AM/FM Receiver Validation

Amplitude modulation and frequency modulation receiver validation requires a stable RF carrier, controlled modulation settings, and a receiver measurement path. The signal generator applies the carrier at the target frequency and output level while modulation depth, modulation rate, or frequency deviation is adjusted for each test condition.

The test works by applying known analog modulation to the receiver input and monitoring demodulated output, received signal strength, distortion, sensitivity, or response thresholds. Engineers can step carrier power, carrier frequency, and modulation parameters to evaluate receiver behavior across expected operating conditions.

AM/FM Receiver Validation Solution

Analog receiver validation requires a controlled RF carrier with repeatable amplitude modulation or frequency modulation settings. The solution uses compact analog signal generation to stimulate the receiver input while modulation parameters and RF output level are adjusted across the test range. Keysight analog signal generators support receiver testing with high-purity signal generation, low phase noise, low spurious output, wide output power range, and fast frequency and amplitude switching. These analog signal generators also have modulation capabilities such as amplitude modulation, frequency modulation, phase modulation, and pulse modulation.
