'Cobham is pleased to announce the launch of the TETRA Base Station Test Option for the 8800SX Digital Radio Tester and the 3550R Digital Radio Test System, "said Lyndon Zielke, senior product sales engineer for Cobham Avcomm." With this option, customers There is now a cost-effective, lightweight and flexible test solution outside the 3920B to enable on-site TETRA base station testing including transmitter and receiver testing. "
Transmitter testing at TETRA base stations involves measuring many of the modulation-related important parameters, including RMS error vector magnitude (EVM), peak EVM, residual carrier, frequency error, and signal power. In addition to these measurements, The user can also graphically display the modulation process via a constellation diagram that shows the accuracy of TETRA base station modulation clearly and intuitively by cumulatively displaying the phase and amplitude of each 'symbol point' of the demodulated signal. The symbol point information is decoded The basis of digital information is the key to the modulation process.
Field testing of TETRA receivers is also a key feature of TETRA base station testing.The TETRA standard defines a method of generating standard TETRA BS T1 test signals that users can use to measure the sensitivity of TETRA base station receivers by calling these standard test numbers.
