Responses to Queries
Unless otherwise expressly specified, a query is defined for each command. The query is created by
appending a question mark to the associated command. Some of the SCPI rules for query responses
are stricter than those of the IEEE 488.2 standard:
1. The required value is sent without header.
Example
:
SENSe:AVERage:TCONTrol?
Response:
MOV
2. Maximum and minimum values as well as all other quantities queried by a special text parameter
are returned as numeric values.
Example
:
SENSe:POWer:TSLot:COUNt? MAXimum
Response:
26
3. Numeric values are output without a unit. Physical quantities refer to the basic units or to the units
set with the UNIT command.
Example
:
SENSe3:FREQuency?
Response:
1.000000E06
(for 1 MHz)
4. Boolean values are returned as 0 (for
OFF
) and 1 (for
ON
).
Example
:
SYSTem:BEEPer:STATe?
Response
: 1
5. Character data is returned in short form
(
Æ

).
Example
:
UNIT2:POWer?
Response:
DBM
