Reading Out Measured Result
Reading Out Measured Result
Sample Program
See
measured result in ASCII and Binary format respectively using *TRG command.
Reading out measured result using
You can use this readout method when you want to trigger the instrument from
any source other than an external controller or when you want to perform a
process that is between triggering the instrument and reading out the
measured result.
The readout procedure using the
Step 1.
Set up the trigger mode as necessary.
Step 2.
Trigger the instrument by using the method for the trigger mode.
To trigger the instrument from an external controller in this procedure, use
the :TRIGger[:SEQ1][:IMMediate]
Step 3.
Execute the
Step 4.
Read out the measured result. To repeat the measurement, repeat Steps 2 to
4.
Sample program
See
measured result in ASCII and Binary format respectively using :FETCh?
command.
Reading out measured result using
You can use this readout method when you want to read out the result
synchronously with the completion of measurement without detecting the time
of trigger in the trigger wait state in your program. Therefore, this is useful, for
example, when you want to trigger the instrument from external equipment
such as a handler and read out the result using an external controller
immediately after the completion of measurement.
The readout procedure using the
Step 1.
Use the :TRIGger[:SEQ1]:SOURce
mode to internal trigger (Internal) or external trigger (External).
Step 2.
Execute the
Step 3.
Trigger the instrument using the method for the trigger mode setup.
Step 4.
Read out the measured result. To repeat the measurement, repeat Steps 2 to
4.
