EASY-MCA 2k or 8k Channel Multichannel Analyzer

EASY-MCA 2k or 8k Channel Multichannel Analyzer
  • Compact stand-alone MCA
  • Two available versions in 2k or 8k resolution
  • Fast (<2 µs) conversion time
  • Includes Dead-Time Correction Logic Inputs (Busy and PUR)
  • Gate Input Provided
  • The easy to use and powerful MAESTRO software is included
  • Fast, convenient USB2 connectivity

EASY-MCA interfaces to a PC via a USB2 cable. This compact MCA is stackable and portable, and no PC option slots are needed. Each EASY-MCA has memory capable of holding the complete spectrum. You have the option of 2k channels of resolution which can be switched to 1k or 0.5k channels or 8k channels of resolution which can be switched to 4k, 2k, 1k, or 0.5k channels.

    EASY-MCA will accept inputs from a shaping amplifier for Pulse Height Analysis (PHA). In addition to the Input signal, EASY-MCA accepts an ADC GATE input, a (Pile-Up Rejection input (PUR), and a BUSY input used by the live-time correction circuits. A single computer subject to USB-2.0 speed of data transfer can control multiple units using USB ports or a powered USB hub.

    PERFORMANCE
    ADC
    The ADC includes sliding scale linearization and <2 µs dead time including memory transfer.
    INTEGRAL NONLINEARITY ≤±0.025% over the top 99% of the dynamic range.
    DIFFERENTIAL NONLINEARITY <±1% over the top 99% of the dynamic range.
    GAIN INSTABILITY ≤±50 ppm/°C.
    DEAD TIME CORRECTION  Extended Live-Time correction according to the Gedcke-Hale method.
    USB INTERFACE  The USB 2.0 to PC as data transfer speeds up to a maximum of 480 Mbps.

    INPUTS and OUTPUTS
    INPUT
    Accepts positive unipolar, positive gated integrator, or positive leading bipolar analog pulses in the dynamic range from 0 to +10 V; +12 V maximum; semi-Gaussian-shaped time constants from 0.25 to 30 µs, gated-integrator-shaped time constants from 3 to 30 µs, or delay-line-shaped with widths >0.25 µs. Zin = 1 kΩ, dc-coupled. No internal delay, BNC connector.
    ADC GATE Optional TTL input with computer selectable Coincidence mode, Anti-coincidence mode, or Off. Signal must occur prior to and extend 0.5-µs beyond the peak of the pulse; Zin = 1 kΩ. BNC connector.
    PUR Pile-up rejection input; accepts TTL signal; signal must occur prior to peak detect. Zin = 1 kΩ. BNC connector.
    BUSY Busy input used by live-time correction circuits. Accepts TTL signal; signal must occur prior to peak detect. Zin = 1 kΩ. BNC connector.
    POWER Positive 12 V with up to 8 W power capacity. Mains supply with cable is supplied with the EASY-MCA.
