Complete data capturing with a large capacity 1 Gbyte memory (optional)
- Functions -
(Fixed recording length) When you select the alternate recording length, the maximum number of divisions changes from 100,000 to
160,000, 500,000 to 640,000, and 2,000,000 to 2,560,000 respectively.
"H" Exceeds 365 days.
By using FTP client software from your PC, you can
access the files stored on media installed in the 8855.
FTP service
(to be supported from version 2.00 of this unit)
Using a modem card, you can connect the LAN to your
PC via a telephone line using PPP. This enables you to
connect a PC in your office to an 8855 set up in a remote
location using a modem, and to access files via FTP or the
LAN COMMUNICATOR 9333.
PPP connect function
(available from version 2.10 of this unit)
Large volumes of stored waveform data can be analyzed
and processed using a PC. Media such as MOs, PC cards,
or floppy disks, or interfaces such as LAN or SCSI can be
used to transfer data.
Data compatibility with PCs
Ethernet
Waveforms captured in memory mode can be processed
through such operations as the four basic arithmetic
operations, as well as differentiation and integration.
Furthermore, maximums and other parameters of the
observed waveform data can be displayed. Using this
function, signals can be analyzed in a many different ways.
Calculation function
Actual measurements usually involve parameters other
than voltage. Therefore, various physical parameters such
as speed, vibration, or temperature commonly need to be
monitored. In such measurement conditions, the scaling
function can be used to automatically convert to the desired
parameter.

The 8855 allows you to observe X-Y composite
waveforms (Lissajous waveforms) that occur between
two signals. Any channel can be set as the X or
Y axis. In addition to its composition capacity in
memory mode, the 8855 can display real-time images
of unlimited recording time in recorder mode.

Waveform judgment function
After defining a reference waveform area, you can
use area judgment to check whether the waveform
displayed on the screen extends outside that area.
With parameter judgment, you can evaluate results of
numeric calculation with set values.

The 8855 comes equipped with a standard memory
capacity of 32 Mwords, but you can increase this by four
times (128 Mwords total) or as much as 16 times (512
Mwords total) by using the optional memory available. The
maximum recording times are displayed in the table on the
right according to the time axis range setting.
