The data returned by commands such as
entered into the computer before another command is executed. Otherwise,
Error -410,"Query Interrupted" occurs and the data will be overwritten if
data is generated by the next command.
A few words about mainframe memory:
1. The E1301A memory is built into the mainframe whereas the
E1405A/E1406A memory is not built-in.
2. Data is stored in mainframe and shared memory by executing the
INIT
command.
3. Reading rates are increased when the readings are stored in
mainframe memory. Storing readings in memory also ensures that
the sample rate is maintained at a constant value.
