When not using a direct power cord, it is necessary to ensure that the input voltage of the broadband amplifier is+5V. When using a direct power cord, it is necessary to ensure that the input voltage of the direct power cord is+5V

PLA030 Pulse limiter

The main function of a limiter is to limit the output signal amplitude to a certain range, which means that when the input amplitude exceeds a certain reference value, the output amplitude will be limited to a certain amplitude and will no longer change with the input voltage. The applicable frequency range is 50kHz~1GHz.

RFS003 Radio frequency switch

The applicable frequency range of the RF switch (RFS003) is 9kHz~300MHz. When the RF switch is turned off, the isolation degree is 34dB (minimum value). This RF switch is mainly used in conjunction with our company's limiter.

The current injection probe is mainly used for conducting sensitivity measurement; The interference signal is injected into the signal cable or power line of EUT to simulate external interference to determine the conduction sensitivity of EUT.

CDN016-M3 Coupling decoupling network

The coupling/decoupling  network consists of two parts: coupling and decoupling.The main  function of decoupling is to prevent useful signals from leaking to the power supply terminal (AE port) and to prevent disturbing signals from interfering with useful signals. The function of coupling is to transmit the disturbance signal of the device under test (EUT port) to the signal port.(RF port) in order to measure by measuring instruments, or transmit the electromagnetic disturbance signal of RF transmitter to the tested equipment.
