Spec Sheet Description
Antenna Measuring System
With the ANTENNA MEASURING SYSTEM, learners can analyze and characterize single antennas and arrays, starting from the UHF band up until microwaves, through simple yet effective experiments:
- Impedance matching: RL and SWR
- Radiation: antenna gain, 2D/3D radiation diagrams and planes of polarization
- Antenna Arrays
Complete system composed of:
- 1 Transmitter, including:
- PLL dual-band synthesized RF generator (1GHz and 10GHz)
- Support for reference antenna
- 1 Receiver, including:
- Synthesized PLL RF reception system
- Motorized rotating support for D.U.T (Device Under Test)
- Data acquisition system, that both acquires the RF signal and controls the motorized system
- USB port to connect the system to a supervising PC
- Several types of antenna for 1 GHz and 10 GHz bands
- 1 Directional coupler to measure the Return Loss
- 1 supervision and control software, to configure and control the system. It enables to analyze the received data and represent them graphically on a PC screen
