4.2 Setting Measurement Configuration (Status Settings Screen)
86
Make basic settings for measurement such as timebase and recording length on
the Status Settings screen. These settings can also be made on the Waveform
screen (p. 114).
Choices of setting items are function-dependent.
Refer to the
Analysis and Communication Supplement for FFT function setting
details.
This applies to the Memory function and the Real-time saving function only.
Select the analog and logic channels to use.
When an input module is installed, the maximum number of usable channels
(“Usable Channels” value) is automatically updated. The number of usable chan-
nels consists of the total of all analog and all logic input channels.
Refer to "Chapter 9 Measuring with Real-Time Saving" (p. 235) for settings
related to real-time saving.
The following apply to the Memory function only.
4.2 Setting Measurement Configuration
(Status Settings Screen)
4.2.1 Selecting Channels to Use
To set the recording length as long as possible
Maximum recording length is available when the fewest necessary channels are
enabled for use. Minimizing the number of channels in use by turning off those
that are not needed allows memory to be reallocated to those channels being
used.
To perform simultaneous measurements with different sampling rates
By setting different sampling rates to “Timebase 1” and “Timebase 2”, recording
with either sampling rate can be selected for each channel.
See "Setting Timebase 1 and 2: Using input modules other than the Model 8958 16-Ch
Scanner Unit" (p. 95)
Using the Model 8958 16-Ch Scanner Unit
• Recording with the Model 8958 16-Ch Scanner Unit is not available with the
Real-Time Saving function.
• When only the Model 8958 is installed in the instrument, set the used chan-
nels to Timebase 1 .
See "Setting Channels to Use: When using only the Model 8958 16-Ch Scanner Unit" (p.
89)
• When another module is also installed, Timebase 2 can only be set for the
Model 8958. Timebase 2 cannot be set for the other input module(s).
See "Setting Timebase 1 and 2: When using the Model 8958 16-Ch Scanner Unit
together with other input modules" (p. 96)
When measuring using external sampling
Only Timebase 1 can be set for such channels.
See "14.2.3 External Sampling (EXT.SMPL)" (p. 382)
