Panorama mid -frequency

The adjustable bandwidth in the adjustable number, the maximum 40MHz panoramic mid -frequency display, can allow users to observe the changes in the transient spectrum in the medium bandwidth in real time.

Frequency scanning

The frequency scanning mode is the main user's fixed channel interval of radio service monitoring. Users can flexibly set the scanning frequency range and frequency step pace, and set different scan variables for different signals.

Discrete scanning

Special settings can be made for each discrete frequency band, including starting, termination frequency, step/resolution, and threshold, which provides convenience for users who often monitor certain fixed discrete frequency bands.

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.

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.
