Accelerometers

Columbia Research Laboratories
The force balance accelerometer has a classical critically-damped, second-order frequency response. There is no peaking in the response but simply a smooth roll-off above the natural frequency. This property along with the excellent characteristics of the "HP" torquer design makes Columbia accelerometers the best choice for demanding applications where precise DC and near-DC measurements are needed in demanding shock and wide band vibration environments. Columbia force balance accelerometers are available to cover virtually all applications. Low noise, high output units can be used for seismic structure motion studies while miniature, high range versions are optimum for measuring more violent high G environments encountered in many industrial, aircraft and missile applications.

PXI/PXIe RF Multiplexer, Dual 4-Channel, 3GHz, 75Ω, SMB
42-832A-002
Multiplexer Module
The 40-832A-002 (PXI) and 42-832A-002 (PXIe) are 75 Ohm 4 to 1 RF multiplexers with 2 banks in a single slot. They have been designed to exhibit low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. Each MUX has been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The design of the 40/42-832A minimizes the injection of noise and unwanted signals into the signal path by careful attention to the mechanical and electrical design.
