3.3.17 INITiate:CONTinuous[:ALL][?] – Start Sweeping
INITiate:CONTinuous[:ALL] {ON|OFF} enables sweeping so that sweeping will continue until this
command, *RST, SYSTem:PRESet, FREQ:MODE or POW:MODE is used to turn it off again.
Turning INIT:CONT OFF will allow the currently running sweep to terminate normally. To stop the cur-
rent sweep immediately, use ABORt or change the MODE. Note that if INIT:CONT is left ON after
ABORt, the sweep will restart immediately.
Executing *OPC? or *WAI with INITiate:CONTinuous ON will cause the unit to appear to hang. It will
continue to sweep, but any commands after *OPC? or *WAI will be ignored. See SDC.
The query form, INITiate:CONTinuous[:ALL]? returns 0 if continuous sweeping is OFF and 1 if it is
ON.
If TRIGger:SOURce is not IMMediate, each sweep will wait for a trigger.
If SWEep:COUNt is N, each trigger will result in N sweeps. (Note: Triggers which happen while a
sweep is in progress are ignored or result in errors.) If INIT:CONT OFF is used, the total number of
sweeps will be a multiple of N.
FREQ:MODE must be SWEep for the unit to begin sweeping frequency or POW:MODE must be
SWEep to begin sweeping power.

3.3.18 INITiate[:IMMediate][:ALL] – Start a Single Sweep
INITiate starts a sweep.
If TRIGger:SOURce is IMMediate, the sweep begins when this command is issued. Otherwise, it
waits for a trigger.
If SWEep:COUNt is N, each trigger or INIT will result in N sweeps. (Note: Triggers which happen
while a sweep is in progress are ignored or result in errors.)
FREQ:MODE or POWer:MODE must be SWEep or an error will be generated.
Sweep parameters, such as the FREQ:STARt and FREQ:STOP, are sampled at INIT time. If
INIT:CONTinuous ON, each time the sweep re-starts, the parameters are re-sampled. An ABORt
forces a continuous sweep to re-INIT, if you don't want to wait for the sweep to complete normally.
INITiate is an event; there is no query form.
