摘要：An emission can be obtained from a sample in response to excitation using a specified range of excitation frequencies. Such excitation can include generating a specified chirped waveform and a specified downconversion local oscillator (LO)
frequency using a digital-to-analog converter (DAC), upconverting the chirped waveform via mixing the chirped waveform with a specified upconversion LO frequency, frequency multiplying the upconverted chirped waveform to provide a chirped excitation signal for exciting the sample, receiving an emission from sample, the emission elicited at least in part by the chirped excitation signal, and downconverting the received emission via mixing the received emission with a signal based on the specified downconversion LO signal to provide a downconverted emission signal within the bandwidth of an analog-to-digital converter (ADC). The specified chirped waveform can include a first chirped waveform during a first duration, and a second chirped waveform during a second duration.
