Digital stroboscopic receiver TMR 7112, TMR 7120, TMR 7140

Ultra wideband (UWB) digital sampling oscilloscopes can be used to observe and measure parameters, to store and analyze repetitive signals, as well as to transfer the above signals and results to other external devices via network.

Application

Registration, parameters measurements and analysis of the UWB signals.
Video and radio pulse reflectometry of the UWB devices.
S- parameters measurements of various active and passive UWB devices.
Logic circuits analysis.
Antenna measurements.
Radar cross section (RCS) measurements.

Main features

• DC up to 40 GHz bandwidth.
• Two input channels.
• External and internal triggering.
• Possibility to measure at the zero dead time using oscilloscopes’ internal reference clock.
• Fully automatic calibration.
• Possibility to manage and transfer data via Ethernet network.
• Possibility of external SVGA display and printer connection.
