4.3 Loading Data

101

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.

Chapter 4 Saving/Loading Data & Managing Files

You can save settings data or waveform data on storage media. Data will be saved in the folder indi-

cated by the cursor. By using the A/B cursor pair, waveform data can be saved partially.

4.4.1 Saving

Procedure

To open the screen: Right-click and select [FILE] File screen To change the media: (p.84)

Select storage media for saving.

See: "To change the media"(p.84)

Move the flashing cursor into the folder to save.

Set the data to save.

Select [Save] and then select [Save Type].

Set the file name.

Move the flashing cursor to the [Save Name] item.

Enter the save name.

See: "7.1.3 Alphanumeric Input" (p.141)

Specify the action if a file with the same name exists in the

target folder.

Move the flashing cursor to the [Same Name] item.

Auto If no files with the same name exist, saves the file with the des-

ignated name. Otherwise, a 4-digit number is automatically

added to the beginning of the file name (default setting).

If the first character of the file name is a numeral, the

added number will continue sequentially from that number.

Serial

Unconditionally, a 4-digit number is automatically added to

the beginning of the file name. If a file with the same name

exists, saves the file, adding the 4-digit number that is in-

creased by 1.

Overwrite

Saves the file with the designated name.

Error

If a file with the same name exists, an error message will be

displayed.

• Data saved with the "Text"

option is only for loading to a

PC and cannot be loaded

back into the instrument. To

reload the data later into the

instrument, use the "Binary"

option.

• When [Memory (Int)] is

selected as storage media,

only settings data can be

saved.

• The waveform evaluation

area you have created can

be saved as a black-and-

white BMP file. Saved data

can be edited on a computer

and loaded back into the

instrument. Edit images in

black and white only.
