Introduction
Selectable recording medium that best matches what
you record
A choice of recording media allows you to select the medi-
um that best matches the application, like choosing memory
when recording fast phenomena and choosing an AIT or MO
drive when recording a great amount of data. (See the table
below.) The measured data can also be recorded directly to
a PC (e.g., to a hard disk) via SCSI. (We term this PC-direct
mode real-time transfer. In this mode, the real-time moni-
toring introduced next is unavailable.)
Real-time monitoring
Using the provided software "GX Navi", you can monitor
recorded data on a PC window as real-time waveforms or
bar graphs, and you can also perform real-time FFT analy-
ses. The waveforms of data recorded in memory or remov-
able medium can later be displayed, and scrolled through, in
a window. (Bar graph and FFT displays are possible for
sampling frequencies of 50 kHz or less, and waveform dis-
plays are possible for 200 kHz or less.)
Multi-sampling
From the internal clock frequencies, you can select a base
sampling frequency and 10 times the base sampling frequen-
cy at a time. This enables you to record fast phenomena and
slow phenomena at the same time besides saving storage
capacity.
Available internal clock frequencies:
1, 2, 5, 10, 20, 50, 100, 200, 500 Hz, and 1, 2, 5, 10, 20, 50,
100, 200, 2.5, 12.5, and 25 kHz
Notes:
• The sampling frequencies are set slot by slot, not channel
by channel.
• The total of [sampling-frequency x number-of-channels]
must not exceed 3,200 kHz.
• Some commercially available analytical software cannot
read the data files recorded by multi-sampling. Contact us
for details.

Features

Voice memo recording/playback
You can record and play back voice memos.
External-clock sampling
Sampling can be performed based on an external clock sig-
nal.
Various recording modes
· Manual start mode: Recording is started manually.
· Pre-trigger mode: Data is continuously stored so that
data from a specified time before
the occurrence of the trigger can be
recorded in memory.
· Post-trigger mode: Recording is started at a specified
time after the occurrence of the
trigger.
· Level-trigger mode: Recording is started when a speci-
fied change occurs in the signal
level of a specified channel.
· Timer mode: Recording is started at a specified
time.
Event marks
You can attach event marks to desired points in data during
recording. You can later search through the data to find
attached event marks.
Analog reproducing
Data recorded in the internal device — memory or removable
medium — can be reproduced in waveform display. With the
optional analog output amplifier, you can reproduce the
recorded data as analog signal.
Clock correction by IRIG-B time code
The internal clock can be corrected by an external IRIG-B
time code signal.
