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.

HORIBA, Ltd.
HORIBA Scientific produces a wide range of holographic master gratings from which high precision replicas are manufactured.Using Type IV aberration-corrected monochromator gratings, a single concave grating disperses, collimates, and refocuses the light from the entrance slit onto the exit slit. Wavelength scanning is obtained through a simple rotation of the grating.The groove spacing of these gratings is computer-optimized to produce high quality images with a minimum of astigmatism and coma, even at large numerical apertures. Compared with Czerny-Turner monochromators (equipped with one plane grating, one collimating mirror and one focusing mirror), Type IV aberration-corrected monochromator gratings provide much better light collection efficiency and signal-to-noise ratio.

Teledyne Marine Gavia ehf.
Gavia AUVs can be fitted with the Teledyne Benthos ATM-900 Acoustic Modem. The ATM-900 Series Acoustic Telemetry Modem is the most advanced, multipath and noise tolerant, modem available. They are designed to meet both the high data rate requirements of commercial users, and the higher reliability, lower data rate requirements of the military. The modems employ two modulation techniques: phase shift keying (PSK), which provides the highest bit rate, and multiple frequency shift keying (MFSK), which provides reliability in a multipath environment, or when the modems are required to operate in a low signal-to-noise (SNR) environment. The ATM-910 Series can transmit data using PSK modulation for reception by a Gavia Modem Deckbox, but receives data using MFSK modulation only. MFSK modulation is a spread spectrum modulation process that transmits multiple tones simultaneously.

Kaelus
Passive Intermodulation (PIM) occurs when multiple RF signals encounter defects in materials or workmanship in an RF path. These defects behave like a mixer causing noise to be generated at mathematical combinations of the original carrier frequencies. PIM interference that falls in the receive band of a wireless system elevates the noise floor resulting in high dropped call rates, call blocking, slow data transmission speeds and decreased system capacity.Kaelus is the industry leader in Passive Intermodulation test solutions. Since 1996 Kaelus has supplied RF equipment manufacturers around the world with precision IEC compliant test equipment to perform this critical test. From initial product design through high-volume manufacturing, Kaelus offers a wide range of PIM test solutions that enable equipment manufacturers to quickly and confidently verify the performance of their products.

PZ2131A -
Keysight Technologies
The Keysight PZ2131A is a high-channel density precision source / measure unit (SMU) having 5 channels per module and saving space for a wide range of applications requiring numerous precision power supplies. The narrow-pulse function and fast Digitizer Mode allow the PZ2131A to expand the conventional static DC measurements to emerging dynamic measurements. Its seamless current measurement ranging function eliminates the time it takes to change the range and expands the dynamic range to cover multiple measurement ranges, which reduces test duration. These capabilities make the PZ2131A suitable for applications that require numerous precision power supplies, such as semiconductor reliability tests and integrated circuit (IC) tests. The Keysight PX0107A low noise filter adapter lowers its voltage source noise level, which makes the PZ2131A suitable for noise-sensitive applications such as quantum computing as well.
