Switch System Reference Manual
Continuous initiation must be disabled in order to set the sample counter >1 (see
Reference c).
INITiate:CONTinuous, INITiate, and READ? — In order to initiate a single scan
cycle using INITiate or READ?, continuous initiation must be disabled. If you send
INIT or READ? with continuous initiation enabled, error -213 (Init ignored) will
occur.
You cannot use READ? or INITiate if sample count >1 AND there are readings
stored in the buffer by the TRAC command or by front panel data store operation
(error -225, out of memory). Either set the sample count to one or clear the buffer
(TRACe:CLEar).
A detailed example for 7751/7752/7753 memory pattern scanning is located in
