Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.

Quad RF Driver
-
The Quad RF Driver contains four independent RF channels, each with an RF synthesizer, variable attenuator, and 1W power amplifier. The RF signal can originate from either the internal synthesizer or an external source via SMA input. All channels have independent frequency, phase, and gain settings and can be operated in one of two modes. The “Wideband” mode operates from 35MHz to 2GHz with a 3.472KHz resolution; over this range the frequency roll-off is approximately 0.5dB/100MHz. “Int-N Phase Adjust” mode allows the user to set and maintain a fixed phase relationship between all four channels. This mode is designed to operate between 300 and 460MHz with a 2MHz resolution. Two additional inputs are provided for an external frequency reference and digital modulation.

Mid-Range Gas Filter Correlation CO Analyzer
Model N300M
-
Teledyne Advanced Pollution Instrumentation
The Model N300M is a microprocessor-controlled analyzer used to determine the concentration of carbon monoxide (CO) in a sample gas. The analysis method is based on the Beer-Lambert law.The N300M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.
