Products/Services for attenuation
Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors. Search by Specification | Learn More about Fiber Optic Attenuators
Instrumentation amplifiers are differential amplifiers that have been optimized for use with DC signals. They are characterized by high gain, high common mode rejection ratio (CMRR), and high input impedance. Search by Specification | Learn More about Instrumentation Amplifiers

Digitally Controlled Attenuators
AKON Inc. offers a line of digitally controlled RF attenuators that operate over the range of 1.0 GHz to 18.0 GHz and can provide attenuation up to 60 dB. Attenuation is flat over the entire band with no suck-outs and remains relatively flat regardless of attenuation setting. Control is single-ended TTL with up to 8 bits of resolution. Response time is typically under 100 nS. (read more)
40-180 Programmable Attenuator Module
The 40-180 Programmable Attenuator Module is available with either one or two independently programmable attenuators in a single width 3U PXI module. Each attenuator uses high reliability mechanical switches to operate binary weight attenuator pads, providing attenuation values from 0 to 63 dB in 1 dB steps. (read more)
Model 3955 170Hz to 25.6MHz GPIB/Benchtop Filter
The Krohn-Hite Model 3955 programmable, dual channel, low-pass filter is the first dual low-pass programmable filter of its kind, covering the wide cutoff frequency range from 170Hz to 25.6MHz with 2 digits of resolution. The 3955 is a 4-pole, maximally flat (Butterworth) filter, with an attenuation slope of 24dB/octave and a stopband attenuation of >100dB referred to 1Vrms input. (read more)
