Preamplifier for Tektronix EMC pre-compliance
EMI-PREAMP (Com-Power PAM-103 offered by Tektronix)
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.
