Electron Multiplication (EM) Standard Image Sensors
EM (Electron Multiplication) is a technology that uses on-chip gain in the charge domain to effectively eliminate read noise from an image sensor. This enables advanced ultra-low light applications that require extreme sensitivity at fast frame rates. Examples include life science applications such as single molecule detection, super resolution microscopy and spinning disk confocal microscopy along with physical science applications such as nanotechnology imaging, Bose Einstein condensates and soft X-ray spectroscopy, and astronomy applications such as adaptive optics and lucky imaging. The inclusion of an additional conventional output allows further flexibility for applications such as true 24 hour surveillance.

Audio Generator
AG-51
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.

Shunt Voltage References
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.
