It is also possible to channel the audio output to an ASIO (Audio Stream
Input/Output) device, if it is available in your system. This feature makes it
possible for an ASIO device to bypass the Windows audio processing layers
and access the receiver’s audio output directly, with the lowest possible
latency and eliminating any artifacts introduced by the computer’s operating
system.

Show Measurements
The Test and Measurement functions of the Excelsior receiver make it
possible to indicate the ADC input level (in percentage of the entire ADC
range), Frequency error of the received signal (assuming the receiver is
tuned to the correct frequency), AM modulation depth (for AM-modulated
signals), Frequency deviation (for FM-modulated signals), SINAD (signal-
plus-noise-plus-distortion to noise-plus-distortion ratio) and THD (total
harmonic distortion):

For SINAD and THD, the test frequency is assumed to be 1 kHz.
Note that this function is also conveniently duplicated by the information

Show Data Rates
The Show Data Rates display shows the various internal data rates of the
entire G39DDC receiver system. This may be useful especially for debugging
of installation problems:
