5.
From the file browser, select the model of interest.
When the model is selected, information about that device
is filled in on the ADC Modeling form. Note that the
amount of jitter, assumed at the time of characterization,
automatically inserts in the External Jitter box on the
Input tab. The model also returns a default Output Mode
which is defined either as Offset Binary or Twos
Complement. This setting automatically sets through the
Config > FFT menu. If using a real part along with a
model, note the correct Output Mode setting. If the
windowing function under the Config > Windowing menu
is set to None, a Coherent Sampling window opens. If you
are in modeling mode and use this function, the calculated
frequency inserts in the Analog In box on the Input tab
Step 5a:
6.
Select the Input tab. From this tab, you may select the input
stimulus of either a single or dual sine wave, the input
signal level relative to the converter range, the input
frequency, the signal offset, the signal range, external clock
jitter and external analog dither. If two tone is selected, you
also may specify the second tone. For the most accurate
results, both signals should be in the same Nyquist zone.

The Model is now fully configured and evaluations may
begin. Any of the documented features of ADC Analyzer
may be used for testing the virtual evaluation board as if a
real evaluation board were connected. In addition, the
virtual evaluation board supports sweeping of the analog
input level and frequency.

To switch back to evaluate a real product, it is only required
to specify the buffer memory by selecting Config > Buffer
and select HSC_ADC_EVAL from the drop down list.
