  The Tektronix Type 191 Constant-Amplitude Signal Generator produces sine waves whose amplitude remains constant as the frequency is varied, provided the load limitations of the instrument are not exceeded. Front-panel controls indicate the peak-to-peak voltage of these sine waves at the input to a 50 ohm load.
  This instrument is useful for making frequency-response measurements of broadband devices operating in the frequency range from 350 kilohertz to 100 meghertz.
  The characteristics apply over an ambient temperature range of 0° C to +50° C. Warm-up time for the given accuracies is 5 minutes at 25° C ±5° C.
