ASPec-927-Dual-MCB - ORTEC - #1

Text version of the page

ASPEC-927 Dual MCB ORTEC® PERFORMANCE ADCs: Successive-Approximation type with sliding scale linearization. MAX RESOLUTION: 16k: 16,384 channels, software selectable as 16,384, 8,192, 4,096, 2,048, 1,024, and 512. DEAD TIME PER EVENT: 2 ìs 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: Software selectable for extended Live-Time correction according to the Gedcke- Hale method or ZDT Live-Time corrections which monitors the counting rate and adjusts the dead-time for fluctuating counting rates. DATA MEMORY: 512 kb. USB INTERFACE: Interfaces to a PC via USB 2.0. Data transfer speed is 480 Mbps maximum. INPUTS AND OUTPUTS INPUTS: 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 ìs, gatedintegrator- shaped time constants from 3 to 30 ìs, or delay-line-shaped with widths >0.25 ìs. Zin = 1 kÙ, dc-coupled. No internal delay, BNC connector. ADC GATE: Optional TTL input. Computer selectable Coincidence mode, Anti-coincidence mode, or Off. Signal must occur prior to and extend 0.5-ìs beyond the peak of the pulse; BNC connector. Zin = 1 kÙ. PUR: Pile-up rejection input; accepts TTL signal; signal must occur prior to peak detect. Zin = 1 kÙ. BNC connector. BUSY: Busy input used by live-time correction circuits. Accepts TTL signal; signal must occur prior to peak detect. Zin = 1 kÙ. BNC connector. At Last, an Economical Dual-Input Multichannel Analyzer System in a Single Width NIM Module. • Dual fast (1.25-ìs) ADC and memory in a single width NIM • Dual 16k ADC’s, compatible with MAESTRO-32 for Windows MCA emulation program • Live time corrections including ZDT • PUR, BUSY, and GATE inputs • Interfaces via USB-2.0 • True live display of data • Synchronize this unit with your sample changer or process control • On board memory allows fast downloads to your PC • Two inputs in a single wide NIM The ORTEC Model ASPEC-927 interfaces to a personal computer via the USB-2.0 interface and includes MAESTRO-32 emulation software. Each ASPEC-927 is presented in a single width NIM chassis and includes two independent 16k ADCs, and 512 kb of memory. The successiveapproximation 16,384 channel ADCs with 1.25-ìs conversion time has selectable conversion gain settings for 8,192, 4,096, 2,048, 1,024, or 512. Dead time corrections can be accomplished using the Gedcke-Hale Extended Live-Time method or the ZDT method. A single computer subject to the USB-2.0 speed of data transfer can control multiple units using USB-2.0 hubs. Specifications
