Typical Output Latency
The following oscilloscope image shows an example of the reduced output latency when
using the BlazeX output. In this example, the input signal is a ~500 kHz sinewave that
abruptly changes from 10 mVrms to ~20 mVrms. The output filter is configured as RC,
18 dB/oct., with a 1µs time constant. Notice the BlazeX output begins responding to the
amplitude step change after only 1.7 µs, while the regular X output does not begin to
respond until after 10 µs.
