The 11301 is an analog oscilloscope that is digitally controlled. | |||
Like a typical analog scope, the 11301 has vertical amplifiers, a trigger circuit, | |||
a timebase/sweep, a horizontal amplifier, and a CRT. | |||
Unlike traditional analog scopes, the 11301 contains a significant amount of digital circuitry, | |||
including multiple microprocessors. | |||
The digital circuitry provides several externally-observable features: | |||
* self-test and diagnosis | |||
* self-calibration | |||
* remote control via RS-232 or GPIB | |||
* on-screen menu-based touch screen user interface | |||
Digital circuitry also implements some features that were traditionally implemented with analog circuitry, | |||
e.g., the trigger holdoff is implemented with a counter instead of with a multivibrator. | |||
There are many DAC-generated analog control voltages in the 11301. | |||
