Responses to Queries
A query is defined for each setting command unless explicitly specified otherwise. It is formed by adding
a question mark to the associated setting command. According to SCPI, the responses to queries are
partly subject to stricter rules than in standard IEEE 488.2.
1 The requested parameter is transmitted without header.
Example:
SOURce:EXTernal:COUPling?
Response:
AC
2. Maximum values, minimum values and all further quantities, which are requested via a special text
parameter are returned as numerical values.
Example:
FREQuency? MAX
Response:
10E3
3. Numerical values are output without a unit. Physical quantities are referred to the basic units or to the
units set using the Unit command.
Example:
FREQuency?
Response:
1E6
for 1 MHz
4. Truth values <Boolean values> are returned as 0 (for OFF) and 1 (for ON).
Example:
OUTPut:STATe?
Response:
1
5. Text (character data) is returned in a short form (see also Section 3.5.5).
Example:
SOURce:FM:SOURce?
Response:
INT1
