The FEE serves as a coupling unit for a detector array (via tec5 preamplifier) or a Spectral Sensor to a PC Interface Electronics. The electronics contains the array readout control logic and the ADC to digitize the sensor’s analog video signal.

The circuitry of the tec5 FEEs is designed to provide adequate dynamic range and signal stability when used with tec5 preamplifiers and supported arrays. With quartz-stable clocks for the arrays and on-board power supply filtering, up to true 15 bit single shot performance can be achieved.

The following FEE versions are currently available: FEE-HS for Si NMOS PDAs and Carl Zeiss MMS Spectral Sensors, readout time 1.4 ms for a 256 pixel PDA, 15 bits A/D conversion FEE-1M for CCD, NMOS and InGaAs PDAs and Carl Zeiss MCS or PGS Spectral Sensors, 16 bits A/D conversion, readout time down to 0.52 ms for a 512 pixel PDA

Mechanical product versions:

	FEE-xxx/STD with 40-pin interface connector for use with the tec5 PCI Interface Electronics PD-PCI01V1
	FEE-xxx/EMB with 36-pin board-to-board interface connection for use with tec5 USB interface electronics PD-USB01V1 or customer DSP interfacing
