6 53220A/53230A Math, Graphing, and Data Logging
There are 1,000 readings in each decimation group in Figure 6-10
(100,000 readings/100 points displayed). The number of readings in each
group changes if Show All is pressed and readings continue to be taken.
When a marker is moved to a decimation point, the number of the first reading
in the corresponding group is displayed. This number should be noted if it is
necessary to view individual readings within a group.
Viewing Readings Within a Decimation Group Decimated reading values that
are grouped and represented by a single decimation point can be viewed indi-
vidually using markers and the trend chart’s Pan control.
1 Select a marker and using the knob, move the marker to the decimation
point with the reading level of interest. The reading number corresponding
to the marker position is the first reading in the group. This may not be the
maximum or minimum value within the group.
2 Select ‘Pan’ and using the [Shift]ed numeric keys, enter the number of the
first reading. The reading indices show a span of 100 readings, beginning
with the first reading in the group.
3 Select Marker1 or Marker2 and using the arrow keys, highlight the rightmost
(1's) place in the position window. Rotate the knob to move the marker one
reading at at time. The reading value and number are shown as the marker
is advanced.
For decimation groups with more than 100 readings, select ‘Pan’ and enter the
next reading number after the upper reading index (Figure 6-8) to view the
next 100 readings.
Data Logging
The data logging feature of the 53220A/53230A counter allows you to log and
analyze up to 1,000,000 readings. Data logging is enabled and configured from
the front panel only, and is available with all counter measurements except
continuous totalizing.
