The '''Tektronix Type 190A and 190B Constant-Amplitude Signal Generator''' is a sine wave source that uses feedback to provide a signal whose amplitude does not vary with frequency or with the impedance of the load, within stated limits. | The '''Tektronix Type 190A and 190B Constant-Amplitude Signal Generator''' is a sine wave source that uses feedback to provide a signal whose amplitude does not vary with frequency or with the impedance of the load, within stated limits. | ||
The 190 was designed by [[Rodgers Jenkins]]. | |||
The frequency range is 350 kHz to 50 MHz. The amplitude measurement is made using a peak-to-peak (envelope) detector in an external attenuator head that is connected to the main unit by a special cable. | The frequency range is 350 kHz to 50 MHz.
