Tekbox TBMDA3 - Modulated Power Amplifier
TBMDA3 - Modulated Power Amplifier
The TBMDA3 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 -5dBm…0dBm, it can boost the output power of a tracking
generator up to 5W. The TBMDA3 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
TBMDA3 provides built in modulation capability to generate 1 kHz AM or PM
signals. In PM mode, the TBMDA3 can also generate a 217 Hz Signal with 12.5%
duty cycle in order to simulate mobile phone TDMA noise.
