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.

Keysight Technologies
The Keysight Technologies, Inc. U9391C comb generators were developed to provide precision phase calibration, for non-linear measurements using the PNA-X nonlinear vector network analyser (NVNA), referenced to the National Institute of Standards and Technology (NIST) standard. Additionally, the comb generators can be used to calibrate PNA and PNA-X network analyzers for phase and delay measurements of frequency converters without requiring reference or calibration mixers.

Electro-Optical Products Corp.
An external clock signal, to provide an ultra stable modulating optical beam motion [sub] system. The system can be used as a "stand alone" unit, in the laboratory, or can be incorporated into a larger instrument/system. The chopper is ONE FIXED FREQUENCY, picked from the range of 5 Hz to 20 kHz. The chopper is a small size, light weigh, low cost and long life device. It requires low power drive electronics and does not radiate electromagnetic interference (EMI). It has high frequency stability and high amplitude stability. The chopper is IR, VIS and UV and high vacuum capable. Reference signal and position output available.

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.
