DME1600
Message Overview
SCPI command syntax (continued)
Queries
You can query the settings and status of the DME1600.
To make a query, append a question mark to the end of the program header section.
Terminating character strings
The command strings sent to the DME1600 are terminated with <new line> characters. The
IEEE-488 EOI (end or identify) message is treated the same as <new line> characters, so
you can use the EOI message instead of <new line> characters as the end of a command
string. You can also use <carriage return> + <new line>.
When a command string is terminated, the current SCPI command path is reset to the root
level.
Parameters
The SCPI language defines various data formats for use in messages.

Numeric parameters
Commands that require numeric parameters can contain all widely used decimal expres-
sions, including optional signs, decimal points, and scientific notation. They can also contain
special numeric parameter values, such as MINimum, MAXimum, and DEFault. You can also
attach an engineering unit suffix (such as M, K, or u) to a numerical parameter when you send
it. When the DME1600 can only accept specific values, it automatically rounds the input
parameter values. The following is a command that contains a numeric parameter.
VOLTage:DC:RANGe {<range>|MINimum|MAXimum}
 Discrete parameters
Discrete parameters are used for settings that have a limited number of values (such as BUS,
IMMediate, and EXTernal). Like command keywords, discrete parameters can be transmitted
in short form or long form, and they are not case-sensitive.
Query responses are always given in all caps in short form. The following is a command that
contains a discrete parameter.
TRIGger:SOURce {BUS|IMMediate|EXTernal}
 Boolean parameters
Boolean parameters can be either true or false. The DME1600 recognizes parameter values
of “OFF” and “0” as indicating false Boolean values. The DME1600 recognizes parameter
values of “ON” and “1” as indicating true Boolean values. The DME1600 only responds to
Boolean parameter queries with “0” or “1.” The following is a command that contains a Bool-
ean parameter.
INPut:IMPedance:AUTO {OFF|ON}
If you want to send two queries on separate lines, send the second query after you have
received the response to the first one. If you send query commands on two lines at the same
time, you may receive an incomplete response.
