TPA-N-PRE Datasheet TPA-N-PRE Pre-Amp • Measurement of low-power signals TPA-N-PRE Preamplifier The TPA-N-PRE preamplifier accessory for the MDO4000 and MDO3000 Series Mixed Domain Oscilloscopes provides 12 dB nominal gain, further lowering the already low noise floor in the MDO4000 and MDO3000 Series. This allows you to pull very small signals out of the noise in low-amplitude signal applications. For example, in the following screenshot we are measuring a noise floor of -114 dBm (-154 dBm/Hz) without the TPA-N- PRE preamplifier. It appears that there is only noise present. In the screenshot below, we've turned on the preamplifier. Notice that the noise floor has dropped to -124 dBm (-164 dBm/Hz). As a result of the noise floor dropping significantly, we're now able to see a -116 dBm signal present at 900 MHz that was hidden in the noise without the preamplifier.
