Overview

The time domain function provides the following functions:

• Transforming measurement data to data in the time domain (Transformation Function)

• Deleting unnecessary measurement data in the time domain (Gating Function)

Transforming Measurement Data to Time Domain

By using the Transformation Function, you can convert the results measured in the frequency domain to data in the time domain and analyze it.

On/Off

To turn on or off the transformation function, use the following command:

:CALC{1-36}:TRAN:TIME:STAT

Selecting Transformation Type

To select the transformation type (band pass/low pass), use the following command:

:CALC{1-36}:TRAN:TIME

To select the stimulus type (impulse/step) when the transformation type is low pass, use the following command:

:CALC{1-36}:TRAN:TIME:STIM

When the transformation type is low pass, you need to execute the following command because each measurement point must be a multiple of the start frequency.

:CALC{1-36}:TRAN:TIME:LPFR

Setting Window Shape

To set the window shape, use one of the following items.

The above three items are dependent on each other. When the value of one of them is changed, the values of the other two are automatically changed to corresponding values.

Unlike manual operation, you cannot set the window shape by selecting the window type (maximum/normal/minimum). However, you can set the same shape as each window type by setting β  as follows:

Setting Display Range

To set the display range after time domain transformation, use the following commands:

Deleting unnecessary measurement data in the time domain

You can use the Gating Function to delete unnecessary time domain data.

On/Off

To turn on or off the gating function, use the following command:

:CALC{1-36}:FILT:TIME:STAT

Selecting Gate Type

To select the gate type, use the following command:

:CALC{1-36}:FILT:TIME

Setting Gate Shape

To select the gate shape, use the following command:

:CALC{1-36}:FILT:TIME:SHAP

Setting Gate Range

To set the gate range, use the following commands:
