(3) ? (question mark)
Appending “?” (question mark) to the end of a command creates a command
(query) that queries the device status.
(4) , (comma)
Delimits multiple parameters
(5) (space)
Divides the header from a parameter.
(6) ; (semi-colon)
Connects two commands to process them as a single command.
Example:
SCRSEL SYSCFG;DATEMODE DMY
(7) * (asterisk)
Indicates that the command is an *IEEE488.2 common command.
Example:
*IDN?
(8) " (double quotation mark), ' (quotation mark)
Appended at the beginning and the end of a character string when the character
string is specified as a parameter.
Example:

7.4.2 Setting parameters with unit specified
To specify the unit of parameter in a command, append a character string called a
“suffix code” at the end of a parameter. The suffix code may be omitted. If omit-
ted, setting is made in the predetermined response unit.
Example:
Setting the frequency to 1922 MHz (by a command from W-CDMA meas-
urement software)
TFREQ 1922MHZ /*with suffix code (set in MHz)*/
TFREQ 1922000000 /*without suffix code (set in Hz)*/
Table7-4-2-1 shows suffix codes available for the MT8820A:
