Command Syntax
The commands are partially compatible with IEEE488.2 (1992) and SCPI
(1994) standard. Commands are NON-case sensitive.
1: Command Header
2: Single space
Example command conf:volt:dc _1
1 2 3
3: Parameter
Boolean
Boolean logic: 0 or 1. Used for On (1) or
Off (0) command.
Parameter example
NR1
Integer: 0, 1, 2, 3.....
NR2
Decimal number: 0.0, 0.1, 0.2,....
NR3
Floating point number: 4.5e-1, 8.5e+1,...
min, max
GDM-8200 series automatically translates
to Minimum (min) or Maximum (max)
value available.
GDM-8200 series automatically translates the command
parameter into the closest available value.
Automatic
parameter range
selection
Example 1
conf:volt:dc_1 (Sets the measurement
item to DC Voltage and the range to 1V).
GDM-8200 series selects the 1V range.
Example 2
conf:volt:dc_2 (Sets the measurement
item to DC Voltage and the range to 2V).
There is no 2V range so GDM-8200
series selects the closest range, 10V.
Message
Terminator
Marks the end of a command line. The following
messages are in accordance with IEEE488.2 standard.
LF
Line feed code (for USB, RS232C, GPIB
connection)
LF^END
Line feed code (hexadecimal 0A) with
END message (only for GPIB
connection)
<dab>^END
Last data byte with END message (only
for GPIB connection)
Message Separator ; (semicolon)
Command separator.

Command Set
•
Commands are non -case sensitive.
•
Underline means a single space (dc_1
→
DC 1V).
•
When the parameter does not match the real value, the closest possible
option is automatically selected (dc_2 [DC 2V range]
→ DC 10V)
