Architecture 
SBIR’s 4000 Series blackbodies put the temperature measurement and calibration electronics in the blackbody head rather

than in the control electronics package. With this approach, temperature measurement information from the blackbody

to the controller is serial digital data rather than an analog temperature sensor signal. The result is significantly improved performance:

lower noise operation, more stable temperature control, improved immunity to EMI, and an easier integration task for the test equipment engineer.

High Temperature Range 
The emitting surface of the blackbody can be controlled at temperatures up to 600°C

High Accuracy and Stability 
The microprocessor-based temperature controller is designed for optimum accuracy and stability. A high resolution enhanced

PID temperature servo provides zero drift and low jitter control of the emitting surface’s temperature.

Ease of Calibration 
Calibration is fast and easy. All adjustments can be made directly from the front panel or through the remote interface.

Calibration points are independent of each other, allowing the user to touch up a single calibration point.
