The DL850/DL850V ScopeCorders are modular, signal
waveform recording instruments that can synchronously measure
various signals such as voltage, current, strain, and acceleration.
They measure multiple physical signals for a long period at the
sites of developing products in the mechatronics area where
noise rejection is emphasized. The standard model DL850 and
the Vehicle Edition DL850V, which is primarily intended for
developing devices used in automobiles, are offered.
A total of 15 plug-in modules are available for
measurement.

FEATURES
High speed isolated measurement
Adopting high speed optical fiber-based transmissions
(isoPRM TM technology), DL850 is capable of 1 kV high
voltage isolation measurement*1 while achieving high-speed
data acquisition of 100 MS/s, A/D resolution of 12 bits,
analog bandwidth of 20 MHz.

High speed waveform display
Adopting the GigazoomEngine® 2 high-speed data
processing system applying Yokogawa’s original data
processing algorithm, DL850 can quickly display up to 2 G
points data in the memory and two zoomed waveforms.

Excellent noise rejection performance
Excellent noise rejection performance (high CMRR of
approx. 90 dB at 10 kHz for the 10 MS/s high-speed
isolation module) is achieved through exhaustive low
noise design. Even floating voltage switching waveforms of
inverter circuits can be precisely captured.

Multi-channel measurement
With maximum 8 modules of the 16-CH voltage input
module (scanner type), 128-CH voltages can be measured
at 10 kS/s sample rate. One logic input module can measure
16 relay states or sequence states simultaneously, enabling
measurement of 128 logic states with eight modules.
CAN bus monitoring (DL850V model only)
By using the CAN bus monitoring module, DL850V can
display the communication data of the CAN bus protocol in
analog trend waveforms for monitoring. Database container
(DBC) files *2 are also available.
