4.2 Setting Measurement Configuration (Status Settings Screen)

Chapter 4 Measurement Configuration Settings

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. 108).

Choices of setting items are function-dependent.

Refer to the Analysis 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. 225) for settings

related to real-time saving.

The following apply to the Memory function only.

(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. 93)

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. 88)

• 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. 94)

When measuring using external sampling

Only Timebase 1 can be set for such channels.

See "14.2.3 External Sampling (EXT.SMPL)" (⇒ p. 394)
