Characterize Frequency Response Across Design Ranges

Frequency sweep testing is used during design to apply a changing-frequency stimulus across a defined range and observe how a circuit responds as the input moves through that range. The setup typically requires a waveform generator to create the swept signal, and a measurement instrument to capture gain, attenuation, resonance, or other response changes as frequency varies.

The swept signal is applied to the device under test while an oscilloscope, analyzer, or other measurement instrument records the output behavior across the sweep. Dual-channel operation can also support related reference or trigger signals when timing alignment or correlated stimulus is needed during design-stage characterization.

Frequency Sweep Design Solution

Performing frequency sweep testing requires a controllable stimulus source that can vary frequency across a defined range while maintaining repeatable output conditions for measurement. Expert Benchtop Waveform and Function Generators support this workflow by generating sweep signals and arbitrary waveforms that can be shaped, sequenced, and replayed during design characterization. Dual-channel output, 120 MHz bandwidth, arbitrary waveform capability, sequencing support, and a 1 GSa/s sample rate make this approach well suited to sweep-based response analysis. This helps engineers observe gain variation, passband behavior, resonance, and roll-off under controlled bench conditions during early design work.
