Voltage Controlled Linearized Attenuators To 16 GHz
-
Pulsar's voltage controlled, PIN diode linearized attenuators are available from 0.25-16 GHz with attenuation ranges of 32 and 64 dB. Each model includes an integrated linearizer, and a driver that controls the attenuation level. This design results in transient free switching between attenuation levels as opposed to the spurious outputs that result when an attenuation value is switched either on or off by a direct digitally controlled attenuator. Transfer function is 8 dB / Volt.

Open Optical Encoders
-
An optical encoder is an electromechanical device which produces an electrical signal output proportional to the linear displacement of a linear guide or the angular position of an input shaft.Open encoders are exposed and feature no external integrated enclosure. The advantages of open optical encoders include the effective elimination of backlash, shaft wind-up (torsion) and other mechanical hysteresis errors.A rotary open optical encoder consists of a position measurement readhead and an accurate rotary scale marked either on the periphery of a ring or on the face of a disc.The readhead measures position by optically sensing the regularly-spaced scale markings and outputs this information as an analogue or digital signal.The signal is subsequently converted into a position reading by a digital readout (DRO) or motion controller.

Linear Bench Power Supplies Local Control, Ultra Low Ripple/Noise
Series MSK
-
Kepco's MSK linear power supplies provide a selection of five models, offering 100 Watts of stable benchtop power. They use a high gain linear (series pass) stabilizer circuit for ultra low noise and low ripple output, good stability, and accurate resettability, and they are MIL-STD-461 compliant.MSK's "Preview" switch (d-c on-off) allows voltage and current to be pre-set with the digital meters displaying the set values. At "d-c off," no voltage is applied to the output terminals and no load current needs to be drawn to set the current limit. At "d-c on," the set voltage is applied to the output terminals, the appropriate mode indicator illuminates and the meters indicate actual voltage and current.
