TITLE: TEKTRONIX 7A22 Differential Vertical Amplifier - Untested DESCRIPTION: The Textronix 7A22 is a single channel differential vertical amplifier for the 7000 series mainframes, produced from about 1969 to 1991. Specifications and controls are similar to the 26A2 and the 3A9 from the 560 series but without current probe input or front panel signal output. Remarkably, the 7A22's input sensitivity reaches down to 10 V/Div. Bandwidth is 1 MHz, the upper 3 dB limit can be reduced in 3 steps down to 100 Hz (to eliminate noise, inter alia), and the lower bandwidth can be raised in 10 steps from 0.1 Hz to 10 kHz. A separate control optionally supplies an internal DC voltage to offset the DC signal component. Even in the most sensitive ranges (10 V/Div to 10 mV/Div), common-mode voltage can be ±10 V. Input resistance is 1 M, but for high source resistance DC coupled measurements, one can disconnect the internal gate return resistors of the input FETs, at the disadvantage of disabling the 20 mV/div and higher ranges. CONDITION: Physically it looks fine, but I am unable to test this unit.
