Can you generate a chirp with Moku:Lab's waveform generator?
Frequency chirp with Waveform Generator
Moku:Lab's Waveform Generator can generate a chirp signal from 1 ms to 1 ks with the sweep modulation function.
If a shorter duration is desired, you can prepare a chirp waveform in the .CSV or .MAT file format, upload it to Moku:Lab's Arbitrary Waveform Generator and output it via the custom waveform option.
