Video Test Generator User Guide 323
Class System Level
Description Changes the firmware in the generator’s flash EPROM via the GPIB port. This is
accomplished by sending an IEEE 488.2 standard arbitrary block program data to the
generator. The generator temporarily places the block in picture memory and, if received
intact, eventually transfers the binary image to flash memory by internally executing the
VTOF function. Note that one does not have to send VTOF after a FLSH transfer.
FLSH initiates the data transfer. An arbitrary_block_program_data argument containing
either 512K or 2M bytes of binary data should follow this command per standard
IEEE-448.2 section 7.7.6 GPIB data transfer methods.
Command syntax FLSH arbitrary_block_program_data
arbitrary_block_program_data
IEEE-488.2 arbitrary block program data per standard IEEE-448.2 section 7.7.6 GPIB
data transfer method. The maximum number of bytes sent depends on the generator:
801requires a maximum of 524288 bytes, while 802 requires a maximum of 2097152
bytes.
