File Transfer Function

This section describes how to use the file transfer function, showing you a sample program.

The file transfer function uses the external controller to transfer files between the selected

storage device of this instrument (RAM disk, flash disk or diskette) and an external storage

device (such as hard disk). This function allows you to:

• Directly access data you want to use on the external controller.

For example, you can transfer the files saved on the 4294A storage deveice, such as

graphic files or data array (ASCII format) files, to the external controller. Then, you

can output the graphic file transferred from a printer connected to the external

controller, or manage the data array (ASCII format) trasferred using a software running

on the external controller.

• Use external storage devices, which have larger capacity compared to RAM disk, flash

disk or a diskette.

For example, if there are a great number of measurement conditions which require

calibration, the amount of the setting data becomes extremely large, including

calibration data. In this case, it is impractical to store all of these settings on the RAM

disk, flash disk or a single diskette at a time. However, you can realize this

functionality by transferring them to the external controller and then storing them on an

external storage device.

• Perform remote measurement using the external controller with a few GPIB commands

for basic measurement. You do not have to memorize further details (such as GPIB

commands used for detailed settings).

1. Preparation

Use the keys on the front panel to establish the setting required for your

measurement. Store it on the storage device of the 4294A, then transfer the file to

the external controller, and store it on an external storage device. Repeat this

procedure for all of the settings required for your measurement.

2. Measurement

Choose a necessary setting file from those stored and transfer it to the 4294A using

the external controller. Then, recall the file to set the 4294A for the measurement

and perform the measurement using the GPIB commands.

The storage device of the 4294A allows you to handle files listed below in the DOS format.

Both binary files and ASCII files can be transferred.

• Binary files

o Instrument settings and internal data array (STATE)

o Internal data arrays (DATA ONLY binary)

o Graphic images (GRAPHICS)

•ASCII files

o Internal data arrays (DATA ONLY ascii)

o Instrument BASIC programs
