Riverhawk Company
Displacement Pickups are vibration transducers that incorporate a spring-mass system with eddy-current damping using a frictionless pivot. This pivot is a spring flexure that serves as the ‘spring’ and a moment arm attached to the pivot serves as the ‘mass’, which allows resolutions down to the micro inch range. At frequencies above 50Hz, the mass remains fixed in space and becomes an inertial reference. A transducer within the pickup senses the motion of the mounting base relative to the inertial reference and converts it into a proportional signal. Appropriate damping results in a frequency response flat down to 10 Hz. Note that the pickup senses in only one plane, which is perpendicular to the mounting base.

350C Series -
Venable Instruments
Venable Model 350c is the 3 channel successor to the original workhorse Model 350a/b that launched in 1986 and established Venable Instruments as a market leader. The contemporary 350c Series incorporates a 3rd channel, allowing the user to measure more transfer functions simultaneously with one sweep, such as source and load impedance. The 350c is the only frequency response analyzer in the industry that can measure absolute phase, using a reference channel.

HI-913 -
Metrix
This Hardy Shaker provides the ability to set the amplitude and change the frequency range without the amplitude changing. This automation makes conducting a test easier. A test can be conducted on a vibration transducer and manually recorded. Multiple tests are not saved; for multiple tests use the HI-903 or HI-803 units. The HI-913 is used for testing from 7 to 10,000 Hz, it offers adjustable frequency and vibration levels. This provides a reference source for verifying the accuracy of vibration transducers, connectors, cabling and instruments or instrumentation systems. The HI-913 has a ruggedized suspension system that can support heavy transducers (up to 800 grams - see frequency limits in the manual). The HI-913 has a built-in battery charger that can operate on 120 or 240 VAC. The unit comes in a rugged Pelican case.

Spectronix
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.

SV 111 -
SVANTEK Sp. z o.o.
SV 111 vibration calibrator is the State of the Art instrument designed for human vibration measurements according to ISO 8041. The design of the calibrator is based on the triaxial reference accelerometer and microprocessor controlled shaker. These both features assure excellent stability of the calibration levels and their frequency independently from mass of the testing object, like also indicate improper test object fixing by monitoring of shaker vibration in all three axis simultaneously.
