The EMI-PREAMP preamplifier is intended for improving measurement system sensitivity during EMC compliance testing. With a frequency range of 1 to 1000 MHz and a gain of 33 dB, it amplifies the signals that were previously hidden below the noise floor of the EMI receiver so that they can be seen and measured. The preamplifier has a gain variation of ±3 dB for the entire frequency range to reduce measurement errors. It can be powered by the rechargeable NimH batteries included when an external power source is not available.
