- Supports CW (continuous wave) operation with modulation off.
- Built-in AM modulation (1 kHz, 80 % depth) for immunity test signals.
- Built-in pulse modulation (PM) (1 kHz, 50 % duty cycle).
- Can generate 217 Hz pulse modulation with 12.5 % duty cycle to simulate mobile phone TDMA noise.
- Ideal to drive RF near-field probes, TEM cells, and conducted test setups for immunity pre-compliance.
TBMDA3B
Modulated Power Amplifier
The Tekbox TBMDA3B is a modulated wideband RF power amplifier designed to act as a cost-effective RF power source for EMC immunity testing and RF measurement applications. It is driven by the tracking generator output of a spectrum analyzer and delivers high output power across a wide frequency range, making it ideal for conducted and radiated immunity testing using near-field probes, CDNs/BCI probes, or TEM cells.
