    • 品牌: SCHWARZBECK

           The BBV9743B is a high gain, low internal noise, general purpose broadband preamplifier. The wide frequency range up to 6 GHz allows measurements according to CISPR 22. Due to the high gain and low noise figure, system noise is nearly independent of other components including cables and receivers. These characteristics make the BBV9743B very useful for measuring the very low limits required by CISP25. In this case it will be connected directly to the antenna.

           The amplifier has two stages. The first stage uses an ESD-protected MMIC to prevent defects caused by accidental electrostatic discharge. However, preamplifiers are generally ESD sensitive devices, so it is very important to discharge the coaxial cable before connecting. This is a necessary precaution to protect extremely small semiconductor structures operating in the microwave frequency range.

           It must be noted that for the measurement of pulsed signals, the use of preamplifiers is generally not recommended, and any wideband preamplifier is not suitable for EMC measurements of wideband pulsed spectrum.

            The BBV 9743 has an aluminum housing and uses Type N flange connectors. A standard wall plug power supply with a +12 V DC output can be used. Switching power supplies are not recommended as they may cause higher interference levels.

           Internal protection circuits prevent internal components and receivers from being damaged by voltage spikes by slowing down the rising and falling edges of the power supply. Receivers, analyzers or batteries can also be powered by these instruments if they can provide 0.12A/12V current.
