Mass Memory (USB) Subsystem - 34972A
This section gives information on the mass memory subsystem (34972A only). The
mass memory subsystem enables you to capture data to, or import an instrument
configuration from a USB drive connected to the instrument’s USB port.
General capabilities
The mass memory subsystem suppports the following capabilities:
1
Automatic streaming of scanned data to USB drive during scan.
– Files are automatically named.
– Data is logged to USB drive and reading memory simultaneously. Most
internal operations of the instrument continue to operate on reading
memory.
– If you are using
TRIGger:COUNt INFinity
and capturing more than
50,000 readings, reading memory will fill and then overflow, discarding the
oldest data. The USB streaming will continue after reading memory
overflows, allowing you to capture all of the data (up to 2
32
sweeps, or up
to the limits imposed by the USB drive).
2
Copying of data from reading memory to USB drive
– Files are automatically named.
– After a scan finishes, you can export reading memory to your USB drive (up
to 50,000 readings).
3
Setup of your instrument based on channel configurations specified in
Keysight BenchLink Data Logger.
– Keysight BenchLink Data Logger allows you save configuration (BLCFG)
files on the USB drive. You can then import the file on the USB drive into
your instrument.
There are two annunciators related to the USB drive:
MEM
(on) - Indicates that a USB drive is connected to the 34972A.
MEM
(flashing) - Indicates the the USB drive is either streaming data to USB
(logging), copying from reading memory to USB (exporting), or importing a
configuration from Keysight BenchLink Data Logger.
