PRELIMINARY TECHNICAL DATA
EVAL-AD1555/AD1556
Step 1 Start execution: click on the double-arrows icon to
start execution.
Step 2 Configuration menu: Selects Configuration, Signal
input, PGA gain setting, AD1556 filter selection, power
controls, interface settings.
Display window : displays either Time domain or Frequency
domain or Histogram and/or performance values such as
dynamic range, equivalent input noise level, THD and DC
offset.
Step 5 Display menu : selects Time/Frequency domain or
histogram, controls display parameters ( scales, zoom,
cursor...), and controls outputs ( save to file or print ).
Step 4 Computation menu : COMPUTE launches the
specified computation data process before display, allowing
windowing, software filtering or measurements computation
if desired. Compute sequence should be done again after
changes into computation, sampling, configuration menus.
F3 is the key command for "compute".
Step 3 Sampling menu : after the desired samples number is
selected, SAMPLE launches a sampling sequence. When
complete, "Successful" will appear in the status window. If
not, verify the configuration and the hardware setup. When
the configuration or sampling menu is modified, a sampling
sequence should be done again. F2 is the key command for
"sample". "Continuous" allows continuous running sampling
and computing (F4 is the key command key for "continu-
ous"). "Average" allows the averaging between successive
sampling.
