116 Clear the Air. When Marconi first began experimenting with a spark gap transmitter, he didn’t have to worry about RFI. Nowadays though, everything from household appliances to overhead power lines can pollute the radio spectrum. If you’re dealing with unwelcome noise (QRN) in your shack, there are solutions.

As a vectorial analyzer, it can perform quadrupole measurements of S11 and S21 parameters, with the results displayed and stored as a Smith diagram. Power supply and sof ware upgrades are available via USB interface; an external power supply is not required. Impedance (Z) can be measured from 1 to 1,000 Ω; dynamic range is up to 70 dB. The device can be used as a low power HF generator as well. Other features include SMA connectors for better isolation; ability to export in a variety of formats; full phase measurement; and boot loader for firmware upgrades. The updated miniVNA PRO2 version is a dual port unit as well, with 100 kHz to 200 MHz/10 kHz to 230 MHz frequency ranges. It includes a 1000mAh battery, providing four hours of full-scan operation, and a wireless Bluetooth interface—enhancements that allow you to use the analyzer directly at the antenna’s feedpoint. Other features include impedance range from 1 to 1,000 Ω; built-in USB battery charger; two separate buf ered RF outputs for I/Q for SDR experiments and IMD test with independent 0-55 dB attenuator; extended dynamic range: up to 100 dB for transmission, up to 50 dB for reflection; and user-friendly interface for PC Windows, Linux, and MAC. Both models can be used with optional WiMo 50 Ohm SMA Calibration Kit, which includes one 50 Ω load, one short, and one open.

Af er selecting your analyzer’s “Calibrate” function and attaching the Open, Short and Load calibration standards to the end of a coaxial cable as directed, you can view the “true” characteristics of the antenna under test, as if the analyzer were connected directly to the antenna feedpoint. Open, Short, and Load standards are built into high-quality silver-plated chassis mount SO-239 (UHF female) connectors. DXE-OSL-CAL-SET OSL Calibration Set .....................................................................$65.99 ZERO II VNA Project Board For you DIYers and out-of-the-box experimenters, RigExpert's latest VNA project board is a small, flexible, and low-cost option for hams and hobbyists looking for a measuring device that can be integrated into a project. While it has no keyboard or readout, the ZERO II (100 kHz-1,000 MHz frequency range) comes with an onboard USB port to allow for a connection to a computer to quickly perform common measurements such as resistance, reactance (signed), SWR, and return loss. The ZERO II is compatible with RigExpert AntScope sof ware and can be paired with common Arduino boards for hardware/sof ware projects. Only limited by your imagination, the ZERO II can be used to build an automatic antenna tuner, perform RF circuit or antenna analysis remotely, fine-tune an antenna's driven elements, and much more. REU-ZERO-II ZERO II VNA Project Board ..................................................$100.00 OSL Calibration and Coaxial Adapter Kits These kits combine Chelegance's Open, Short, and Load SMA male calibration standards with three coaxial adapter types; choose the set that mates with your analyzer. Open, Short, and 50 Ω Load are used for analyzers that support automated OSL calibration. Using the included adapters, the calibration connectors can be placed, one at a time, directly on a network analyzer or antenna analyzer. On some analyzers, calibration connectors may be used at the end of coaxial cable to account for the complex impedance changes that connectors and cable lengths cause in RF systems. This process provides the most accurate measurements of the characteristics of the antenna.
