Dual DMM interfaces with CompactFlash
slots
The Graphic-DMM allows any system equipped with a CF or PCMCIA slot to be turned into a dual-channel graphical digital multimeter with sophisticated analysis capabilities.
The Graphic-DMM is a new concept in test equipment that allows a PDA, notebook, tablet PC or any system equipped with a CF or PCMCIA slot to be turned into a dual-channel graphical digital multimeter with sophisticated analysis capabilities Smart analysis software facilitates step-by-step fault investigation with instant display of results and an interactive diagnostic guide

USB-based scope comes with drivers
The USBscope50 in combination with the new LabView and Agilent VEE driver support marks a new era in ultraportable modular instrumentation for the PC or notebook.
USB logic analyser runs to 4GHz
Logic analysers plug into a PC or laptop USB port making them ideal for the field service technician or engineer, hopping from PC to PC.
The Graphic-DMM can be used to integrate multiple measurement functions into a single hardware and software platform, providing high-level analysis features and a small, lightweight and portable unit.
The Graphic-DMM contains two independent digital multimeters connected to a CompactFlash type I interface.
The DMMs are galvanically isolated from the CF interface for safety, and the two channels also isolated from each other.
Each channel has its own ADC and front-end circuitry.
This means that each channel is floating relative to the other, and to the host, allowing simultaneous measurement of signals with widely different ground potentials The Graphic-DMM adds to the functionality normally found on classic DMMs: in particular it allows sample rates from less than 1sample/s up to 40Ksample/s on each channel and has a 1Mbit internal buffer (16Ksample pairs) allowing long data record depths and oscilloscope-like capabilities.
Host software can be used to create a versatile instrument that can perform accurate DC measurements, display signal waveforms and allow triggering and data logging.
In combination with a CF-PC Card adapter the Graphic-DMM can be used in any PC-Card slot equipped computer, such as a notebook, tablet PC or PC104-based embedded system, and with an Elan PCI-PC Card adapter it can also be used in any standard desktop PC, as well as CompactPCI and PXI systems.
