USBscope50 - 1Gsps/100MHz USB Modular Scope Pen Now multi channels or multi Instruments USBscope50 marks a new era in ultra portable modular instrumentation for the PC or notebook. Using a USB1.1 or USB2.0 port on the host computer, USBscope50 offers the best of all worlds for converting your PC into a powerful diagnostic tool: tiny size, low power, low cost, modularity and high performance. A single USBscope50 can be operated as a one-channel scope, or can be stacked with other USBscope50s to make a multi-channel solution. In this configuration, each module shares its phase and trigger status with the other modules in the stack ensuring tight channel-to-channel matching and concurrent triggering, plus each module retains a dedicated USB connection to the host ensuring independent configurability. USBscope50 is small enough to be carried in a shirt pocket or laptop bag and yet retains features normally reserved for scopes 10 times its size. It uses standard BNC type scope probes, and is powered directly from the host port. It can be directly plugged into a host USB port or can be connected via a standard male-to-female USB cable. In multi-channel mode, this cabled operation is required and typically an external USB Hub would be used to provide the extra USB ports.

USBwave12 -- 12.5MHz USB pen-style Function Generator USBwave12 is a new concept in USB function generator products. PC based function generators offer many user benefits including flexibility, ease of use and economy. The USB interface has developed into probably the best and most widely implemented PC peripheral connection method and is a natural choice for the function generator. USBwave12 combines very small form factor with high performance normally associated with much larger bench type products. Power for the function generator is provided via the USB interface connector, further simplifying the user experience. USBwave12 is small enough to be carried in a shirt pocket or laptop bag but uses a standard BNC connector Technical Features USB Interface Comes with Windows USBwave12 software for 98SE/2K/XP Sine, square and triangle wave output 0 to 12.5MHz frequcy range with a 0.2Hz resolution 0 to +/-10V amplitude range with a 20mV resolution 0 to +/-10V offset range with a 20mV resolution 50 Ohm output impedance Output can also be tri-stated to protect sensitive circuitry whilst the function generator is set up Uses Direct Digital Synthesis (DDS) for excellent stability User programmable frequency and phase Output is galvanically isolated from USB port to 300V Cat II Up to 4 units can be snapped together. The outputs will be synchronised and phase shiftable Same form-factor as the Elan USBscope50 Digital Oscilloscope Can be snapped together with a USBscope50 to form part of a suite of instruments Body is approx. 75mm x 31mm x 17.5mm

USBpulse100 --- 100MHz USB pen-style Digital Pulse & Clock Generator USBpulse100 is a new concept in USB Digital Pulse/Clock Generator products. PC based pulse generators deliver many user benefits including flexibility, ease of use and economy. They are an invaluable tool during design and debug of digital circuits and can be used to quickly test the behaviour of a circuit under different input frequency and duty cycle conditions. The USB interface has developed into probably the best and most widely implemented PC peripheral connection method and is a natural choice for the USBpulse100 Pulse Generator. USBpulse100 combines very small form factor with high performance normally associated with much larger bench type products. Power for the Pulse Generator is provided via the USB port on the host - no additional power is necessary. The output is galvanically isolated from the USB bus / PC ground meaning that pulse / clock signals can be injected differentially from the USBpulse100 into the circuit under test. USBpulse100 is small enough to be carried in a shirt pocket or laptop bag but uses a standard BNC connector. Multiple USBpulse100 units can be stacked together, as well as with other items from our USB test and measurement to offer a complete instrument family. Technical Features USB Interface Comes with Windows USBpulse100 software for 98SE/2K/XP Square wave 50% duty output or variable duty cycle using combination of PLL and 28-bit programmable divider 11.6mHz to 100MHz frequency range 128 bit pseudo random bit stream generator mode clocked from programmable source Output drive level programmable in 256 steps from 1.5V to 5.0V which supports most popular logic interface standards 3ns rise and fall times typical 50 Ohm series output impedance typical Output can be tri-stated and inverted Continuous run or single shot capability with pulse widths from 10ns to over 80s, clock bursts from 1 pulse to millions of pulses or pseudo random bursts from one bit to millions of bits Output is galvanically isolated from USB port to 300V Cat II Up to 4 units can be snapped together. The outputs can be synchronised and phase shifted Can be snapped together with a USBscope50 to form part of a suite of instruments Body is approx. 75mm x 31mm x 17.5mm

USBcount50 -- 50MHz USB pen-style Frequency/Period Counter USBcount50 is a new concept in USB Frequency counter products. PC based frequency counters deliver many user benefits including flexibility, ease of use and economy. They are an invaluable tool during design and debug of digital circuits and can be used to quickly to verify generated frequencies, pulse widths and duty cycles. The USB interface has developed into probably the best and most widely implemented PC peripheral connection method and is a natural choice for the Frequency Counter. USBcount50 combines very small form factor with high performance normally associated with much larger bench type products. Power for the Frequency Counter is provided via the USB interface connector, further simplifying the user experience. The input is galvanically isolated from the USB bus / PC ground meaning that signals from unit under test do not need to be referenced to the ground of the PC. USBcount50 is small enough to be carried in a shirt pocket or laptop bag but uses a standard BNC connector. Technical Features USB Interface Comes with Windows USBcount50 software for 98SE/2K/XP Measures frequencies up to 50MHz using internal reference periods of 0.1s, 1s or 10s. 100MHz count rates also possible if input signal amplitude is sufficient to trigger input threshold Measures periods from 10ns to over 268s using internal reference clocks of 100MHz, 10MHz or 1MHz. Using period mode allows reciprocal measurements for frequencies down to 4mHz. 28-Bit internal counter gives huge 268 million : 1 dynamic range...almost no need to ever change range ! Input supply programmable to from 1.5 to 5.0V in 256 steps supporting most popular logic interface standards. Input is over-voltage protected to 30V 1Meg // 20pF input impedance Input is galvanically isolated from USB port to 300V Cat II Up to 4 units can be snapped together and share common clock Same form factor as the Elan USBscope50 Digital Oscilloscope.

USB : the Universal Serial Bus USB is a standard for connectivity; most new computers have several USB ports and almost every peripheral device you can imagine is available with a USB interface. New operating systems recognise USB devices automatically making USB very simple for the user. USB Devices include : printers, scanners, mice, joysticks and other gaming accessories, digital cameras, webcams, modems, speakers, microphones, telephones, networking devices and storage/memory. Up to 127 devices can be connected, although you'd need a few hubs to obtain that many ports on most computers. You can even connect devices up to 5 meters away from the host. USB has been with us for a long time, but the USB2 specification has expanded the variety of applications that USB can support. This specification was developed by a group called the USB 2.0 Promoter Group (Compaq, Hewlett Packard, Intel, Lucent, Microsoft, NEC and Philips), and was released in April 2000. USB 2.0 is approximately 40 times as fast as USB 1.1, offering speeds of 480 Mb/s. more....
