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 ~2 MHz sinewave that
abruptly changes from 10 mVrms to 30 mVrms. The output filter is configured as RC,
12 dB/oct., with a 1µs time constant. Notice the BlazeX output begins responding to the
amplitude step change after only about 1 µs, while the regular X output does not begin to
respond until after 9 µs.
