Power modules
G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation

RF Test Spectrum Measurements over CPRI
Integris 3000
Most modern cell tower network configurations place the Remote Radio Head (RRH) at the top of the tower and the baseband unit(BBU) at the bottom of the tower. While this configuration is advantageous for both computational efficiency and mitigation of RF loss across the cable, it means the only place along RF can be accessed is at the top of the tower. This forces field technicians to have to climb the tower to measure and debug RF noise problems.
