The Tektronix 7A22 vertical plug-in is a DC coupled differential amplifier with excellent common-mode rejection characteristics and high gain for low level applications. It is designed for use in Tektronix 7000 Series oscilloscopes.
The DC offset capability of the 7A22 allows the display of very small low-frequency signals containing a large DC component, at deflection factors not possible with AC coupling. The vertical deflection range of the 7A22 is from 10 µV to 10 V. The high and low frequency -3 dB points can be selected at the front panel to set the bandwidth of the instrument. This means that for low frequency applications, the signal-to-noise ratio can be improved by restricting the bandwidth of the 7A22. The bandwidth selection and excellent drift-with-time characteristics are ideal for applications that require stable, low deflection factor, and low noise measurements.
