Product introduction


PPS Preamplifier Power Supply& Signal Separator is used for giving power supply to preamplifier. Our acquisition card can offer power supply to PA series preamplifier, no need to connect external power supply. Once using our preamplifier and other company’s AE acquisition card to do collaborative testing, it is necessary to connect PPS and power adapter to offer separate power supply to PA series preamplifier, so as to ensure normal usage of the preamplifier.




Two models can be selected: PPS50, PPS2K
