Class Format memory management
Description Checks the current contents of the format buffer for errors; if no errors are found, it
reconfigures the signal generating hardware in accordance with the contents. It does not
redraw the previously displayed test image. In some cases this may distort the old image.
The FMTU? query returns either a format memory location location or zero. If the signal
format currently being output by the signal generating hardware matches that originally
loaded (using the FMTL command) or read (using the FMTR command) from a format
memory location, then the matching format memory location location is returned.
Otherwise, if the format contents have been used to update the signal generating
hardware since either an FMTR or FMTL command has been issued, then FMTU? query
returns zero.
