What tests are used for communication equipment testing?
Communication equipment mainly used SDH transmission analyzer, broadband oscilloscope, spectrum analyzer, Ethernet data analyzer, antenna tester, signaling analyzer, spectrum analyzer instrument, notebook computer, network server etc..
Test frequency discriminator: including mixer and local oscillator (auxiliary frequency) frequency, RF signal will be converted to the limit test of broadband amplifier and broadband frequency discriminator, it has the following characteristics: sensitive and accurate enough to match with the emission of airborne power to 1mW low frequency rate; fast enough to display the frequency offset must be DC coupled output.
Power test receiver: used to test the transmitter power of adjacent channels. It includes oscillator, intermediate frequency filter, variable attenuator and level indicator.
