Clean Drive Signals for Amplifier Tests

Amplifier characterization uses a controlled radio frequency stimulus to drive the amplifier input while output power, gain, and distortion are measured across defined frequency and level conditions. The setup typically includes an analog signal source, calibrated cabling or switching, attenuation, and a measurement receiver, signal analyzer, or power meter to monitor the amplifier output.

The signal source is configured for the target carrier frequency and input power, then swept or stepped to evaluate small-signal gain, output power response, and gain compression. For nonlinear distortion testing, two precision source tones can be applied to measure intermodulation products and estimate third-order intercept performance under controlled drive conditions.

Precision Amplifier Test Solution

Amplifier characterization requires a stable radio frequency input signal with repeatable frequency control, accurate output level, and low unwanted spectral content. This solution combines precision analog signal generation with amplifier test workflows for gain sweeps, output power measurements, gain compression analysis, and intermodulation distortion testing. Engineers can configure carrier frequency, input power, sweep behavior, and modulation conditions to reproduce bench, design verification, or manufacturing test scenarios. The setup supports repeatable amplifier characterization by reducing uncertainty from source instability, level variation, phase noise, and spurious content.
