The Type 536 does not contain trigger and sweep circuitry. In case a 536 is to be used as a conventional oscilloscope, a the Type T timebase plug-in is available.
The 536 contains identical vertical and horizontal amplifiers, with a front panel control to set the two in phase. This allows an equal bandwidth of 11 MHz in both directions. It also has a special CRT with equal bandwidths in both directions. Aside from the amplifiers, the only other circuitry in the entire scope are the power supplies and calibrator.
