Audio Data Monitoring View
The audio data monitoring view is discussed in the
following sections.
Receive Audio Data of Channel#
Allows selection of channel to control and view. The
Audio Data Monitoring view allows the generation of
DAC data and the capture and display of ADC data.
Operation of the front panel in Line Monitoring view is
detailed in the following list. See Figure 1.
TX Control
!

!
DAC Waveform: Selects the waveform to be
generated by the DAC. The waveform types are as
follows: dc, Sine, Square, Ramp, and .wav file.
TX Gain (dB): Selects the transmit path gain/
attenuation.
TX Mute: Mutes the transmit path.

Sampling Rate: Sets the sampling rate of the DAA
and performs writes to corresponding registers.
Amplitude: Sets the amplitude of the DAC
waveform in either volts or the units of DAC codes.
The units are determined by the Amplitude Units
control.
Frequency: Selects the frequency (Hz) of the
waveform to generate. The actual waveform
frequency may vary slightly from the entered value.
This variation is due to the requirement to fit an
integer number of samples into the transmit buffer.
The control is updated to reflect the actual waveform
frequency generated. The equation for calculating
the frequency of the waveform is as follows:
Actual Frequency = round ((Waveform Frequency/DAC
Sample Rate) x BufferSize) x (DAC Sample Rate/
BufferSize)
