An oscilloscope to sequentially store, process and display an electrical input signal according to various signal events and characteristics. The oscilloscope is physically and functionally modular having both selectable hardware configurations from among various 'plug-in' modules and selectable processing and display features chosen from among a predetermined selection by software control contained, in part, within the plug-in modules. The particular control settings, as well as a representation of the signal itself, is recorded on a removable storage device, such as a magnetic disc. High frequency signals are sampled, digitized and stored in a high speed intercascaded signal memory, independent from the program and data memory associated with the oscilloscope signal processing.

Modular computing oscilloscope with high speed signal memory

An oscilloscope having multiple controls, wherein control functions are selected from a plurality of functions. Controls are located adjacent to the oscilloscope display which indicate the control parameter label and control parameter values. The control parameter selection is implemented by software program control.

Oscilloscope control

In a sampling digital oscilloscope means operable to measure the time period from the occurrence of a trigger signal to the onset of signal sampling period so that commulatively stored samples of a repetitively sampled signal visually coincide, producing a clear, jitter-free signal image. Moreover, the trigger signal is also produced according to a hold-off mode to allow the user to evaluate the results of processing the sampled signals by the digital oscilloscope before adding new data samples. In addition, a triggered update of stored data by new signals is provided, which is further controllable via an arm/disarm control to interrupt realtime updating of signals, allowing the user to observe signal changes as they occur.
