4-ch Channel High Resolution Oscilloscope With Differential Inputs

The PicoScope 4444 High-resolution Differential Oscilloscope features four true differential input channels and a range of accessories for measurements from millivolt to 1000 V CAT III applications. It has been designed specifically for making accurate voltage waveform measurements on circuits that are not ground-referenced, avoiding the dangers of equipment damage due to short circuits.

The PicoScope 4444 can facilitate differential voltage measurements in the presence of common-mode signals, with 14-bit resolution and 20MHz bandwidth on all four differential channels and 256MSa waveform capture memory. It is ideal for the precise analysis of complex waveforms ranging from biomedical sensors to current probes and 1000 V CAT III power distribution circuits. The PicoScope 4444 offers a choice of complementary 1:1 low-voltage and 25:1 1000V CAT III probes to address these and other situations. The oscilloscope has an intelligent probe interface that can provide power for a wide range of PicoConnect voltage probes, current probes such as Hall effect DC/AC, and Rogowski coil type active current probes. The scope automatically detects when a compatible probe is connected and sets the corresponding units and vertical settings in the supplied PicoScope 6 software.

The USB-powered PicoScope 4444 is available in two kits that include key accessories:

·         PicoScope 4444 Standard Differential Oscilloscope Kit, consisting of a PicoScope 4444, three differential 1:1 probes and one TA271 BNC single input adaptor.

·         PicoScope 4444 1000 V CAT III Differential Oscilloscope Kit, consisting of a PicoScope 4444, three 1000 V CAT III 25:1 differential probes and one BNC input adaptor.

Scientists and electronics engineers frequently need to make low-voltage measurements in the presence of high common-mode noise or varying offset voltages. Ground-referenced oscilloscopes require the use of two input channels and an A–B math function to observe the differential signal of interest. But, in addition to requiring two input channels, most scopes don’t have a high enough common-mode rejection ratio (CMRR), nor the resolution to make measurements with sufficient precision.  Engineers working on polyphase power distribution systems need to measure phase-to-phase AC voltages, rather than phase to ground. A ground-referenced scope can’t be used as it will cause a short circuit. External differential probes are a solution but they are quite expensive and cumbersome, with each probe requiring its own power supply. The PicoScope 4444 provides the solutions for each of these situations, but it can also be used as a general purpose scope with all the useful features that PicoScope software provides - such as serial bus decoding, mask and limit testing, math channels and automatic measurements.
Made by Pico Technology, Europe’s award-winning oscilloscope adapter manufacturer, PicoScope 4444 High-resolution Differential Oscilloscopes are available now from Saelig Company, Inc. their USA technical distributor.

SDG6000X: New Economical 500MHz Dual-Channel AWGs with great specs from Siglent

Saelig Company, Inc. has introduced Siglent’s SDG6000X series of Dual-Channel Pulse/Arbitrary Waveform Generators that create test signals up to 500MHz using a sample rate of 2.4GSa/s and 16-bit vertical resolution for an 80dB dynamic range. This series features Siglent’s proprietary TrueArb and EasyPulse technologies that solve the weaknesses inherent in traditional DDS waveform creation.  TrueArb technology generates arbitrary waveforms “point-by-point” to produce a very low jitter (< 150ps) output signal from stored memory.   Rapid rise and falling edges are enabled with the EasyPulse design, unaffected by frequency setting, extreme duty cycle, or extreme edge and width settings.  The SDG6000X generators achieve extremely high accuracy performance in both time domain and amplitude, resulting in more accurately reconstructed waveforms with lower distortion, low noise floor, and excellent signal-to-noise ratio.

Available in 200/350/500MHz versions, the SDG6000X series of signal generators feature a 4.3” TFT touch screen display to provide fast operation and a clear view of settings.  Waveform rise/fall times can be set independently to a minimum of 1ns at any frequency with a minimum adjustment step as small as 100ps.  The pulse width can be fine-tuned to the minimum of 3.3ns with an adjustment step as small as 100ps, at any frequency.  These generators can produce conventional waveforms, Noise, IQ signals, and PRBS patterns with a maximum amplitude of 20V pp.   EasyWave software, provided free, is a powerful arbitrary waveform editing application that supports many means of conveniently generating or editing arbitrary waveforms, such as manual drawing, line-drawing, equation-drawing, coordinate-drawing, etc.

The SDG6000X series has independent dual generators that offer 196 built-in arbitrary waveforms with a high-precision 8-digit 0.1Hz to 400MHz dual-channel Frequency Counter that offers a statistics functionality. Standard interfaces include USB Host, USB Device, LAN(VXI-11, Socket, Telnet) with optional GPIB.

Signal generating capability includes Modulation, Sweep, Burst, and Waveform Combination. Multiple modulation types are supported, including AM, FM, PM, FSK, ASK, PSK, DSBAM, PWM. The modulation source can be configured as internal or external. Modulation sweep modes include linear and log. Burst modes include N cycle and gated. Both sweep and burst can be triggered by internal, external or manual source, while IQ signal modulation is an option.  The Waveform Combining mode superimposes CH1 and CH2 waveforms internally, outputting the resulting waveform that can be a combination of basic waveforms, random noise, modulation signals, sweep signals, or burst signals, etc.

The SDG6000X series generate high fidelity, low jitter signals to meet the growing requirements of complex applications, and they are available now from Saelig Company, Inc.

Get to market fast with the U8S Intelligent USB charging PCB

Integrate the U8S into a cart, case, trolley or desk unit to offer intelligent charging and data transfer.

Cambrionix 8 Port Universal Charge Component (U8C)

The U8S is a pre-designed module to allow a user to connect and charge 8x USB devices with a single host computer. It is a module which is ready to drop into your design to offer functionality which adds real value to your product.
The U8S should not be confused with a standard USB hub, the U8S is, like all Cambrionix products, over-engineered to provide both high current charging for 8x power-hungry USB devices as well as robust data transfer to the host and a control interface accessible via our API (application programming interface) or Live Viewer App.
In addition to being able to use an off the shelf component for your universal charging and data requirements, we offer a number of reference designs for front panel displays using both LED and LCD. These displays can be used to provide user feedback on port status, animated charging icons or arbitrary text which can be sent to the displays via our API.
These reference designs are provided free of charge and we offer design-in support.

Reliability was the number one priority when designing the U8S and as a result, we are yet to receive a statistically significant number of returned units. The U8S powers over 100,000 (one hundred thousand!) USB ports across the world for OEMs on each continent.
Our reliability means that once the U8S is built into its target system, for example a smart charging locker, you are very unlikely to experience a customer returned unit due to a faulty U8S.
Internally, the U8S has a microcontroller at its heart which allows our unique API and Live Viewer app to display information about each port and also allows the user to control those ports in a variety of ways. We have partnered with a number of component suppliers during the development of the U8S and have deep knowledge of every component used within the U8S design.
The U8S is supplied with the latest Cambrionix firmware although updating the firmware is performed quickly and easily using the Firmware Updater App which is available as a free download. We can offer new versions of firmware to add additional API features and additional charging profiles for obscure devices which may not necessarily adhere to documented standards (or not be on the market yet).
All versions of the U8S support our API which allows you to automate, monitor and control each port programatically using a variety of programming languages. With the API you can monitor current consumption of each individual port, total connection time, charging time, turn power on/off to individual ports, emulate different charging profiles, read USB VID/PID and much more.
The API consists of a service module or daemon that is loaded on the host computer. The service module is accessed via JSON-RPC calls over a TCP/IP socket. Cambrionix provides sample Python code complete with the necessary JSON library code to be able to make the necessary calls for controlling Cambrionix products that are connected to the host computer.
It is of course possible to access the API from any programming environment that has support for making JSON-RPC calls over a TCP/IP socket.
The API is available as a free download and is well documented and supported by Cambrionix engineers.
We also supply our Live Viewer App which allows you to monitor and control ports using a graphical user interface.
