With its 1dB compression point of +27dBm, it can boost the output power of a tracking generator up to 500mW. The TBMDA2 is ideal to drive near field probes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 170V\/m when driving the TEM Cell TBTC0, 100V\/m when driving the TBTC1, 50V\/m when driving the TBTC2 or 30V\/m when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM. Consequently, the TBMDA2 provides built in modulation capability to generate 1 kHz AM or PM signals. In PM mode, the TBMDA2 can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.<\/p>\n<h3>Features<\/h3>\n<ul>\n<li>CW amplifier (modulation off)<\/li>\n<li>1 kHz, 80% AM modulation<\/li>\n<li>1 kHz, 50% duty cycle pulse modulation<\/li>\n<li>217 Hz, 12.5% duty cycle pulse modulation<\/li>\n<\/ul>\n<h3>Specifications<\/h3>\n<p><strong>Input \/ Output:\u00a0<\/strong>50 Ohm, SMA female<br \/>\n<strong>Nominal supply Voltage:\u00a0<\/strong>5V, typ. 700mA, Mini-USB-B connector<br \/>\n<strong>Maximum supply voltage:\u00a0<\/strong>5.5V<br \/>\n<strong>Maximum input power:\u00a0<\/strong>-8dBm continuous, 0 dBm @ 25\u00b0C for 5\u00a0<strong>minutes max.
