Arming the Triggering Cycle

■

INITiate:CONTinuous

■

INITiate[:IMMediate]

The Initiate commands enable the power meter to acquire measurement data at the next instrument 
trigger. In the absence of an instrument signal, the 58542 is placed in the waiting-for-trigger-state. The 
default configuration is continuous initiation, INIT:CONT ON.

INITiate[:IMMediate] causes the power meter to exit the idle state and causes the trigger system to 
initiate and complete one full trigger cycle, returning to the idle state upon completion. For example, 
INITiate[:IMMediate] can be used with Peak Power Sensors to measure the power level of transient or 
one-shot pulsed microwave signals. After execution of the triggering sequence, send the FETCh? query 
command to return the measurement data from the 58542.

Perform triggering configuration with the TRIGger Subsystem commands. When TRIGger:SOURce is 
IMMediate, the measurement will start as soon as INITiate is sent to the 58542 and executed (or 
INITiate:CONTinuous ON sent and executed).

INIT:CONT

Syntax:

INITiate:CONTinuous

space

<ON | OFF>

Example:

OUTPUT @PWR_MTR;INIT:CONT ON

! CONTINUOUS TRIGGERING

Description:

This allows user control of measurement cycle arming. When INIT:CONT is set to ON, 
measurement cycle arming occurs automatically. The default setting is OFF. To take control of 
arming the triggering of the measurement cycle, set this control to OFF and use MEAS#? or 
INIT with READ#? to perform the measurement. Another legal measurement control option 
would be INIT with TRIG: IMM and FETC#?

When INITiate:CONTinuous is ON, the instrument triggering cycle resets continuously. That 
is, upon instrument triggering, data is constantly being acquired and updated. Upon 
completion of a trigger cycle, the meter will immediately enter the wait-for-trigger state rather 
than the idle state, as is the case with INITiate:CONT OFF.

INIT:IMM

Syntax:

INITiate[:IMMediate]

Example:

OUTPUT @PWR_MTR;INIT

! INITIATE INSTRUMENT TRIGGERING CYCLE

Description:

This command enables the triggering cycle. Instrument triggering will not occur unless INIT 
has been enabled, even when sending BUS or EXT triggers to the 58542. Either this 
command or INIT:CONT ON performs measurements with FETCh? and READ?. MEAS? is a 
high level function which contains the INITiation enabling function. Arming occurs 
automatically when using the MEAS#? command to automatically INITiate, TRIGger and 
FETCh the measurement data. However, if using READ#? or FETCh#? to read data, this 
command arms the 58542 for triggering upon the occurrence of the next valid trigger.

The INITiate[:IMMediate] command places the power meter in the wait-for-trigger-state. When 
used with EXT (TTL levels) instrument triggering, this command is useful for measuring 
signals that are asynchronous with programming (BUS triggered) sequences. When 
INITiate:CONTinuous is set to OFF, INITiate:[IMMediate] enables the instrument triggering 
cycle. Sending INITiate:[IMMediate] when INITiate:CONTinuous is set to ON will cause a -123 
command error. The INITiate [:IMMediate] command is an event; no query form exists for this 
command.
