Hewlett-Packard Models 1200A and 1200B Dual Trace Oscilloscopes are electrically identical, general purpose instruments. Model 1200A is a cabinet version with a built-in tilt stand, convenient carrying handle on top, and feet mounted on both bottom and rear for either bench or upright operation. Designed primarily for rack mounting, the Model 1200H uses only 5-1/4 vertical inches of rack space and has front panel handles for portability. Since all circuitry is solid state, power consumption is only about 50 watts, and a cooling fan is not needed.
