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: ≤±50ppm/°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. Z_in = 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; Z_in = 1 kΩ. BNC connector.

PUR: Pile-up rejection input; accepts TTL signal; signal must occur prior to peak detect. Z_in = 1 kΩ. BNC connector.

BUSY: Busy input used by live-time correction circuits. Accepts TTL signal; signal must occur prior to peak detect. Z_in = 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.

INDICATOR

ADC: Indicates activity for the ADC

SOFTWARE CONTROLS

(Operates with included MAESTRO-32 – see MAESTRO-32 data sheet for details.)

ADC LLD: Computer controlled from 0 to 100% full scale.

ADC ULD: Computer controlled from 0 to 100% full scale.

PRESETS

REAL TIME/LIVE TIME: Multiples of 20-ms.

REGION OF INTEREST: Peak count/Integral count.

DATA OVERFLOW: Terminates data collection when any channel exceeds 2³¹–1.

PEAK UNCERTAINTY: Stops acquisition when the statistical or counting uncertainty of a user-selected net peak reaches the specified value.

NUCLIDE MDA: Stops data collection when the value of the Minimum Detectable Activity (MDA) for a user-specified MCA reaches the specified value.

LIVE TIME CORRECTION: Gedcke-Hale method.

GATE: Coincidence, Anti-Coincidence, Off.
