In the input power range of 5 dBm to 0 dBm, the output power of the tracking generator can be boosted up to a maximum of 5W.
The TBMDA4 modulated wideband power amplifier is designed to create a low-cost signal source for immunity testing of electronic building blocks and products, driven by the output of a spectrum analyzer's tracking generator. It can boost the output power of the tracking generator up to 5W within an input power range of -5 dBm to 0 dBm. It ideally complements the TBMDA3, which covers a frequency range of 10 MHz to 1 GHz from 100 kHz to 50 MHz. The TBMDA4 is ideal for driving Tekbox near-field probes to find sensitive spots in electronic circuits, creating electric fields of up to 550 V/m when driving the TEM cell TBTC0, and 300 V/m when driving TBTC1. When driving TBTC2 or TBTC3, it generates 100 V/m. The test signals for immunity testing can be CW, AM, or PM modulated, providing built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, the TBMDA4 can also generate a 217 Hz signal with a 12.5% duty cycle to simulate mobile phone TDMA noise.
