8.2.3.2 Structure of a Command Line
A command line may consist of one or several commands. It is terminated by one of the
following:
●
a <New Line>
●
a <New Line> with EOI
●
an EOI together with the last data byte
Several commands in a command line must be separated by a semicolon ";". If the next
command belongs to a different command system, the semicolon is followed by a colon.
Example:
MMEM:COPY "Test1","MeasurementXY";:HCOP:ITEM ALL
This command line contains two commands. The first command belongs to the MMEM
system, the second command belongs to the HCOP system.
If the successive commands belong to the same system, having one or several levels in
common, the command line can be abbreviated. To this end, the second command after
the semicolon starts with the level that lies below the common levels. The colon following
the semicolon must be omitted in this case.
Example:
HCOP:ITEM ALL; HCOP:IMM
This command line is represented in its full length and contains two commands separated
from each other by the semicolon. Both commands are part of the HCOP command sys-
tem, i.e. they have one level in common.
When abbreviating the command line, the second command begins with the level below
HCOP. The colon after the semicolon is omitted. The abbreviated form of the command
line reads as follows:
HCOP:ITEM ALL;IMM
However, a new command line always begins with the complete path.
Example:
HCOP:ITEM ALL
HCOP:IMM
8.2.3.3 Responses to Queries
A query is defined for each setting command unless explicitly specified otherwise. It is
formed by adding a question mark to the associated setting command. According to
SCPI, the responses to queries are partly subject to stricter rules than in standard IEEE
488.2.
●
The requested parameter is transmitted without a header.
Example:
HCOP:PAGE:ORI?
, Response:
LAND
●
Maximum values, minimum values and all other quantities that are requested via a
special text parameter are returned as numeric values.
