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.
