Abstract
Abstract A digital multimeter and associated circuitry provides a high speed conversion, at precise increments, of analog input signals to a digital format while measuring and analyzing the input signals. Means are provided for correlating low speed measurements having relatively high resolution with high speed measurements having relatively low resolution.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
141 words
A high speed signal measuring and analysis system in association with a digital computer, comprising: signal Measuring means including command logic means and signal processing means connected to the command logic means and controlled thereby so as to be responsive to input signals for providing a signal corresponding to a predetermined range of the input signals; a controller connecting the computer and the command logic means and enabling the computer to control the signal measuring means to measure analog input signals; an analog to digital converter; switching means connecting the signal processing means to the converter; the controller connecting the computer to the switching means and enabling the computer to control said means to pass the measured signals to the converter; and the controller connecting the converter to the computer for transferring the converted signals to the computer for analysis thereby.
Claim 2
Dependent Claim
141 words
A high speed signal measuring and analysis system in association with a digital computer, comprising: signal Measuring means including command logic means and signal processing means connected to the command logic means and controlled thereby so as to be responsive to input signals for providing a signal corresponding to a predetermined range of the input signals; a controller connecting the computer and the command logic means and enabling the computer to control the signal measuring means to measure analog input signals; an analog to digital converter; switching means connecting the signal processing means to the converter; the controller connecting the computer to the switching means and enabling the computer to control said means to pass the measured signals to the converter; and the controller connecting the converter to the computer for transferring the converted signals to the computer for analysis thereby.
Claim 3
Dependent Claim
53 words
A system as described by claim 1, including: a clock connected to the converter for initiating conversion cycles in time ordered sequence; and the controller connecting the computer to the converter and enabling the computer to control the switching means to transfer the time ordered converted signals to the computer for analysis thereby.
Claim 4
Dependent Claim
47 words
A system as described by claim 1, wherein the signal measuring means includes: a digitizer connected to the signal processing means for digitizing the signals therefrom; and the controller connecting the digitizer to the computer for controlling the digitizer to transfer the digitized signals to said computer.
Claim 5
Dependent Claim
26 words
A system as described by claim 3, wherein: the command logic means is connected to the digitizer for controlling said digitizer to digitize the processed signals.
Claim 6
Dependent Claim
31 words
A system as described by claim 1, wherein the signal processing means includes: a first signal processor responsive to input signals; and a second signal processor responsive to reference input signals.
