DATA TYPES OVERVIEW
VisualAnalog components transfer information through wires.
The wires themselves can carry any type of data, but most
component inputs have limitations on what types of data they
can accept. Most components that have an output pass a certain
type of data to the next component.
You can pass any data type to the Data Grid component which
displays an important portion of the data type. For example,
when the Data Grid displays Real Waveform Data, it displays
the list of samples.
REAL WAVEFORM DATA
Real waveform data consists of an array of real samples along
with the sample frequency.
COMPLEX WAVEFORM DATA
Complex waveform data consists of an array of complex
samples (I and Q) along with the sample frequency.
REAL FFT DATA
Real FFT data consists of an array of data that is the FFT result
of real waveform data, along with the sample frequency.
COMPLEX FFT DATA
Complex FFT data consists of an array of data that is the FFT
result of complex waveform data, along with the sample
frequency.
ANALYSIS DATA
Analysis data consists of analysis results along with graph data
and formatting information. This type of data can behave dif­
ferently depending on the component that outputs it. Normally,
this data type is passed straight to a Graph component because
that component displays all the pertinent information. If you
send this data to a Data Grid component, it displays the analy­
sis results portion of the data only.
VALUE COLLECTION
Value collection consists of parameter and value pairs.
Components use this data type to display information.

NUMERIC VALUE
Numeric value contains only a floating-point number. However,
some components treat this number as an integer. The Average
and Peak Hold components both output a numeric value to
indicate when their current sequence is finished. The Stop and
Graph components both can use this value for a control input.
See the Components Overview section for more information
about the use of numeric value.
TONE LIST
The Tone Generator outputs the tone data type. The tone list
contains frequency, phase, and amplitude information about the
tones generated.
Note that two numeric formats can occur within VisualAnalog
when using the waveform types. These are normalized data
(which the majority of processing components use) and integer
data.
The ADC Model, ADC Data Capture, and the FIFO4.x
Interface components are all output integer data. Follow these
components with an Input Formatter component to normalize
the data.
The Pattern Saver and Pattern Loader components can support
either data format as needed by the application. When loading
a vector file, if the format is uncertain, manually examine it to
determine how to process the file. Integer format should be
obvious as either text-readable integers or hexadecimal values,
and normalized data format appears as text-readable floating-
point numbers. Note that VisualAnalog only assumes hexadecimal
format for files with a .hex extension. To input hexadecimal
values, rename the extension to .hex.
Finally, the DPG Interface always expects integer type format.
If the waveform is not already in this format, precede this
component with an Output Formatter component.
See the Components Overview section for more specific
information on the requirements of each component.
