The Keysight 8447F is a combined instrument containing both the 8447D Preamplifier and the 8447E Power Amplifier in a single package. Operating over a frequency range of 0.1 to 1300 MHz, it provides gain and power to overcome systematic RF losses, drive high-power devices, and improve the dynamic range and sweep speed of measurement systems like network analyzers.
