Current Frequency:1 kHz when in internal trigger state
• When the *WAI command was not used
(Send)
:FREQuency 120;:MEASure?
In this case, it is not certain which frequency measurement value will be sent in
response to the :MEASure? query.
• When the
*
WAI command was used
(Send)
:FREQuency 120; * WAI;:MEASure?
In this case, the 120 Hz frequency measurement value is sent in response to
the :MEASure? query.
Note
Unique commands other than the ":MEASure?" query use sequential commands.
Therefore, the
*
WAI command is only effective for the ":MEASure?" query.
