Single-device Solution for Waveform Recording and Generation,
High-speed 16-channel/Isolated Multi-channel System Recorders (rack-mounted)
MEMORY HiCORDER MR8741
The MR8741 is rack-mountable data acquisition system that delivers high-speed, multi-channel measurements over maximum of 16 channels. The MR8990 DVM module is a 2-channel input unit for the MR8741 for measuring minute fluctuations in output from sensors in automobiles and other equipment and voltage fluctuations in devices such as batteries at high levels of precision and resolution.
Use with the Arbitrary Waveform Generator Unit U8793 to create a function generator, arbitrary waveform generator, and waveform measurement in a single device.
• Introducing the DVM Unit MR8990 with high 24-bit resolution! Perform high-speed, high-accuracy measurement without going through a scanner.
• Support for multi-channel measurement (MR8741: up to 16 ch)
• Isolated input (between input channels; input-to-chassis isolation: maximum input-to-ground rated voltage of 300 V AC/DC)
• High-speed sampling (max. 20 MS/s)
• Ideal for rack-mounting (4U height/within 180 mm; display-less, box-type design)
• Display waveforms and make settings on a DVI-D connected monitor and mouse
• Remote measurement via LAN using control commands from a PC
*Screen monitoring and remote operation available via Internet browser. For faster and more convenient remote operation, we recommend using the Hioki 9333 LAN Communicator.
