Fast Data Transfer Commands - HP 8753E Programming And Command Reference Manual

OUTPMSTA insures that the statistics have been calculated for the
n
current trace before transmitting data. If the statistics are not
activated, it will activate the statistics long enough to update the
current values before deactivating the statistics.
OUTPMWID insures that a bandwidth search has been executed for
n
the current trace before transmitting data. If the bandwidth-search
function is not activated, it will activate the bandwidth-search
function long enough to update the current values before switching
OFF the bandwidth-search functions.
The HP 87533 has four distinct fast data transfer commands. These
commands circumvent the internal "byte handler" routine and output
trace dumps as block data. In other words, the analyzer outputs the
entire array without allowing any process swapping to occur. FORM4,
ASCII data transfer times are not affected by these routines. However,
there are speed improvements with binary data formats. The following
is a description of the four fast data transfer commands:
OUTPDATF outputs the error corrected data from the active channel
n
in the current output format. This data may be input to the analyzer
using the INPUDATA command.
OUTPFORF outputs the formatted display trace array from the active
n
channel in the current output format. Only the first number in each
of the OUTPFORM data pairs is actually transferred for the display
formats L 0 G M H G , F'
and I
value for these display formats, the INPUFORM command may not be
used to re-input the data back into the analyzer. The second value
may not be significant in some display formats (see Table l-4), thus
reducing the number of bytes transferred.
OUTPMEMF outputs the memory trace from the active channel. The
n
data is in real/imaginary pairs, and, as such, may be input back into
the memory trace using INPUDATA or INPUFORM followed by the
DATI command.
n
may be input back into the memory trace using the INPURAW<I>
command.
