Notes:
A chopper wheel apparatus to characterize the time response of a nitric oxide detector is described. At low chopping rates, fast Fourier transform analysis of the output signal indicates that the instrument has a response time of about 0.45±0.14 s with respect to a periodic input signal. This detector has an "e-folding" response time of about 0.3±0.1 s to a simple step change in input signal, demonstrating reasonable agreement within experimental uncertainty between the two techniques. © 1999 American Institute of Physics.
