Enter the new peak to peak voltage using the numeric keys followed
by the ENTER key, or if satisfied with the current voltage press the
DONE function key to bypass changing it. When satisfied with the
voltage value, press the DONE function key to continue.
Pulse train has two variable parameters, frequency and pulse count.
Since the calibrator can only store one variable parameter per test,
one of these must be set to a fixed value for all test points, while the
other is changed. A second prompt allows the fixed parameter to be
selected, and a value to be entered for it. In the sample below,
frequency is currently selected as the fixed parameter with a value of
2.0 Hz.
Press the FREQ function key or the COUNTS function key to select
the fixed parameter. The upper display will change to reflect the
current value for that parameter. Enter the new parameter value
using the numeric keys followed by the ENTER key, or if satisfied
with the current parameter selection and value press the DONE
function key to bypass changing it. When satisfied with the
parameter selection and value, press the DONE function key to
continue.
8.2.2 Data Collection
The test for each point consists of setting the output value, waiting
for the input to settle, and saving the data. This process is repeated
until the desired number of test points are recorded. For ease of
