The '''Tektronix 2A61''' is a differential amplifier plug-in for the [[560-series scopes | 560 series oscilloscopes]], [[introduced in 1963]]. | The '''Tektronix 2A61''' is a differential AC amplifier plug-in for the [[560-series scopes | 560 series oscilloscopes]], [[introduced in 1963]]. It has independently switchable low frequency and high frequency limits. The low frequency limit can go well below 1 Hz, but it can't go to DC. | ||
