10 Interfaces (IEEE option L45-O1)
With exception of the IEEE interface all interfaces could also be used for data logging (see 11,
‘Logging of values to drives, printer and interfaces’). To remote control the LMG please
reserve first the wished interface for this job (see 4.4.2.1, ‘Interfaces for remote control’).
This chapter includes all commands and a short general syntax description. A much more
detailed syntax description with a lot of examples and further programming explanations can be
found in our Programmer’s Guide on the CD which is included in the printed version of this
manual. If this is missing or you have just a PDF version of this manual you can request the
Programmer’s Guide by email from ‘sales@zes.com’.
10.1 Short syntax description
There are two implemented languages: SCPI and SHORT. When switching on the instrument
SCPI is selected. To change to SHORT you have to send:
SYST:LANG SHORT
For further differences between SCPI and SHORT command set see also 10.2.4, ‘:FETCh and
:READ commands’
The general syntax for both command sets is identical. The most important syntax rules are:
•
A message to the instrument has to be terminated with an EOS character.
•
brackets [..] are showing optional part of commands. There is no need to send them to the
device, but you can do it, if you need this function. The brackets are just informative and
should not be sent.
•
The number of the measuring channel (further on called ‘suffix’) follows directly (without
any space) after the identifier. If you don’t specify one, ‘1’ is assumed.
•
If you request a value you have to add a ‘?’ directly behind the suffix (or the identifier, if no
suffix is specified), without any space.
•
All parameters following the commands have to be separated from the command with at
least one space character.
•
The group number is usually an optional parameter in the format [,<NRi>]. If you don’t
specify it, group A (=0) is assumed as default value.
•
‘/qonly/’ indicates, that this is a value which can only be demanded, but not set. Do not send
the ‘/qonly/’ string to the device, it is just written in this manual to explain the command.
For example you can’t send a measuring value.
