TekBox TBMDA1, TBMDA2 Modulated Wideband Driver and Power Amplifiers
The TBMDA series modulated wideband amplifier create an inexpensive signal source for immunity testing of electronic components and products. The amplifiers can be driven by the tracking generator output of spectrum analyzers. 4 models with different frequency ranges and technical specifications are available.
