COMM_ORDER, CORD
Command/Query
The COMM_ORDER command controls the byte order of wave-
form data transfers. Waveform data may be sent with the most
significant byte (MSB) or the least significant byte (LSB) in
first position. The default mode is the MSB first.
COMM_ORDER applies equally to the waveform’s descriptor and
time blocks. In the descriptor some values are 16 bits long
("word"), 32 bits long ("long " or "float"), or 64 bits long ("dou-
ble"). In the time block all values are floating values, i.e. 32 bits
long. When "COMM_ORDER HI" is selected the most significant
byte is sent first. When "COMM_ORDER LO" is specified the
least significant byte is sent first.
The COMM_ORDER? query returns the byte transmission order
currently in use.
Note: This command can be executed in both local and remote
modes.
Comm ORDer <mode>
<mode> := {HI, LO}
Note: The initial mode, i.e. the mode after power on, is HI.
Comm ORDer?
Comm_ORDer <mode>
The order of transmission of waveform data depends on the data
type. Table 3 illustrates the different possibilities.
