Time Capture Functions
Capture transient events for repeated analysis in
FFT, octave, order, histogram, or correlation modes
(except swept-sine). Time-captured data may be
saved to internal or external disk, or transferred
over GPIB. Zoom on captured data for detailed
narrowband analysis. Up to 750K samples of data
can be saved in the standard unit.
Data Storage Functions
Built-in 3.5 in., 1.44-Mbyte flexible disk also sup-
ports 720-KByte disks, and 128-Kbyte NVRAM disk.
Both MS-DOS
®
and HP-LIF formats are available.
Data can be formatted as either ASCII or Binary
(SDF). The 35670A provides storage and recall
from the internal disk, internal RAM disk, internal
NVRAM disk, or external GPIB disk for any of the
following information:
