MCA4000 Multichannel Analyzer

MCA4000

Premium Performance at a Price You Can Afford

The MCA4000 is a high-performance multichannel pulse height analyzer.  Packaged as a standalone unit, it features total computer control, excellent performance and flexibility.

The MCA4000 is available in three configurations: 1000, 2000 or 4000 channels of spectrum memory. Each unit also comes with QuantumMCA software for Microsoft Windows, and it is compatible with our optional fully quantitative gamma analysis software package QuantumGold.

The MCA4000 features a 2.7 microsecond successive approximation ADC. With hardware add-one to memory and an on-board 20 MHz processor, there is processing power to spare. Differential non-linearity is less than ±1 percent over the top 99 percent of the range, and integral non-linearity is less than 0.05 percent over the same range. Digital stabilizers are provided for both the gain and offset. Data are stored as 31 bits per channel with an additional 8 bits for ROI information. Flexible live time correction is provided with a choice of simple busy, Lowes, Gedcke-Hale, or external dead time methods.

The MCA4000 is fully computer controlled.  There are no pots to adjust.  Upper level (ULD) and lower level (LLD) discriminators and the ADC zero offset are all computer controlled.  Conversion gain can be set from 250 channels to the maximum for the particular model.

A wide range of presets is available, including live time, real time, integral of all ROIs, integral of selected ROIs, total SCA counts, net ROI statistics, and gross ROI statistics. The MCA4000 has many of the I/O connections you need for configuring any measurement application. External rear panel BNC connections are provided for GATE, REJECT, BUSY-IN, and ADC-INPUT. The polarity of REJECT and BUSY-IN can be programmed from the MCA software. MCA outputs include SCA OUT, PEAK DETECT, and ADC BUSY. The polarity of the PEAK DETECT and ADC BUSY signals can be programmed from the software. A 26-pin DSUB connector is also provided for ROI outputs and digital control signals.

For qualitative analysis, the MCA4000 includes QuantumMCA software at no additional charge. This package features an intuitive, user-friendly interface, as well as a single hardware setup and search utility that establishes communication with PGT multichannel analyzers. Also available is the optional QuantumGold quantitative analysis software.
