Creating and Downloading User–Data Files

User File Data (Bit/Binary) Downloads (E4438C and E8267D)

Modifying a Bit File with a Hex Editor

1. FTP the file to your PC/UNIX.

For information on using FTP, see FTP Procedures. Ensure that you use binary file transfers

during FTP operations.

2. Modify the file using a hex editor program.

If you need to decrease or increase the number of bits of interest, change the file header hex

value.

3. FTP the file to the signal generator’s BIT memory catalog (directory).

FTP Procedures

CAUTION Avoid using the *OPC? or *WAI commands to verify that the FTP process has been

completed. These commands can potentially hang up due to the processing of other

SCPI parser operations. Refer to the SCPI Command Reference.

NOTE If you are remotely FTPing files and need to verify the completion of the FTP process, then

query the instrument by using SCPI commands such as: ':MEM:DATA:', ':MEM:CAT', '*STB?',

'FREQ?', '*IDN?', 'OUTP:STAT?'. Refer to the SCPI Command Reference.

There are three ways to FTP a file:

• use Microsoft’s ® Internet Explorer FTP feature

• use the signal generator’s internal web server (ESG firmware ≥ C.03.76)

80 Byte File From Signal Generator

02 80 hex = 640 bits designated as bits of interest

02 bd hex = 701 bits designated as bits of interest

Added bytes
