Now available in the UK from TTi Distribution, the Sorensen SG Series of programmable power supplies has been expanded to include a 0-800 V DC offering. This expanded voltage range makes the unit ideally suited to use in applications such as test systems for hybrid vehicles and power inverters.

The SG Series is available with 5 kW, 10 kW or 15 kW power ratings in a 3U chassis, allowing up to five units to be paralleled for a maximum system power of 75 kW. Paralleled units operate like a single supply.

The SG Series is designed for exceptional load transient response and low noise, and provides the highest power density in the industry. This power density is complemented by a stylish front air intake that allows supplies to be stacked without any minimum clearance between units.

The Sorensen SG Series is available in two control versions: SGA with basic analogue controls and SGI with intelligent control features. The SGI version combines onboard intelligent controls with high-performance power electronics that enable sophisticated sequencing, constant power mode and save/recall of instrument settings. Looping of sequences can also be implemented, making the SGI ideal for repetitive testing.

The SG Series features a high-quality vacuum fluorescent graphical display in eight languages, context-sensitive ‘soft’ keys, a front-panel keyboard, simplified programming, and an RS-232 interface.

The SGA version is suited for those customers requiring simple front-panel analogue controls or external control. It has the same high-performance power electronics as the SGI, and includes features such as 10-turn potentiometers for setting voltage and current and a 3½-digit LED readout.

Both the SGA and SGI offer optional LXI Class C Ethernet or IEEE-488.2 interfaces.

Mixed-signal oscilloscope family offers logic debug capabilities

Now available from TTi Instrument Distribution are a number of new models in the Tektronix MSO2000 Series of mixed-signal oscilloscopes, offering advanced logic debug features at an entry-level price.

With up to 200 MHz bandwidth and 1 GS/s sample rate, the instruments incorporate up to 20 channels for analysing both analogue and digital signals, allowing users to quickly find and diagnose problems in complex designs. To capture long windows of signal activity while maintaining fine timing resolution, the MSO2000 Series offers a deep record length of one million points as standard on all channels.

With Wave Inspector(R) controls for rapid waveform navigation and automated serial and parallel bus analysis, the MSO2000 provides a feature-rich set of tools to speed and simplify the debugging of complex designs.

The 16 digital channels are tightly integrated into the oscilloscope’s user interface, simplifying operation and making it possible to solve mixed-signal issues easily.

One common challenge shared by both logic analysers and mixed-signal oscilloscopes is determining if data is a ‘one’ or a ‘zero’ when the display is zoomed in so far that the digital trace stays flat all the way across the display. The MSO2000 Series addresses this issue by using colour-coded digital traces, displaying ‘ones’ in green and ‘zeros’ in blue.

The multiple transition detection hardware shows a white edge on the display when the system detects multiple transitions. This acts as a visual reminder that increasing the sample rate on the next acquisition will reveal higher-frequency information than the previous settings could acquire.

The MSO2000 Series simplifies channel setup by allowing the user to group digital waveforms and enter waveform labels via a USB keyboard. Digital waveforms are simply placed next to each other to form a group, and all the channels contained in that group can then be positioned collectively. This greatly reduces the normal setup time associated with the positioning of channels individually.

An advanced probe design incorporates two eight-channel pods, which greatly simplifies the process of connecting to the device under test. When connecting to square pins, the P6316 probe can connect directly to 8 × 2 square pin headers spaced on 0.1-inch centres. When more attachment flexibility is required, flying lead sets and grabbers (also included as standard) can be used to clip onto surface mount devices or test points. The P6316 probe offers outstanding electrical characteristics, applying only 8 pF of capacitive loading with 101 kilohm input impedance.
