9.3 Storage
The GEN3i provides two storage paths, as shown in Figure 9.1 on page 131:
l
Store data in on
-
board RAM at high speed
l
Transfer data directly at reduced speed to the controlling PC or (when
installed) to a local disk.
In addition to these storage paths, the GEN3i provides two fundamental storage
modes:
l
Sweeps: data storage of predefined length. Sweeps typically use a trigger
to define the start and end of the sweep.
l
Continuous: data storage of an undefined length. The end of this storage
mode can be defined by various events, as described later.
When data is stored, this data is organized in recordings. A recording is defined
as all the data that has been stored between the start of acquisition (Record
command) and the end of acquisition. The end can be defined in various ways.
A recording can have one or multiple sweeps, a continuous data stream or a
combination of both.
In Perception, a recording is organized as a PNRF file (Perception Native
Recording File).
CAUTION
The GEN3i RAM is volatile. Wait until all data is transferred to the
recording file before closing Perception or switching off the instrument.
The storage mode defines how data is digitized and saved. The continuous
storage mode stores all data. The sweep storage mode stores only the sweeps.
However, the resulting file
-
or recording
-
will be different for the various storage
modes.
