Saelig Company, Inc., announces the availability of the Aim-TTi QPX750SP 750W Single Output DC Power Supply that can provide voltages between 80V at 9.4A and 12V at 50A with a maximum resolution of 0.1 mV.

This laboratory power supply is designed to provide a flexible choice of voltage and current to meet multiple application needs. It is housed in a compact 3U half-rack width case with front ventilation and low noise fan assisted cooling.

Front and rear power and sense terminals make it suitable for use either on the bench or in a rack-mount system. The available RM460 4U rack kit can accept one or two QPX750SPs with 1/2U rack spacing above and below to provide full ventilation.

The QPX750SP features a SELV mode, an added safety feature where voltages above 50V require authorization from the user. The QPX750SP’s PowerFlex+ design uses a linear final regulation design which minimizes ripple and improves dynamic performance. This design results in an unusually low noise/power ratio, coupled with good transient response.

Three operating modes for the QXP750SP are provided — Constant Voltage, Constant Current, or Constant Power — with automatic cross-over dependent on output setting parameters CV, CC, or CP mode indication in the display.

A 4.3” color touchscreen simplifies operation and enables data entry via touch input in addition to the numeric keypad and rotary encoder. Comprehensive information is displayed for operational settings and limits for voltage, current, or power (watts).

Equivalent resistance measurements of the connected load can be made at high currents using the remote sense terminals to create a four-terminal connection. This gives more reliable results for long power leads or components such as magnetics and cables harnesses. Feature include:

  • Wide range of voltage/current combinations.
  • Up to 80V and up to 50A within the same power envelope.
  • Low output ripple and noise of <3 mV RMS at full power.
  • High setting resolution of 1 mV.
  • Analog control interfaces for voltage and current.
  • Bench or rack mounting, front and rear terminals.
  • LAN (LXI), USB (GPIB optional).

A comprehensive array of interfaces including USB, LAN/LXI, and quasi-analog are standard, with GPIB available as an option. The QPX750SP is compatible with Aim-TTi Test Bridge software, providing graphical remote instrument control, logging, and sequencing. Price is $1,550.


Saelig Company also introduces the new 750 MHz and 1 GHz models to the four-channel PicoScope 6000E Series, which provide eight to 12 bits of vertical resolution, and up to 5 GSa/s sampling rate with 4 GSa memory, allowing these scopes to display single-shot pulses with up to 200 ps time resolution.

The four new four-channel models added to the existing 6000E series are the PicoScope 750 MHz 6405E and the 1 GHz 6406E with eight-bit A/D resolution, and the PicoScope 750 MHz 6425E and the 1 GHz 6426E with 8, 10, or 12 bits ‘FlexRes’ resolution. The screen update rate is a remarkable 300,000 waveforms per second.

An active probe interface on these scopes allows the use of optional matching 750 MHz or 1.3 GHz active probes.

Pico ‘FlexRes’ flexible resolution oscilloscopes allow the scope hardware to be configured to optimize either the sampling rate or the resolution: a fast (5 GSa/s) eight-bit oscilloscope for looking at digital signals; a 10-bit oscilloscope for general-purpose use; or a high-resolution 12-bit oscilloscope for audio work and other sensitive analog applications.

All models can operate with an extra four bits of resolution with the enhanced vertical resolution software feature: a digital signal processing technique built into PicoScope 6, the complementary software.

Additionally, these oscilloscopes offer eight or 16 optional digital channels when using the plug-in TA369 MSO pods, enabling accurate time correlation of both analog and digital channels.

All 6000E models include a 14-bit 200 MSa/s 50 MHz arbitrary waveform generator (AWG). Its variable sample clock avoids the jitter on waveform edges seen with some fixed-clock generators and allows the generation of accurate frequencies down to 100 μHz.

AWG waveforms can be created or edited using the built-in editor, imported from oscilloscope traces, loaded from a spreadsheet or exported to a .csv file. The SuperSpeed USB 3.0 interface and hardware acceleration ensure that the display is smooth and responsive, even with long captures. The free PicoScope 6 software includes decoders for over 20 serial protocols.

With up to a million points, PicoScope’s FFT spectrum display has excellent frequency resolution and a low noise floor. Easily display a spectrum plot of the active channels, with a maximum frequency of up to 500 MHz. Using a 4K monitor attached to the controlling PC, PicoScope 6 software can display more than ten times the information of ordinary oscilloscopes.

PicoScope software also supports dual monitors, allowing instrument control and waveforms displayed on one, and large data sets from serial protocol decoders or DeepMeasure results on the second monitor.

The 6000E series four or eight analog channels have the timing and amplitude resolution that is needed to reveal challenging signal integrity problems such as glitches, runts, dropouts, noise, distortion, and ringing.

The 6000E oscilloscopes are ideal for design engineers working with signal processing, power electronics, mechatronics, and automotive designs, and for researchers and scientists working on multi-channel high-performance experiments in physics labs, particle accelerators, and similar facilities.

The compact size (9.7 x 7.6 x 2.5 inches) of the PicoScope 6000E series means that it fits easily on any workbench, whether in the laboratory or for mobile or even home office engineering work, and at a much lower cost than an equivalent stand-alone bench scope.

Cal Test Electronics introduces its new Instrument grade RF coaxial cable assemblies. This new family uses RG142B/U, 50Ω double shielded coaxial cable offering higher bandwidth than standard RG58 cable and yet is cost-effective for general usage. It includes the most commonly used coaxial connectors — N-Type, SMA, and BNC — in five convenient assemblies.

These assemblies feature Cal Test’s Instrument grade coaxial connectors. Instrument grade comes just below Metrology grade — the highest grade for connectors. With Cal Test’s Instrument grade RF coaxial cable assemblies, users can come as close as possible to the performance and tight tolerances of Metrology grade, yet retain cost-effectiveness and durability to meet everyday testing needs whether interconnecting an oscilloscope, spectrum analyzer, VNA, or arbitrary waveform generator.

The family offers a complete line of commonly used male (plug) coaxial connectors:

  • N-Type to N-Type
  • N-Type to SMA
  • N-Type to BNC
  • SMA to SMA
  • SMA to BNC

With all the connector options, plus two convenient lengths (60 or 100 cm), a full family of Instrument grade RF coaxial cable asssemblies are available for the lab, production line, or service department.

Features include:

  • Double Shielded RG142B/U Coaxial Cable
  • Impedance: 50Ω
  • Frequency Range: DC–8 GHz (depending on connector)
  • Excellent VSWR
  • RoHS 2 Compliant

Pricing starts at $42.25.


Cal Test also introduces a new DMM kit with enhanced safety as its focus. The CT4422 Fused Probe DMM Electrical Kit includes:

  • CT4300 — Cal Test’s New Fused Probes (black and red pair)
  • CT4439 — Fully Insulated CAT IV Alligator Clips (black and red pair)
  • CT3754 — Silicone Jacketed, Straight to Right Angle 4 mm Sheathed Banana Plug Test Leads (black and red pair)

The CT4300 fused probes easily connect to the CT3754 leads which, in turn, connect to a handheld or bench DMM. The probe’s small compact bodies feature an internal 1,000V 500 mA, fast acting ceramic fuse which can cut power in the event of a transient over-voltage, thereby protecting both equipment and — more importantly — personnel working in high energy environments. The closer the fuse is to the test point, the higher the level of protection.

The fused probe is rated at 1,000V CAT III/600 V CAT IV and features a unique locking tip cover. With this cover in place, only 4 mm of the tip is exposed, thereby reducing short circuits and arc-flash risks while working in high category environments.

Removing the tip cover limits the probe to 1,000V CAT II. The locking tip covers require a tool such as a small screwdriver to remove.

The internal 500 mA fuse is easily replaced by twisting the probe body.

In lower energy CAT II environments, removing the tip cover allows access to its standard Ø2 mm diameter by 19 mm length tip and attachment of Cal Test’s CT4439 medium alligator clip adapters for a wider array of applications.

The CT4439 comes fully insulated, including both top and bottom jaws, to prevent short circuits. With jaws opening to 9 mm, this alligator clip can easily fit conductors up to 7 mm and the three-incisor mouth ensures a stable grip on screw heads. The alligator clip is also rated at 1,000V CAT III/600V CAT IV.

Although most modern meters provide some type of over-voltage protection, using a fused probe is a prudent investment in overall user safety.

Features include:

  • Enhanced user safety in high-energy applications.
  • Rated to 1,000V CAT III/600V CAT IV per IEC/EN 61010-031.
  • Fast-acting type FF 500 mA ceramic fuse for transient over-voltages or arc-flash protection.
  • Tool-removable locking tip cover.
  • Easy fuse replacement.
  • Alligator clip jaws open to 9 mm.
  • CE listed — LVD and RoHS 2 compliant.

Price is $70.

Embedded Studio is SEGGER’s cross-platform integrated development environment (IDE) for embedded systems development. The editor is quick to start up and the build process is fast, saving precious working hours. Embedded Studio contains SEGGER’s own runtime and floating point libraries, compilers, and linkers.

All of these components were developed from the ground up specifically for resource-constrained embedded systems and are extensively used internally at SEGGER, and are continuously updated and developed. SEGGER’s primary development goal is to create fast programs that can easily be tailored to the target system and require as little memory as possible.

Optimizations are made at various stages of the build process to reduce code size and improve execution speed. The linker can make optimal use of the typically small memory of microcontrollers. Code blocks can be distributed over several memory areas and unusable memory locations can be omitted.

Embedded Studio supports all the features that characterize J-Link and J-Trace, such as unlimited breakpoints in Flash memory or RTT (Real Time Transfer).

For educational and non-commercial purposes, Embedded Studio can be downloaded free of charge and without registration at https://www.segger.com/products/development-tools/embedded-studio.

There are no restrictions in terms of code size, feature, or duration of use.

The power efficiency of the Renesas RE Family of MCUs (including the RE01-256K) combined with the low resource usage of SEGGER software minimizes or sometimes even removes the need to recharge or replace batteries. This combined efficiency could have far reaching effects for home and building automation, smart farming, factories, a wide range of medical devices, wearable applications, and more.
