Introduction：
The BBV 9748 is a broadband preamplifier manufactured by Schwarzbeck, Germany and authorized by EUTTEST Shenzhen for sales, quotation and after-sales service. The amplifier can amplify measurement signals by more than 29dB in the frequency range of 10MHz-8GHz. The design uses an external power supply cable to power the amplifier, and is equipped with an aluminum enclosure and an N-flange connector as the signal output port.
Attention:It is generally not recommended to use the preamplifier BBV9748 to measure pulsed signals. This broadband noise is typical of many EMC measurements. This means that any broadband preamplifier is not suitable for EMC measurements of broadband pulse spectra.
