Der Tektronix 7A13 ist DC gekoppelter
Differenz Komparator. Ein Differenz Verstärker für
schnellere Signale.
Mit ihm lassen sich im Differenzbetrieb kleinere Signale
darstellen die z.B. auf einer höheren Gleichspannung aufliegen.

Ältere Versionen vom
7A13 Verstärker hatten anstatt der LED Anzeige eine mechanische
Anzeige.
Single Channel DC coupled differential comparator
amplifier Excellent
differential amplifier in particular for fast signals. The older version of the 7A13 amplifier has instead of the LED
display a mechanical display
