RF Power Amplifier, see also seperate brochure In most cases two or three RF power amplifiers. and two different antennas are needed Transmitting Antenna s. see also seperate brochure, The software controls the level of the signal to cover the whole test frequency range It. generator output for each test frequency would be very time consuming to change. This signal level is amplified by the power the cabling between the different amplifiers Broadband antennas like our model ALX 4000. amplifier output in order to generate the antennas and power meters manually For which cover the whole frequency range from. required test field strength around the EUT this purpose software controlled switching 30 MHz up to 4 GHz may be used as a single. It depends on the testing setup the distance relays are used as they work much faster and antenna solution The advantage of these. between EUT and antenna 1 m 3m and without any damage to the RF cables which antennas is that they can be used for immunity. the test level test field strength might be caused by changing the connections tests as well as for emission measurements. 3 10 100 200 V m or special requirements manually Furthermore cabling mistakes In order to save amplifier power and costs it is. whether an amplifier output of 10 W 30 W cannot occur recommended to use so called double stacked. 200 W 2 kW is required Normally field log periodical antennas for immunity tests. strength of 10 V m with 1 kHz 80 AM like our model AXL 80 This antenna type offers. can be obtained with a 250 W amplifier in a a much higher gain compared to the above. testing distance of 3 m described broadband antennas For our systems. we recommend the following antenna types,Antenna types.

A field strength meter is necessary for the, While testing the field strength probe is replaced measurement of the uniform area and the As an alternative horn antennas can be. by the EUT A power measurement during the test generated field strength It should be of used in the GHz range if a max uniform. runs assures that the EUT is actually exposed to the small size in order to avoid disturbances of the. requested test condition Thus a directional coupler field by the physical size of the field strength area of 1 0 m is sufficient. is connected with the amplifier output A power meter itself The data transfer from the anechoic Emission Immunity tests Immunity tests. measuring device determines the forward and chamber to the control room should be. reverse power up to 6 GHz or higher Both are via fibre optic link It makes sense to integrate. stored and recorded by the control software For the fibre optic converter directly into the RF Cabling. this purpose directional couplers are connected with sensor because long conductive cables could. The RF cabling is a very important part, the amplifier output or the built in directional influence the accuracy too The test frequency. of a radiated immunity test system as the, couplers of our EMC test control unit ECU 3 6 range from 80 MHz to 3 or 6 GHz should at.
