Instructs
the 9400A to transmit
the
waveform descriptor, data and time(s)
Channel 2, including all invisible data
values
on the left-hand
side
of the
screen. The address -32000 is
usually
out
of range,
but
the
9400A
automatically
adapts
to the
closest
legal value. This complete data record
is restored in memory C with the command
WRITE MC.*,,,-32000.

*
transfer
the waveform
descriptor
from the host computer
to the
indicated
memory
location
of the 9400A.
This command
must be
followed by the descriptor block(s). The 9400A checks the limits
each parameter transmitted.
If any value is out of range, or the
number of values transmitted
is incorrect,
the entire descriptor
block is considered invalid and is discarded.

<Parameter list> = <intval> , <# values> , <addr> , <sweep #>
transfer
data values
from the host
computer
to the indicated
memory location of the 9400A. This command must be followed by the
data value block(s).
See the READ command for an explanation
<Parameter list>.
or
WRITE (WT) , < MEMORY C.TIME (MC.TI)
*
< MEMORY-D.TIME (MD.TI)
*
transfer trigger time(s) from the host computer to the indicated
memory location of the 9400A. This command must be followed by the
trigger
time
block.
If the number
of values
transmitted
is
incorrect, the entire block is discarded.
When transferring WRITE DATA without specifying the number of data
values, the nominal number + I data values must be sent to the 9400A
(25000 + 1 data values for example). This additional value may
needed for the generation of the last displayed point at the right
hand side of the screen.
