RF Test Card 18 Function Modules for Vector Network Analyser Calibration Learning

RF Test Board with 18 Function Modules This RF test board brings together eighteen practical function modules on a single compact card, making it a versatile companion for anyone learning to use a vector network analyser or antenna analyser. Designed with beginners in mind, it offers a hands-on way to explore how spectrum and vector analysers behave across different circuit configurations, without needing a bench full of separate test pieces. Built-In Filter Demonstrations The board includes a useful selection of filters for practical study. A shortwave low-pass filter operates at 30 MHz, an FM high-pass filter at 100 MHz, a commonly used SAW bandpass filter at 433 MHz, and a video ceramic band-stop filter at 6.5 MHz. These give you the chance to observe real filter responses and compare how each type shapes a signal. Circuit and Calibration Practice For learning about impedance and network behaviour, the board provides RLC series and parallel circuits containing resistors, inductors and capacitors, along with combination circuits. It also includes open, short and load calibration circuits, plus an attenuation circuit, so you can practise the calibration steps that form the foundation of accurate analyser measurements. Ready to Use The card comes with two UFL patch cables, so you can connect it to your equipment straight away. Each module is built with reliable components, and the board itself is lightweight and well suited to carrying between workbench, classroom or field use.
