The instrument LCD provides SVGA resolution (800 × 600 ). The
waveform display area consists of 625 horizontal dots and 500 vertical
dots.
The waveform display area has 25 divisions horizontally and 20
divisions vertically, with each division composed of 25 dots horizontally
and vertically.
Each data frame (one division) represents 100 samples horizontally
and 100 to 50000 least significant bits (LSBs) vertically (depending on
the input module).
Each displayed data frame (one division) changes in accordance with
expansion and compression of the time and voltage axes.

Timebase and Sampling
For the memory function (Sampling point recording)
The sampling period is 1/100 of the timebase. When the timebase is
set to 100 ms/div, the sampling period is 1 ms. Changing the timebase
setting also changes the sampling period accordingly.
Sampling points
Sampling period
For the recorder function (Envelope recording)
In every one data point, which is 1/100 of the timebase, two values
are recorded: the maximum and minimum values obtained during the
specified sampling period.
With 10 ms/div of the timebase setting, one data point is 100 μs. When
the sampling period is set to 1 ms, one data point consists of 100
samples. The two values, the maximum and minimum values obtained
during 100 samples are recorded each data point, .

Recording Length Setting
Set the time length (the number of divisions) during which data are recorded for one data recording
event.
Each division of the recording length consists of 100 data points. The number of data during the
whole recording length is calculated from the following formula:
The specified recording length (number of divisions) × 100 + 1
Example: The number of data for the specified recording length of 50 divisions
50 divisions × 100 + 1 = 5001
Voltage axis and resolution
The resolution differs depending on input modules.
The following table shows the full scale resolution for all the modules.
The minimum resolution can be calculated from the screen full scale value and the full scale
resolution shown in the table below.
