Santa Barbara Infrared's cavity blackbody is built around a new and innovative cavity construction that significantly improves the uniformity and slew rate of the cavity, improving test accuracy and reducing test times.

Additionally, this new product incorporates the advantages of SBIR's breakthrough Smart Blackbody™ architecture. The design of the Smart Blackbody creates a system with inherently more stable and accurate temperature control. Additionally, foolproof blackbody interchangeability, high immunity to EMI, ease of calibration, and non-critical cabling all make the Smart Blackbody an easy-to-integrate component into a large test system.

These advanced systems are designed for ease of use and maximum reliability. SBIR's Model 4100 blackbody is the ideal choice for high temperature applications where high performance is a requirement.

Superior Uniformity and Speed
The unique cavity construction of the Model 4100 preserves the high emissivity of traditional cavity blackbody designs, but greatly improves the uniformity and slew rate of the system. Cooling rates are markedly faster, significantly reducing test times.

Smart Blackbody™ Architecture
SBIR's Smart Blackbodies put the temperature measurement and calibration electronics in the blackbody head rather than in the control electronics package. With this new architecture, 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.

The calibration of the blackbody head is independent of the controller, so heads and controllers can be swapped without recalibration.

High Temperature Range
The cavity temperature range extends from 50°C to 1000°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. Temperature corrections are made "closed case", without internal trims, adjustments, or reprogramming of EPROMs. 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.

Built In Test (BIT)
An extensive BIT assures that the blackbody is functioning properly during use. BIT is automatically invoked on power up, and a continuous background (transparent to the user) BIT is performed during operation.

IEEE Std. 488 Interface (GPIB)
The thorough implementation of the ANSI/IEEE Std. 488.1-1987 allows computer control of all blackbody functions, calibration, and optional features such as target wheels and illuminators. (Option G)

RS-232 Serial Interface
An optional serial interface provides computer control of all blackbody, calibration, illuminator and target wheel functions. (Option S)

Aperture and Filter Wheels
A manually-operated aperture wheel is included with the blackbody. Motorized wheels are available to enable multiple apertures or filters to be rapidly and precisely positioned in front of the blackbody. Selection can be made from the front panel of the controller or via the optional remote interface (IEEE 488 or RS-232).

Modulator
A mechanical chopper can be used to modulate the blackbody radiation. Dynamic range of the chopper is 1000:1. A variety of blade sizes and speeds are available. The modulator can be controlled from the front panel or through the remote interface.

Rack Mounting
The blackbody controller is designed for bench-top or standard 19 inch rack use. Rack mount ears are included with the instrument. A rack slide kit is also available.

Handheld Remote Panel
An optional remote control is available. All instrument front panel functions can be accessed using this handheld unit. It is connected to the temperature controller with a 10 foot cable.
