TBMDA4B Modulated Power Amplifier
Tekbox Amplifiers
Product Description
The TBMDA4B modulated wideband power amplifier is designed in order to create an inexpensive signal source for immunity testing of electronic building blocks and products. It is designed to be driven by the tracking generator output of spectrum analyzers. With an input power range of -20 dBm…-10 dBm, it can boost the output power of a tracking generator up to 5W. With a frequency range from 100 kHz to 75 MHz, it is an ideal complement to the TBMDA3, which covers 10 MHz to 1 GHz.
The TBMDA4B is ideal to drive Tekbox near field probes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 550V/m when driving the Tekbox TEM Cell TBTC0, 300V/m when driving the TBTC1, 150V/m when driving the TBTC2 or 100V/m when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM modulated. Consequently, the TBMDA4B provides built in modulation capability to generate 1 kHz AM or PM signals. In PM mode, the TBMDA4B can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.

TBPS01 EMC Near-field Probes + TBWA2 Wideband Amplifier
Oscilloscope Accessories
Product Description
The TBPS01 EMC near field probes H20, H10, H5 and E5 are magnetic field (H) and electric field (E) probes for radiated emissions EMC pre-compliance measurements. The probes are used in the near field of sources of electromagnetic radiation.They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies.The probes act similar as wide bandwidth antennas, picking up radiated emissions from components, PCB traces, housing openings or gaps and from any other parts that could be emitting RF. The probes are usually connected to a spectrum analyzer. Scanning the probe over the surface of a PCB assembly or housing quickly identifies locations which emit electromagnetic radiation. By changing to a probe with smaller size, the origination of the emissions can be further narrowed down.Additional applications are RF immunity tests by feeding a RF signal into the probe and radiating it into potentially susceptible circuit sections: Furthermore the probes can be used in the field of repair or debugging to track down issues in RF signal chains by contactless measurement of RF signal levels. One more application is non- invasive measurement of RF building blocks such as modulators or oscillators. Frequency, phase noise and spectral components can be measured in conjunction with a low noise preamplifier.The TBWA2/20dB and TBWA2/40db wideband amplifiers are connected between EMC probe and Spectrum Analyzer to increase the dynamic range of the measurements.
