DATA and SETup Commands

SYSTem:DATA

SYSTem:DATA
Command :SYSTem:DATA <block data>
The SYSTem:DATA command transmits the acquisition memory data from
the controller to the HP 16554A/HP 16555A/HP 16555D logic analyzers.
The block data consists of a variable number of bytes containing information
captured by the acquisition chips. Since no parameter checking is
performed, out-of-range values could cause instrument lockup; therefore,
care should be taken when transferring the data string into the HP 16554A/
HP 16555A/HP 16555D.

the total length of the block is 14522 bytes, the block length specifier would

For the DATA instruction, there is only one
of a data preamble followed by the acquisition data. This section has a
variable number of bytes depending on configuration and amount of acquired
data.

OUTPUT XXX;":SYSTEM:DATA" <block data>
Do not load UNPacked data into the instrument; it may cause the HP 16500 to
lock up. If this happens, cycle power. Only data saved in PACKed mode can be
reloaded back into a logic analyzer.
