• Setting the Number of Stages of Moving Average: TAP
Select the number of stages from 2, 4, 8, 16, 32, 64, and 128.
For details on other filters, see appendix 6.
Setting Value/Div
Like V/div, Value/Div is set using 1-2-5 steps. The selectable range is 10.00E–21
[Value/Div] to 500.0E+18 [Value/Div] with 123 settings.
Turn the V/DIV knob to set the Value/Div value. You can also set Value/Div by pressing
the Value/Div soft key and turning the jog shuttle.
Automatically Selecting the Optimum Value/Div Setting
When you press the Optimize Value/Div soft key, the optimum range is automatically
selected from the 123 Value/Div settings, and the waveform is displayed using the
selected setting.
Zooming in on the Waveform
• Zooming in or out Vertically by Setting the Magnification
For details, see section 5.8, “Zooming Vertically by Setting the Zoom Rate” and
“Notes Concerning Display” in section 15.1.
• Zooming/Expanding Vertically According to the Upper and Lower Limits of the
Display Range
For details, see section 5.9, “Zooming Vertically According to the Upper and Lower
Limits of the Display Range” and “Notes Concerning Display” in section 15.1.
Setting the Unit
Unit can be set arbitrarily using up to four characters. The specified characters are
applied to the scale values.
Notes When Using Filters
The following limitations exist depending on the acquisition mode setting.
• When the Acquisition Mode Is Set to a Mode Other Than Envelope
The digital filter frequency is set in terms of a percentage of the sampling frequency.
For example, if the sampling frequency is 100 kHz and you set the cutoff frequency to
10%, the cutoff frequency is set to 10 kHz. If the sampling frequency exceeds 100
kHz, the sampling frequency of DSP channels is decimated to 100 kHz. Therefore, if
the sampling frequency exceeds 100 kHz, the specified frequency is a percentage of
100 kHz regardless of the actual sampling frequency.
• When the Acquisition Mode Is Set to Envelope
The sampling frequency of DSP channels is fixed to 100 kHz. The digital filter
frequency is set in terms of a percentage of 100 kHz.
Note
For other notes concerning DSP channels, see section 15.1.
