4.3 Loading Data

Chapter 4 Saving/Loading Data & Managing Files

Data saved on media or in the internal memory of the instrument can be reloaded.

Before attempting to load data, make sure that the storage media is inserted and the loading target

is correctly specified.

Only settings and measurement data saved in binary format can be loaded into the instrument.

Refer to "7.10 Register the Waveform in the U8793 Arbitrary Waveform Generator Unit" (p.184), or the

instruction manual of Models U8793, MR8790, and MR8791 regarding the detailed settings for loading (regis-

tration) of pulse pattern data, arbitrary waveform data, program data.

When loading settings data, you can select whether to load communication settings such as the IP

address of the LAN.

No: Does not load the communi-

cation settings.

(Default setting)

Yes: Loads the communication set-

tings.

Loading Example (Loading a Memory Division File)

Right-click to display the list menu, and then click [FILE].

Double-click the SEQ file in the folder created in step 8 of "Saving a Memory Division

Waveform File", and then click [Exec] to load the waveform data on the instrument so that

it becomes the same as when each memory block was saved.

Double-click a MEM file in the folder created in step 8 of "Saving a Memory Division Waveform

File", and then click [Exec] to load only the waveform data of that block to the instrument.

Double-click this,

and then click

[Exec] on the right

of the screen.

When loading from a source other than the internal memory

Insert the storage media before making the media selection.

Other limitations

• Data saved with Memory HiCorders other than the MR8740/MR8741,

MR8847s and MR8827 cannot be loaded.

• When loading waveform data, the settings for the instrument are the same set-

tings as when the data is saved. To reset to the instrument settings, carry out

[Clear Wave Data] (p.374) or start the measurement.

Chapter 4 Saving/Loading Data & Managing Files

When the following index files are loaded, waveform data can be loaded as a batch. With the following

settings, index files are created along with waveform files.

Files with the following two extensions can be loaded:

You can load data for generated modules.

Data loading is performed on Signal generator sheet of Channel screen (

CHAN key) or FILE screen (FILE key).

For details, see the instruction manual of Models U8793, MR8790, and MR8791.

Batch load of waveform data

Extension Explanation

IDX

Divided files are loaded together.

(To create index files: Use [Division] at the [File Save] sheet of the System screen to set the dividing

size and then save. Note: If [Save type] is not [Wave Binary], index files are not created)

See: "4.2.2 Automatically Saving Waveforms" (p.88)

"4.2.3 Saving Data Selectively (SAVE)" (p.93)

SEQ

(When using the memory division function of the memory function)

Waveform data of all blocks is loaded together.

(To create index files: At the [Memory Div] sheet of the Status Screen, set [Memory Div] to [On].

At the [File Save] sheet of the System Screen, set [Save Type] to [ALL-Wave Bin].)

See: "11.1 Recording Settings" (p.243)

"4.2.3 Saving Data Selectively (SAVE)" (p.93)

Loading a waveform evaluation area (MR8741 only)

Extension Explanation

ARE

Loads waveform evaluation areas and settings data (files saved by selecting "Area settings"

when saving the data).

BMP

Loads waveform evaluation areas. (Files saved by selecting "Area image" when saving the

data can be edited on a computer and then loaded back into the instrument.)

Data Loading for Waveform Generation (Registration)

Extension Explanation

WFG,

TFG

The data for waveform generation is loaded in channels of a specified arbitrary waveform gener-

ator module. The waveform data loaded (registered) is output from Model U8793 Arbitrary Wave-

form Generator Unit.

Refer to"7.10 Register the Waveform in the U8793 Arbitrary Waveform Generator Unit" (p.184)

PLS

The data for pulse pattern generation is loaded in channels of a specified arbitrary wave gener-

ator module.

The pulse pattern waveform loaded (registered) is output from Model MR8791 Pulse Generator

Unit.

FGP

The waveform generation program file is loaded in channels of a specified arbitrary waveform

generator module.
