an example, this photo shows the Pico Technology PicoVNA vector analyzer in real working conditions.

Despite their compact size and low cost, PicoVNA analyzers have good accuracy and an impressive set of professional features.

Calibration, verification and connection to the measurement object

As already mentioned, PicoVNA compact electrical network analyzers provide high performance at a low cost. The same applies to the accessories they can be equipped with. Pico Technology makes everything you need at a great price.

To carry out measurements, you will need: at least two phase-stable cables, a calibration kit (one or more), plus adapters for connecting to various types of connectors.

This photo shows the main accessories for the PicoVNA series analyzers. See the full list below on this page in the section Options and accessories. You can find additional information about the selection of accessories for the VNA here, and about the calibration of network analyzers, see special article, which also contains the video.

It is also desirable to equip the network analyzer with a test standard with known parameters, which you will periodically connect to the instrument during operation to verify its accuracy. An example of such a TA430 standard with 25 ohm impedance and SMA(m)-SMA(f) connectors is shown in this photo.

PicoVNA 2 Software

The PicoVNA series vector network analyzers are controlled by the PicoVNA 2 software supplied with the instrument. Compatible operating systems are Windows 7, 8 or 10, and data communication can be via USB2 or USB3 interface.

The software features are standardized in the field of vector analysis and allow you to measure the values of S11, S21, S22, S12, as well as several additional parameters. Measurement results can be displayed on one, two or four separate graphs. Markers, limit lines, and other common features are supported. In separate windows, you work with measurements in the time domain (Time domain), measure the 1 dB compression point, calibrate, and so on.

Please note that the program supports various color schemes, such as light-colored graphs on a dark background, which are more common in network analyzers with a built-in screen. And for documentation and subsequent printing on paper, a color scheme with dark graphs on a white background is better suited. An example of the main window of the PicoVNA 2 control program with such a color scheme is shown in this screenshot.

Before carrying out a series of measurements, it is necessary, using a special reference set, to perform network analyzer calibration. To do this, the PicoVNA 2 program has a separate window, shown in the screenshot below, which contains everything you need for this procedure. It supports both loading a ready-made file with the calibration coefficients of the set used, and manually entering the necessary parameters.

PicoVNA series analyzers standard features include measurement of the 1 dB gain compression point (1 dB gain compression point or P1dB for short) of amplifiers and other active devices. The measurement can be carried out at a single frequency or in a given frequency range.

During the measurement, the PicoVNA network analyzer determines the gain at low input power and then gradually increases the power to find the point where the gain decreases by 1 dB. Below is a screenshot of the corresponding PicoVNA 2 window.

It is known that in various non-linear devices, a change in the amplitude of the radio signal can cause a change in its phase. This type of distortion has a particular effect on the quality of complex digital modulations, in which the amplitude is constantly changing, and the accuracy of maintaining the phase is very important. These types of modulation include, for example, QAM (Quadrature Amplitude Modulation) modulation.

The PicoVNA series vector analyzer software contains a special mode that allows you to measure the effect of the signal amplitude applied to the device under test on changes in its phase. A screenshot of the corresponding PicoVNA 2 window is shown below.

Measuring mixers with the PicoVNA 108 analyzer

The PicoVNA 108 network analyzer model can measure frequency mixers as standard. To do this, in addition to the analyzer itself, you must use an external signal generator, such as Pico Technology AS108 (300 kHz - 8 GHz). It is possible to measure such parameters of mixers: conversion loss (Mixer conversion loss), return loss (Return loss), isolation (Isolation) and compression (Compression).

As an example, this screenshot shows the PicoVNA 2 program window, in which the compression of the studied mixer is measured.
