miniVNA Tiny Plus2 User Manual

Portable USB vector network analyzer

miniVNA Tiny Plus2

Product Overview

The professional VNA-PC software is used for data analysis and processing. The signal generator function is integrated. The measurement range is 1MHz~3000MHz, and the S parameter measurement of S11 and S21 is supported.

The miniVNA Tiny Plus2 has the software open-circuit, short circuit, load, and straight-through calibration functions (the corresponding calibration components need to be prepared or purchased by the customer).

The software supports data export in multiple formats, including JPEG, Excel, ZPlots, S1P, S2P, and PDF.

Windows, Linux, and Mac

The miniVNA Tiny Plus2 : CNC aluminum shell (red upgrade).

-The upgraded version uses the CNC aluminum shell to enhance the high-frequency anti-interference capability, improve the heat dissipation of the equipment, improve the consistency and reproducibility of repeated measurement and different time measurement, and make the measurement more accurate and reliable.

** This product does not contain other accessories. If you need to use it, purchase it separately.

Precautions

Note 1: If the precision is high, you are advised to calibrate the device after the device is powered on and calibrate it 15 minutes after the device is powered on. Otherwise, the measurement precision may be inaccurate due to temperature changes.

Note 2: Because the minVNA Tiny Plus2 needs to dissipate heat effectively, do not cover sundries on the surface to ensure good heat dissipation on the surface. Because the surface temperature is high after the device is used for a long time, take protective measures against scalding.

Note 3: Because the USB current of the device is large, you are advised to connect the USB cable to the USB port on the mainboard to increase the reliability of the USB power supply.

Note 4: The USB port of the device must be stable. You are advised to use a fixed or uncommon USB port of the PC as the minVNA Tiny Plus2 port.

Note 5: All legends, scanning results, and measurement quantities in this document are for reference only because of the differences between devices, environments, proofs, and products. The test tools and accessories involved in this document must be purchased by the customer.

Note 6: A similar attenuator must be added to the test amplifier. Otherwise, the device may be damaged.

The miniVNA Tiny Plus2 vector network analyzer must be used in the Java environment. Therefore, you need to install the Java software of version 7.0 or later on the computer. Select the WINDOWS/Linux/MAC system according to the actual situation and install the Java software of the 7u80 version(http://www.eastchip.com/minivnasoft.asp). If the JAVA7.0 or a later version has been installed on the PC, you do not need to install it again. If you need to install the Java of 7u80 or later, download the corresponding version from the official website of Oracle (https://www.java.com/en/download/).

The following uses the Windows 7 (64-bit) system as an example to describe how to install the Java. The file name is jre- 7u80-windows-x64.exe. Run the file as shown in the following figure to complete the installation.
