b) Interpret the response of the query. The response is returned in the form of a
SCPI command. For example a response
:SOUR:POW 6
asks for a power of 6
dBm.
For a list of all possible responses see
3. Set the LO according to the required settings.
4. Repeat steps 2 and 3 until the value of step 2b is
:CALibration:HREQ:STOP
.
5.
:CALibration:xxx:RESult?
xxx
stands for
IQModulator
,
IQModulator:LOCal
or
LEVel
a) Query the result of the adjustment request with the SCPI com-
mand
:CALibration:xxx:RESult?
.
b) The query returns either 0 or 1 signifying pass or fail.
The instrument is calibrated and can be further used.
How the described process may take place is shown in
patible R&S signal generator the whole process will be completed automatically.
