  • Acoustic Modem Option for Control Module

    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.

  • Measurement System for ESD Protection

    SampleProtect - Oxford Instruments plc

    The SampleProtect measurement system is ready to go, and comes complete with Oxford Instruments’ Cryofree bottom loading cryostat – the OptistatDry BLV, Zurich Instruments’ MFLI Lock-in Amplifier, a specially designed ESD break-out box and high quality measurement grade cables. The patent-pending puck style mounting from Oxford Instruments provides safe installation of your samples. The MFLI 500 kHz Lock-in Amplifier (capable of 500 kHz demodulation as standard) with MF-MD multi-demodulator capability brings the benefits of high performance signal processing at low and medium frequencies. The differential voltage and current inputs of the MFLI are optimised for low noise operation and the high oversampling rate ensures an even better signal to noise ratio. Zurich Instruments’ unique LabOne® control software provides a toolset including an integrated oscilloscope, a spectrum analyser, a plotter and a parameter sweeper.

  • Bench PIM Tester - iBA series

    iBA - 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.

  • High-Density Precision SMU (10 PA, 30 V)

    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.
