The 8835-01 can store a total of 4 mega-words, using
internal solid-state memory. This provides ample
capacity to store data for all 8 channels. The table at
right shows possible recording times, according to the
time axis setting and the number of channels in use.
A reduction in the number of channels prolongs the
recording time.

When using the memory recorder function, the data memory
can be divided into a maximum of 255 blocks. Data can be
written sequentially to the memory blocks, and the waveform
in a reference block and any other block can be superimposed
and compared.

Zoom function *In memory recorder function
To make the most of the large-capacity memory, it is possible
to display a compressed waveform simultaneously with a
magnified waveform. Since the 8835-01 is capable of storing
a large amount of data, high-speed sampling is also possible
for waveforms with a long duration. Accordingly, while
observing the compressed image of the entire waveform, it is
also possible to observe the magnified details of desired parts.
Compressed display of a part of the entire waveform is also
possible.
■
Clock input for external sampling *In memory recorder function
The sampling rate for the memory recorder can be controlled by
the timing of an external clock signal. This is useful for example to
collect data synchronized to the running cycle of an engine.
