What is the main function of fixed attenuator

(1) Adjust the size of the signal in the circuit; (2) In the comparison measurement circuit, the attenuation value of the network under test can be read directly; (3) If some circuits require a relatively stable load impedance, an attenuator can be inserted between the circuit and the actual load impedance to buffer the change of impedance.

If I exceed the maximum input level, will I burn out the fixed attenuator?

This is not recommended as it may cause data distortion or burn down attenuators.

All of HBTE fixed attenuators are tested and specified at 50Ω impedance, can I use them at 75Ω?

It is not recommended. If you need key specifications for the 75 Ω system, please contact our salesman. Our engineers will redesign the internal components for you to meet specific requirements.

Antenna bracket

When testing in anechoic chamber, all kinds of test antennas need to be fixed on the antenna tower. Through the height and angle adjustment of the antenna fixed base of the antenna tower, the test of different frequency bands can be completed. When the antenna is at different height, horizontal and vertical polarization, the test can be carried out. In order to avoid electromagnetic wave reflection caused by metal materials, HBTE provides various antenna fixture made of non-metal materials, which can fix the test antenna to the antenna tower to realize the positioning function of the antenna.
