2.6REMOTE OPERATION
Fig. 2-56  Remote Mode
The Test Set may be operated remotely via GPIB interface standards.  The command
syntax and style is compliant with SCPI (Standard Commands for Programmable
Instruments).  Several SCPI features have been implemented in the Test Set to
facilitate system integration. These features include the extended status reporting
structure, the error numbering scheme, the command mnemonic derivation rules (i.e.
long and short form) and many of the frequently used commands.
Some of the features included in the Test Set are not defined by the SCPI standard;
but, the Test Set does meet the basic form and function to be compliant with SCPI
requirements.
GPIB Status: 
Each box represents the 8 bits of the GPIB STATUS byte. The boxes have the bit
number followed by the description of the bit. If there is a change in the status byte
data, the corresponding box will turn red in color.  If the box is then pressed (clicked
with a mouse)  a message box will appear with the data for this event.
