'''[[7000-series scopes|Tektronix 7000 series oscilloscope mainframes]]''' have one ([[7912]]) or two vertical plug-in slots, and zero ([[7612D]]), one (7xx3) or two (7xx4) horizontal plug-in slots. | |||

Pins are numbered from 1 at the bottom to 38 on the top. | ||
In the following table, (H) indicates signals available in horizontal slots only, (H-A) is horizontal slot A, (H-B) is horizontal slot B, and (V) denotes signals available in vertical slots only. | |||
