Spinner has developed a digitally-controlled attenuator that is switchable via PIN diodes for mobile communication system measurement and simulation. Frequencies range between 400 and 2500 MHz. The input is N-type, which bears a maximum load of +37 Bm. The input signal is split to two 6 dB outputs which have SMA connections. Measurements in TX and RX operation mode are possible without changing the measurement set-up.
Port 1 to port 2 can be switched in 10 dB steps from 0 through 100 dB. Port 1 to port 3 can be alternated between 0 and 16 dB as desired (all attenuation values relating to basic attenuation). This set-up can be used to simulate the free transmission in mobile communication links.
It is possible, for example, to test and evaluate the behaviour of mobile phones at very low signal reception levels and the required high transmitter power in a measurement cycle. Another option, which helps increase the accuracy of the attenuator, is that the exact attenuation values and temperature coefficient for a certain number of frequency points can be stored in an EPROM. Since these reference values are known, the attenuator can also be used as a calibration element. The memory and a temperature sensor are integrated in the control motherboard. The operating temperature is read out as an analog value. The attenuator is controlled by a TTL signal via a 6 bit data line.
