6.8 GHz Wideband Synthesizer with Integrated VCO
ADF4356
The ADF4356 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. A series of frequency dividers at another frequency output permits operation from 53.125 MHz to 6800 MHz. The ADF4356 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate RF output frequencies as low as 53.125 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable.

Boundary-Scan DIMM Socket Tester
ScanDIMM
Maximizing test coverage is an important piece in test procedure development. Unfortunately, not all designs have the necessary requirements in place to accommodate boundary-scan test methods on memory devices. ScanDIMM digital socket test modules are designed to overcome such limitations when testing DIMM sockets utilizing boundary-scan test techniques.ScanDIMM modules provide the capability to instantly turn any DIMM socket into a fully compliant IEEE-1149.1 device. Integration is as simple as assigning the included BSDL file to the reference designator of the target socket and compiling test vectors.In multi-socket systems, multiple ScanDIMM modules can be linked to provide even greater boundary-scan test depth.

Gas Filter Correlation Carbon Dioxide Analyzer
Model T360
The Model T360 CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T360 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Instrumentation Amplifiers
Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.

Lake Variable Area Flow Meters
Lake Variable Area flow meters, often referred to as rotameters, measure flow rate of a liquid or gas by relating linear displacement of an internal “float” or sharp-edged orifice plate (Lake) to a corresponding flow rate. As flow rate increases, the orifice area that the flow moves through also increases – thus, the term “Variable Area.” Variable Area meters either allow flow through a peripheral orifice formed between a tapered wall and a float as in the traditional rotameter, or an annular orifice and an internal tapered metering pin in the Lake Monitor.
