INITiate Subsystem
The INITiate subsystem is used to control the init measurement function in the selected measurement
window. In receiver mode, a distinction is made between single measurement (INITiate1) and scan
(INITiate2). In signal analyzer mode, a distinction is made between INITiate1 (screen A) and INITiate2
(screen B) in split screen representation.

INITiate<1|2>:CONTinuous ON | OFF
This command determines whether the trigger system is continuously initiated (continuous) or
performs single measurements (single).
Setting "INITiate:CONTinuous ON" corresponds to function SCAN/SWEEP CONTinuous, i.e. the
scan/sweep of the receiver/analyzer is cyclically repeated. The setting "INITiate:CONTinuous
OFF" corresponds to function SCAN/SWEEP SINGLE..
Example: "INIT2:CONT OFF" 'Switches the sequence in screen B to single
'scan/sweep.
"INIT2:CONT ON" 'Switches the sequence to continuous scan/sweep.
Characteristics: *RST value: ON
SCPI: conforming
Mode: all
INITiate<1|2>:CONMeas
When a scan is automatically interrupted by a transducer interrupt point, this command continues the
measurement at the current receiver frequency. A selectively interrupted scan (INTERRUPT) is
continued by a new INITiate2:IMMediate command.
This command continues a stopped measurement at the current position in single sweep mode. The
function is useful especially for trace functions MAXHold, MINHold and AVERage if the previous
results are not to be cleared with Sweep Count > 0 or Average Count > 0 on restarting the
measurement (INIT:IMMediate resets the previous results on restarting the measurement).
The single-sweep mode is automatically switched on. Synchronization to the end of the indicated
number of measurements can then be performed with the command *OPC, *OPC? or *WAI. In the
continuous-sweep mode, synchronization to the sweep end is not possible since the overall
measurement "never" ends.
Example: "INIT:CONT OFF" 'Switches to single-sweep mode.
"DISP:WIND:TRAC:MODE AVER 'Switches on trace averaging.
"SWE:COUN 20" Setting the sweep counter to 20 sweeps.
"INIT;*WAI" 'Starts the measurement and waits for the
'end of the 20 sweeps.
"INIT:CONM;*WAI" 'Continues the measurement (next 20
'sequences) and waits for the end.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A
This command is an event and therefore has no *RST value and no query.
