In the bit editor, notice that the ignored bit of the bit- data is not displayed, however the hex value still shows all three bytes. This is because bits 1 through 7 are part of the first byte, which is shown as ASCII character x in the SCPI command line. The view from the hex editor program confirms that the downloaded three bytes of data remains unchanged. To view a downloaded bit file with an external hex editor program, FTP the file to your PC/UNIX workstation. For information on how to FTP a file, see “FTP Procedures” on page 303.

Even though the signal generator views the downloaded data on a bit basis, it groups the data into bytes, and when the designated number of bits is not a multiple of 8 bits, the last byte into one or
