Note that special values for numeric parameters such as MINimum and MAXimum are also accepted.
Instead of selecting a specific value for the voltage parameter, you can substitute MIN to set the
voltage to its minimum allowable value, or MAX to set it to its maximum allowable value.
You can also optionally include the following engineering unit suffixes with numeric parameters:
Parameter Default Unit
Voltage V
Current A
Wattage W
Apparent Power VA
Reactive Power VAR
Degrees DEG
Frequency HZ
You may also put the following prefixes before a unit of measure:
Prefix Meaning Number
U micro 1/1,000,000
M milli 1/1,000
K kilo 1,000
As with other SCPI keywords, both units and prefixes are case-insensitive. Thus, you could indicate
millivolts as mv, mV, Mv, or MV.
Discrete Parameters
Discrete parameters specify settings that have a limited number of values (like IMMediate, EXTernal,
or BUS). Like command keywords, they may have short and long forms. You can mix upper- and lower-
case letters. Query responses always return the short form in upper-case letters. The following
command requires a discrete parameter:
DISPlay:VIEW METER_VI|METER_VP|METER VIP
Boolean Parameters
Boolean parameters represent a single binary condition that is either true (1 or ON) or false (0 or OFF).
A boolean query always returns 0 or 1. The following command requires a boolean parameter:
DISPlay ON|1|OFF|0
ASCII String Parameters
String parameters can contain virtually any ASCII characters. A string must begin and end with
matching single (') or double (") quotation marks. To include the quote delimiter as part of the string,
enter it twice without any characters in between. The following command uses a string parameter:
DISPlay:TEXT "Test in progress . . ."
