7A12 Dual Trace Channel Amplifier

Der Tektronix 7A12 ist ein Zweikanal Verstärker Einschub mit 120 Mhz passend für die 7000 er Serie.

Internal gain and compensation circiuts are automatically switched to the setted V/DIV deflection factor. The amplifier can handle a DC offset of at least +/-500 DIV for viewing low AC signals in the presence of a high DC voltage.
