Pre-Amplifier

The measurement system sensitivity can be greatly improved with a preamplifier, which brings several advantages:

  • With a low-noise amplification before the spectrum analyzer input, the signal/noise ratio can be significantly increased.
  • The higher sensitivity allows the user to widen the spectrum analyzer resolution bandwidth (RBW), resulting in faster sweeps and measurements.
