trigger subsystem goes to the WTG (Waiting For Trigger) state. When a software
trigger is applied with the TRIGger:SEQuence3 or *TRG common command, the
measurement action is executed. When an ABORt or an equivalent command is sent
without executing the trigger, the measurement action is cancelled, and then the
trigger subsystem returns to the IDLE state.
The ABORt command and IEEE488.1 sdc/dcl commands simply abort the
measurement task that is in progress. It does not have a feature to invalidate any
measurement data that has been acquired. On the other hand, the *RST and *RCL
common commands not only abort the measurement task, but also invalidate the
acquired measurement data. This means that the “*RST;:FETC:VOLT?” command
will generate an error, because no measurement data can be fetched and there is no
new measurement is scheduled.
The only difference between MEASure (or READ) and FETCh commands is that
the MEASure command starts a new measurement while the FETCh command does
not. Availability for measurement items is exactly the same for MEASure and
FETCh.
Generating and Clearing the measurement data
The measurement data is stored in the measurement data cache for the mean value
of the moving average deviations of 64 times measured in every 4 ms. The mean
value of the moving average returns after 4 ms counted from the measurement
begins upon receipt of the "INIT:SEQ3" command. Despite the setting of the
"INIT:CONT:SEQ3" whether on or off, it will start the measurement in every 4 ms
and display the mean value of the moving average deviations of 64 times.
The "INIT:SEQ3/INIT:NAME ACQ" command is a command that invalidates the
current measurement data stored in the present measurement data cache and it
begins a new measurement. The new measurement data will be established after 4
ms.
The "SENSe:AVERage:CLEar" command clears the measurement data stored in the
cache and it does not return the query of "FETC" command until the moving
average of 64 times is established. This "SENSe:AVERage:CLEar" command is a
command that clears all the measurement data of the mean value of the moving
average deviations of 64 times as when the setting of the voltage or the current value
changes frequently or to change rapidly to be monitored. Therefore, after
transmitting the command, new moving average of another deviations of 64 times
will be generated after 256 ms.
