NOTE
These characteristics assume that the waveguide mixer is connected to a cw signal source and that the PEAKING
control is adjusted for maximum signal amplitude. The signal must be stable (not frequency modulated more than
the resolution bandwidth); otherwise, frequency response specifications cannot be met.
