Abstract
Abstract A multi-channel pulse monitoring and indicating system uses a programmed digital computer system to control sampling and display, in time measurable context, of multiple pulse timing functions of peripheral devices and/or service processors. The sampled functions are stored electronically and also visibly presented on a retentive CRT display unit associated with the computer system. A keyboard associated with the computer permits a service operator to interact with the program and select the service processor which is to be monitored and the time measurement parameters of the system; with selection prompting indications presented by the program to the operator via the display unit. An example is given of the time-referenced indication of feeding, punching, reading, printing and stacking functions of a record card processing unit.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
Apparatus for monitoring and indicating teSt conditions of multiple test points in service processors connectible to a main processor comprising: a measuring oscillator in the main processor; a strobe pulse generation unit in the main processor coupled to the measuring oscillator for generating strobe pulses; a measure data storage and translation unit; a gating circuit operated by said strobe pulses to sample measure value data into said storage and translator unit; and means for displaying the sampled measure values in a time measurable context upon the occurrence of each sensing pulse.
Claim 2
Dependent Claim
91 words
Apparatus for monitoring and indicating teSt conditions of multiple test points in service processors connectible to a main processor comprising: a measuring oscillator in the main processor; a strobe pulse generation unit in the main processor coupled to the measuring oscillator for generating strobe pulses; a measure data storage and translation unit; a gating circuit operated by said strobe pulses to sample measure value data into said storage and translator unit; and means for displaying the sampled measure values in a time measurable context upon the occurrence of each sensing pulse.
Claim 3
Dependent Claim
30 words
An arrangement according to claim 1, in which the display means comprises a cathode ray tube with an image retention feature subject to affording continuous display of the desired image.
Claim 4
Dependent Claim
60 words
An arrangement according to claim 2 in which the cathode ray tube unit and the controls of the measuring processor are organized into an alphanumeric display medium for displaying measuring and identifying information in columns and rows, the rows defining the lines for indicating individual measure value functions and the columns indicating time positions of discrete measure value sample indications.
Claim 5
Dependent Claim
24 words
An arrangement according to claim 3 in which said columns are scanned for writing new measure value information in synchronism with said strobe pulses.
Claim 6
Dependent Claim
78 words
An arrangement according to claim 1, including address channel and measure value channel connections between the service processors and the measuring processor, in which each service processor includes an address decoder and measure value output gating network coupled between the address channel and measure value channel and responsive to decoding of distinct address signals uniquely associated with the respective service processor to transfer the respective measure value function signals to the measuring processor via the measure value channel.
Claim 7
Dependent Claim
46 words
An arrangement according to claim 5 in which each service processor unit includes a voltage limiter network for limiting the voltage of measure value signals transferred to the measuring processor in order to eliminate the effects of spurious fluctuations in said signals and the external ambient.
Claim 8
Dependent Claim
53 words
An arrangement according to claim 5 in which each service processor includes a service oscillator tuned to a frequency which differs from the measuring oscillator frequency by a multiple of a predetermined small fraction of the measuring oscillator frequency whereby the two oscillators have a predetermined small phase drift relative to each other.
Claim 9
Dependent Claim
37 words
An arrangement according to claim 7 in which the frequency offset of the service oscillators is utilized to provide time measurable indication of discrete samples of measure value signals having durations much shorter than the strobe pulses.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 1 in which the measuring processor is programmed to control and maintain the sampling sequence and the display function.
Claim 11
Dependent Claim
17 words
Apparatus according to claim 9 in which the program is provided in the form of a microprogram.
Claim 12
Dependent Claim
33 words
Apparatus according to claim 9 in which the program is changeably stored in the measuring processor and is read into the program store of the measuring processor from a tape cartridge or disc.
Claim 13
Dependent Claim
35 words
Apparatus according to claim 9 in which the program is arranged to control the monitoring, sampling and time measurable display of plural test points in each of a plurality of discretely addressable service processor units.
