Note that unless stated otherwise, a query always returns a numeric value in the SI
derived unit (Hz in case of a frequency, not in kHz, MHz or GHz) and with several
decimal places (usually six).
Commands like
SENSe:FREQuency:CENTer
work a setting and a query. Other
commands do not work both ways.
*IDN
, for example, is only allowed as a query
(setting anything is not possible).
*RST
, for example, is only allowed as a setting (a
query is not possible). Information about how you can use command is included in
the command description.
10. Send a succession of commands to measure the spectrum around the center fre-
quency of 100
MHz.
a)
initiate:continuous off
This command selects single sweep mode, recommended for remote measure-
ments.
b)
initiate:immediate;*wai
You can write two commands into one command line, but have to separate
them with a semicolon (;). The first command (
INITiate:IMMediate
) ini-
tiates the measurement. The second command (
*wai
) instructs the program to
wait until the preceding command (
INITiate:IMMediate
) has been execu-
ted before any subsequent commands are sent. This synchronization to the
end of the measurement is important, because it makes sure that the measure-
ment is done before taking another action.
11. When the measurement is done, you can query the measurement results (trace
data).
Send the query
trace:data? trace1
to do so.
