Information for Replacing 4278A with 4288A
Example of Replacing Major Functions (comparison of programs)
Reading out the measurement result
Continuous data output (spew-out mode)
The 4288A does not provide a continuous data output function (spew-out mode). However,
as shown in the following figure, by executing the
:READ? command and then supplying
a trigger when executing measurement, you can read out a measurement result after
completion of measurement that is similar to the as-is data output of the 4278A.
