2400/2500 SERIES ELECTRONIC POSITION ANALYZERS
Signal processing and readout electronics. For use with Quantar Technology's Imaging Detectors.

Model 2401B		Position Analyzer Two-axis (X and Y), high speed (4 microsecond dead time per event) pulse position analyzer. Base units include X and Y analog only position outputs (see Digitized Output options below). Complete with 4 channel charge-sensitive preamp/shaper and cables. Operates on 120/240 VAC, 50/60 Hz.
		Preamp Options (must specify either option 001/EM or 002/EP):
		Option 001/EM: Preamp configured for use with standard spatial resolution (2 MCP) sensors
		Option 002/EP: Preamp configured for use with high spatial resolution (3-5 MCP) sensors
		Digitized Output Options Select digitized output option according to number of digitized position data points (accumulating bins) desired across active diameter of sensor. Recommend using at least 2X (oversampling) as many digitized data channels as available resolvable elements from sensor (e.g. for standard resolution (100 resolvable element) sensor, use 8-bit (256 channels) digitized output option). Higher-resolution digitized output results in longer total dead time per event and, therefore, lower maximum counting rate capability.
		Option 008/EC: Add 8-bit (256 channel) Digitized Output. Adds digitized output to both X and Y axis position outputs. No additional dead time relative to basic model.
		Option 009/EE: Add 9-bit (512 channel) Digitized Output. Adds digitized output to both X and Y axis position outputs. Increases dead time to 6 microseconds per event.
		Option 010/EJ: Add 10-bit (1024 channel) Digitized Output. Adds digitized output to both X and Y axis position outputs. Increases dead time to 10 microseconds per event.
Model 2502A		Position Analyzer Two axis (X and Y), ultra-high-speed (300 nsec dead time per event) position analyzer. Complete with preamps. Capable of output count rates approaching 1 million counts/sec (see dead time curve). Uses flash-type ADC; 8-bit (256 data bins) per axis digitization only. Analog outputs for driving real time analog XY (scope) monitor. Differential linearity (effective digitized bin-to-bin width variation of up to ±50% using full 256 channels, less with 128 or 64 channels per axis); may require digital (software-based) flat-field correction in quantitative applications. Consult factory for details. Requires 3300 Series MCP/RAE Sensor equipped with special option 002/SH (Model 3390A, 3392A and 3394A). Some applications (concentrated point or line images) may benefit from use of high bias current (HOT) MCPs in place of standard MCP's. Includes 19" wide, 5" high rack mount module with separate preamp/processor module, 2" x 5" x 7" (50mm x 125mm x 175mm).
