Abstract
Abstract The total number of occurrences of pulse heights are stored in a multichannel storage device and are displayed in the form of a spectrum. At least one generated reference pulse is provided for identifying a portion of the spectrum to be analyzed. The pulse heights and the generated reference pulse are processed by the same equipment so that to analyze a selected portion of the spectrum the required settings of the base line or gain control or any other parameters which are sensitive to pulse height are found by using the generated reference pulse display lines as a guide.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
A method of analyzing a spectrum representing pulse heights and the total number of occurrences of said pulse heights, said method comprising the steps of: storing a first spectrum in a plurality of storage channels, each channel corresponding to a different pulse height in the first spectrum; generating at least one reference pulse; adjusting the height of said reference pulse to correspond to an end point of a selected portion of the first spectrum; and storing a second spectrum representing those pulse heights and the total number of occurrences of each pulse height which occur in said selected portion of the first spectrum in a greater number of storage channels then previously used to store the first spectrum, thereby increasing the resolution of said selected portion.
Claim 2
Independent Claim
126 words
A method of analyzing a spectrum representing pulse heights and the total number of occurrences of said pulse heights, said method comprising the steps of: storing a first spectrum in a plurality of storage channels, each channel corresponding to a different pulse height in the first spectrum; generating at least one reference pulse; adjusting the height of said reference pulse to correspond to an end point of a selected portion of the first spectrum; and storing a second spectrum representing those pulse heights and the total number of occurrences of each pulse height which occur in said selected portion of the first spectrum in a greater number of storage channels then previously used to store the first spectrum, thereby increasing the resolution of said selected portion.
Claim 3
Dependent Claim
221 words
Apparatus for analyzing a spectrum representing pulse heights and the total number of occurrences of said pulse heights, said apparatus comprising: a detector to receive applied signal for producing pulses of heights and occurrences of said pulse heights representative of the applied signal; an amplifier with a variable gain control capable of amplifying pulses applied thereto; generating means for generating at least one reference pulse representative of an end point of a selected portion of the spectrum to be analyzed; a mode selector connected to the amplifier for applying thereto pulses from one of said detector and generating means; first converting means for converting the heights of pulses applied thereto into corresponding digital pulse height value; a biasing circuit connected to the amplifier for varying the base line of the amplified pulses and for applying the resulting pulses to the first converter means; second converting means connected to the first converting means for converting the digital pulse height values into analogue values representative of one coordinate of a point on a spectrum and for converting the corresponding total number of occurrences into analogue values representative of the other coordinate value of a point on a spectrum; and display means connected to said second converting means for displaying the generated reference pulse and said coordinate values of a point on a spectrum.
Claim 4
Dependent Claim
221 words
Apparatus for analyzing a spectrum representing pulse heights and the total number of occurrences of said pulse heights, said apparatus comprising: a detector to receive applied signal for producing pulses of heights and occurrences of said pulse heights representative of the applied signal; an amplifier with a variable gain control capable of amplifying pulses applied thereto; generating means for generating at least one reference pulse representative of an end point of a selected portion of the spectrum to be analyzed; a mode selector connected to the amplifier for applying thereto pulses from one of said detector and generating means; first converting means for converting the heights of pulses applied thereto into corresponding digital pulse height value; a biasing circuit connected to the amplifier for varying the base line of the amplified pulses and for applying the resulting pulses to the first converter means; second converting means connected to the first converting means for converting the digital pulse height values into analogue values representative of one coordinate of a point on a spectrum and for converting the corresponding total number of occurrences into analogue values representative of the other coordinate value of a point on a spectrum; and display means connected to said second converting means for displaying the generated reference pulse and said coordinate values of a point on a spectrum.
Claim 5
Dependent Claim
89 words
Apparatus as in claim 2 wherein the second converting means comprises a digital to analogue converter connected to the display means and first converting means to convert the digital value of the generated reference pulse to a corresponding analogue value for display by said display means as the generated reference pulse display line and to convert the digital values of the pulse heights and the corresponding total number of occurrences of said pulse heights to corresponding analogue values representative of the coordinate values of a point on a spectrum.
