The Next Generation Hybrid Recorder
- A single instrument provides both oscilloscope and data logger functions -
Installing a Scanner Module Creates a Multi-Channel Data Logger
Recording slowly changing physical values such as temperature has been performed
by plotting recorders and hybrid recorders (combined numerical value and analog
graph recording), and is currently performed by data loggers. On the other hand, for
high-speed waveform observation, only an oscilloscope (or
MEMORY HiCORDER
)
can be used. However, because the demands of measurement sites can vary, having
both of these functions in a single instrument can be advantageous.

Economical Cost per Channel
The Scanner Module switches 16 input channels through one A/D converter. Of
course all channels are isolated. Cost per channel is thereby remarkably reduced
when compared to systems that include an A/D converter for every input channel.
Installing four Scanner Modules in the
8860-50
provides 64 measurement
channels, and installing eight Scanner Modules in the
8861-50
provides 128
measurement channels.

Dual-Timebase Sampling at High and Low Speeds
Depending on customers’ applications, there are cases in which high-speed
signals need to be captured as waveforms while measuring multiple channels
with a Scanner Module. Both types of signals can be measured by using a
scanner module together with a common high-speed analog module, and
recording with two different timebases. Two waveforms are displayed and can be
monitored on the same time axis.
Sheet Display Function
The Sheet function has been introduced to support multi-channel
measurements (each sheet shows 32 channels). Different display
formats can be selected for each sheet, so that each sheet can be
assigned and analyzed for a particular application.
The waveform scrolling direction can be switched between vertical
and horizontal. You can also view a continuously scrollable display to
confirm a whole long-term waveform without time-axis compression,
while simultaneously displaying time series’ and X-Y plots.

Models

support changing the compression ratio, turning the
zoom function on and off, and scroll-back display while measuring, so you can view
and analyze existing measurement data without having to wait for the measurement
process to finish.

Scroll-Back Display
An earlier portion of the waveform can be viewed without interrupt recording. This
function automatically displays earlier parts of the waveform just by turning the
Scroll knob counterclockwise. Click the Scroll Trace button on the screen, to return
the display to the current waveform position.
