Averagemode - HP 1652B Getting Started Manual

Average Mode
In Average mode, the oscilloscope averages the data points on the
waveforms with previously acquired data. Averaging helps eliminate
random noise from your displayed waveforms. When the Average field
is selected from the
Display mode pop-up, an integer field appears to
-
the
right of the AVG# field. When this Average integer field is
selected, an integer selection list pop-up appears, listing all possible
average selections.

Average Integer Entry Pop-up
The number of averages can be changed by turning the knob to
position the cursor over the integer you want and pressing
the
SELECT key.
As an example, assume the Average integer field is set to
16.
If the
Run mode is set to Repetitive, the oscilloscope will immediately start
acquiring waveform
data and average them together. When the initial
16
waveforms have been acquired, the oscilloscope will momentarily
display the advisory "Number of averages have been met". Once the
initial
16
waveforms have been acquired, the oscilloscope will only
average the last
16
waveforms acquired; all other data will be discarded.
If the Run mode is set to Single, an acquisition is not made until the
Run field has been selected. If Average # is set to
16,
as in the
previous example, the message "Number of averages have been met"
would not be displayed until Run has been selected
16
times.
