Description Measuring with the Recorder Function
• When the following timebase values are selected, displayed waveforms are
compressed in the horizontal (time axis) direction as shown.
50 ms/div →
x1/2, 20 ms/div → x1/5, 10 ms/div → x1/10
• When the recording length [Shot] is to set [Cont] (Continuous), the timebase
must be set to at least 20 ms/div. Faster timebase settings are not available.
• When the Model 8958 16-Ch Scanner Unit is installed, the timebase can be
set between 50 ms/div and 1 h/div.
• If the sampling rate is set too fast, when the input waveform amplitude is
small, the difference between maximum and minimum values may become
quite large as a result of sudden impulses such as noise. To prevent such
phenomena, select a slower sampling rate or enable the input module’s low-
pass filter (⇒ p. 111).
See"Appendix 4.4 Recorder Function Values" (⇒ p. A51)
This applies to the Memory function only.
Different sampling rates can be set for Timebase 1 and Timebase 2. The follow-
ing channels can be set to Timebase 2.
• Channels on which you want to measure with a slower sampling rate than that
of Timebase 1 (⇒ p. 93).
• Channels on the Model 8958 16-Ch Scanner Unit when used together with
another input module (Timebase 2 is then set exclusively for the 8958) (
⇒ p. 94).
4.2.3 Setting Different Sampling Rates
Setting a slow sampling rate for Timebase 2 results in longer preparation time
prior to the start of storage.
