Field Measurement has never been easier
The
MEMORY HiCORDER 8835
-01
is a high-speed waveform recorder with
the special features of advanced performance of the basic “wave recording”
function for easy field measurement, easy-to-see color display, compact
dimensions of an A4-sized paper, and 4/8* channels for measurement. The
MEMORY HiCORDER 8835
-01
inherits all the functions of the
MEMORY
HiCORDER 8835
and accommodates a total of 8* channels when used with
the input unit group to support a wide range of signals. The
8835
-01
also comes
standardly equipped with 8x the memory of the previous unit, making long-term
recording possible.

A LAN-Connectable Recorder! Digitally Process
Test Data
With a conventional pen recorder, even if all test data is written on the
paper, usually only a small portion of the data is needed. However, to
look for just a small important part requires very extensive search of the
recording paper.
The MEMORY HiCORDER
8835
-01
stores
and manages all waveform measurement data
electronically. Furthermore, use of a LAN card
and the LAN COMMUNICATOR
9333
enables
high-speed data file transfer to PCs on a
network.

Large memory capacity allows long-term
recording of high- speed data
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.

- Function Details -
Outline of recorder function
The input signal is converted to digital form and displayed
and printed in real time. The chart speed is a maximum of
20mm/s (in the 500ms/division range). Even with real-time
recording, the last 2000 divisions of the waveform can be
observed (by scrolling both horizontally and vertically) and
reprinted following measurement.
Recording Time of the Recorder
Virtual recording
The
8835
-01
supports a high-speed recording function in the
memory with no need for recording paper. Although real-
time recording on the recording paper is not possible in the
high-speed range of the recorder function (10ms to 200ms/
division), the waveforms are stored in the memory and can
therefore be monitored on the screen. The last 2000 divisions
of the waveform are retained in the memory before the
measurement is completed. If the recording length is not set
to “continuous”, the printer can also be operated, allowing
waveforms to be printed out later.

Continuous X-Y recorder function
This function allows two signals converted to digital form to
be combined in an x-y plot and stored in memory. Any of the
four analog channels can be used for an x-y plot, and up to
three x-y plots can be combined. The x-y plot can be viewed
on the screen in real time, and the recording time is unlimited.
The x-y plot can also be reprinted.
Effective value (RMS-value) recorder function
This function is designed exclusively for use on 50/60Hz
power supply lines and DC. High-speed sampling is applied to
calculate the rms value from the waveform data, and the result
is recorded as a graph.
Note: Using fixed 200μs sampling, data for two waveforms are captured for
calculating the rms value. This process is repeated 20 times per second,
resulting in high-speed response that is 10 times faster than that of a digital
tester or similar (using a 2-second update rate).

Support for connection to PCs via Ethernet
8835
-01
can be connected to Ethernet, a standard network
protocol in the Internet age
(using the optional
LAN CARD
and
LAN
COMMUNICATOR 9333)
. For those who frequently analyse
measurement data on PCs, this function offers a good match.
Also, connection to PCs using RS-232C connection or GP-IB
connection is possible
(using the optional
RS-232C CARD 9557
and
GP-IB CARD 9558)
.
8835
-01
data can be sent to PCs or be
remotely controlled from PCs.
* Because LAN card, GP-IB card, and RS-232C card all use the same PC card slot of
8835
-01
, when one of them is inserted into the PC card slot, then any memory card cannot
be used at the same time.

also be saved to text files (CSV format) which can be opened by PC spreadsheet
applications, or waveform bitmap files (BMP format). However, because data
saved in text files cannot be read by

it is recommended that text
