    • 描述: The OAM302 plug-in system transmits analog signals over a fiber-optic link at frequencies ranging from 1 kHz to 1 GHZ and distances up to 1 km.
    • 品牌: TESEO

      TESEO's high-frequency plug-in modules and remote appendages are optical fiber communication links for the transmission of high-bandwidth analog signals in harsh environments affected by electromagnetic interference, noise or high voltage. A plug-in system consists of the following: a basic module suitable for plugging into the MOCS-MF / MFD mainframe, a two-wire optical cable for signal and control, a battery for power supply, shielded generator and a battery charger.

      Each plug-in system is an independent optical channel that can have different frequency bandwidths up to 1 GHz. It can handle the full range of data transfers for pulse testing. It provides researchers and engineers with a comprehensive technical solution to safely transmit uncorrupted data in EMP, EMC and high voltage tests and tests. Each plugin can be managed individually via the μprocessor-control system within the host.

      The OAM302 plug-in system transmits analog signals with a frequency range of 1 kHz to 1 GHz and a distance of up to 1 km through an optical fiber link. The MOCS-MF/MFD main unit can insert six OAM302P plug-in basic units to provide six independent optical channels. System settings and status are displayed on the LCD graphics of the host MOCS-MFD, and all functions can be used and managed through the MOCS-MFD LCD keyboard and embedded GPIB-RS232 interface. During start-up the base unit is automatically detached from the input port of the remote appendage, the maximum attenuation is selected, providing the operator with the possibility to check the function of the channel.

      The small size, battery-powered accessory unit OAM302S can be placed close to the signal monitoring point and combined with a preamplifier and a step attenuator, both of which are programmed by the base unit. The OAM302S can withstand pulsed electromagnetic field strengths exceeding 100 kV /m without being damaged, and the performance does not change in a wide range of environments. It can work continuously for more than eight hours, and can be charged with the accessory battery charger in a short time. It can also be remotely set to standby to save battery power, it will turn off when the battery power is low to ensure correct operation, and also automatically upload information requesting autonomy for 1 hour. Each accessory unit contains an accurate calibration signal generator for periodic checking of system gain, which is maintained by an automatic gain control circuit.
