ADC ANALYZER FUNCTIONS
A number of functions can be performed on the data collected
by the FIFO evaluation board. These functions are represented
by the row of buttons under the pull-down menus. The same
functions also can be accessed under the Analyze pull-down
menu. A description of each button is listed below.
TIME DOMAIN
AVCC: Analog voltage level, set under Config > Power Supply
(for display purposes only)
DVCC: Digital voltage level, set under Config > Power Supply
(for display purposes only)
Encode: ADC clock rate (MSPS), set under Config > FFT
Analog: Calculated analog input frequency (MHz)
Min: Minimum output code produced by the analog input
Max: Maximum output code produced by the analog input
Range: The range of the codes produced by the analog input
Average: Average value of the codes; may be interpreted as the
common mode
F/S: Full-scale code range, equal to 2
bits
Samples: Number of samples taken, determined by FFT
Configuration (Config > FFT)
CONTINUOUS TIME DOMAIN
FFT
AVCC: Analog voltage level, set under Config > Power Supply
(for display purposes only)
DVCC: Digital voltage level, set under Config > Power Supply
(for display purposes only)
This function displays a reconstruction of the
captured data in the time domain. Several values are
listed to the left of the signal, including
This function displays a continuous reconstruction
of the captured data and is also useful for trouble–
shooting. Click the STOP button to end the
continuous display.

HSC-ADC-EVALA-SC/HSC-ADC-EVALA-DC
Encode: ADC clock rate (MSPS), set under Config > FFT.
Analog: Calculated analog input frequency (MHz). In IF
sampling applications, the analog input is calculated back to the
first Nyquist zone. Note that the encode rate must be set
properly in the Config > FFT menu.
SNR: Signal-to-noise ratio (dB)
SNRFS: Signal-to-noise ratio full scale (dBFS)
UDSNR: User defined signal-to-noise ratio (dB)
NF: Noise figure (dB)
SINAD: Signal-to-noise and distortion (dB)
Fund: Level of the fundamental (highest) tone (dBFS)
Image: Level of image (nonharmonic) spur (dBc). Note that
Image is valid only when using demultiplexed ADCs
Second: Level of the second harmonic (dBc) of the
fundamental
Third: Level of the third harmonic (dBc) of the fundamental
Fourth: Level of the fourth harmonic (dBc) of the fundamental
Fifth: Level of the fifth harmonic (dBc) of the fundamental
Sixth: Level of the sixth harmonic (dBc) of the fundamental
WoSpur: Level of the worst nonharmonic spur
THD: Total harmonic distortion (dBc)
SFDR: Spurious-free dynamic range (dBc)
Noise Floor: Level of the noise floor (dBFS)
Samples: Number of samples taken, determined by FFT
configuration, set under Config > FFT
CONTINUOUS FFT
AVERAGE FFT
CONTINUOUS AVERAGE FFT
This function displays an average of a user-specified
number of FFTs. Configure the number of FFTs
under Config > FFT. The default value is 5.
This function displays a continuous average of a
user-specified number of FFTs. Configure the
