The SpectroAnalyzerTM is a compact single or dual-channel counting instrument used for gamma counting, and is also available with a 1024-channel MCA. It contains a precision pulse height analyzer and high voltage supply, both microprocessor controlled.

The pulse height analyzer setting is accomplished through amenu and selects an energy region of interest. When the proper high voltage is applied to the detector, the PHA is calibrated directly in keV. Optional spectrum/MCAincludes auto-calibration.

Output signals from the pulse height analyzer are totaled by the scaler, which can operate in either a preset count or preset time mode, and background count is automatically subtracted. Efficiency can bemeasured or entered, and activitycan be displayed in disintegrations perminute (DPM).

Resolving Time:

Onemicrosecond pulse pair. The overall resolving time of the scaler is limited by the input circuits and the necessary integration time in the detector for adequate pulse height resolution.

Time:

Themicroprocessor-controlled timer indicates elapsed time up to 1000minutes.

PresetTime:

Time can be preset to any number up to 1000 minutes using themenu.

PresetCount:

Number of counts from100 to 10million can be preset by using themenu.

Background:

Automatic subtraction of background count.

Digital Rate Meter:

Indicates 0-10 million counts per minute with automatic change of range.

Pulse Height:

Five energy ranges from 500 to 2000 keV in steps of 500 keV are provided.

Window Setting:

1) Upper and lower leveldiscriminator independently controlled from 0 to 100%.
2) % window. Lower level is set as the reference in keV’s. Windowis set as the% of this reference.
3) Symmetricalwindow. Lower level is set as the reference in keV’s. Windowis set symmetrical about this reference.
