MIXER
Mixer performs a complex frequency shift of the input wave­
form and produces real or complex waveform output. For
complex input, the complex output option is required. The
translation frequency may be positive or negative.
OUTPUT FORMATTER
Output Formatter converts normalized VisualAnalog data to
integer formats used by the DPG and the pattern saver.
Possible output formats include Gray Code, Unsigned Offset,
Two’s Complement, and Signed. Adjust the output bit
resolution and alignment as necessary.
PEAK HOLD
Peak Hold computes the peak data from the provided data. The
indicator on the component shows how many iterations have
occurred out of the total number of comparisons. To set the
total number of averages, click Settings. To reset the peak hold
series, click Reset.
The Peak Hold component is most efficient when running a
continuous update. A running peak hold occurs and the peak
hold continues until either the user stops the canvas or the
number of runs equals the terminal count. In the second case,
Peak Hold repeats another series of iterations unless a stop
block halts the canvas programmatically.

The Peak Hold component has two outputs. The top output
is the running peak FFT data. The second output is a numeric
value that indicates when the peak hold reaches its terminal
count by outputting a nonzero value.
A Stop component (see the Stop section) can use the terminal
value from the Peak Hold component to halt a continuous
update. In this case, when the Stop component receives a non­
zero value and halts the canvas, the last update presents the final
peak hold.
Other components can use the terminal value as an indicator
to perform processing only on a nonzero value. See the Graph
section for more information on how to use the Graph compo­
nent with this terminal value.
POWER/PHASE
Power/Phase converts data from an FFT into magnitude and
phase format. Click Power/Phase to open the options form,
allowing the formats to be set.
