TBAS3 RF 10W attenuator set

Product Overview

The TBMDA1 modulated broadband amplifier is designed to create an inexpensive signal source for resistance testing of electronic components and products. It is connected to a tracking generator in a spectrum analyzer.
With a gain of 1dB + 27dBm, it can increase the output power of the tracking generator to 150mW.
TBMDA1 is ideal for working with near-field probes (as transmitting antennas) to find the sensitive spot of an electronic circuit or to produce an electric field of up to
50 V / m when working with the TBTC1 chamber
25 V / m during operation with TBTC2 chamber
18 V / m when running with TBTC3 chamber

Test signals for immunity testing can be CW, AM or PM. The TBMDA2 generator provides a built-in modulation function in AM or PM 1 kHz.
In PM mode, the TBMDA1 generator, can also generate a 217 Hz signal with a duty cycle of 12.5% to simulate the impact of a cell phone.
