Saelig Releases Modulated Wideband Power Amplifiers for EMC Pre-compliance Testing

Saelig has released Modulated Wideband Power Amplifiers from TEKBOX to provide an economical signal source for immunity testing of electronic circuits and products.

The TekBox TBMDA3 and TBMDA4 can be used to increase the output of a spectrum analyzer’s tracking generator, they are also useful as general purpose wideband RF signal amplifiers. These amplifiers are ideal for driving near-field probes in order to find sensitive spots on electronic circuits, or for creating strong electric fields of up to 550V/m when driving TEM Cells. With an input power range of -5 dBm to 0 dBm, they can boost signal power up to 5W. The TBMDA3 has a frequency range from 10 MHz to 1GHz, while the similar TBMDA4 covers a range of 100 kHz to 50 MHz.

Test signals for immunity testing can be continuous wave or AM or PM modulated by the TBMDA3 and TBMDA4, which both provide built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, they can also generate a 217 Hz Signal with 12.5% duty cycle for simulating mobile phone TDMA noise.
