Hitec’s RDX line of battery chargers continues with the introduction of the RDX2 200 AC/DC multifunction smart charger. Capable of charging two batteries simultaneously regardless of chemistry or capacity, the RDX2 200 allows you to connect different battery chemistries (NiMH/NiCd/LiPo/LiFe/Lilo/LiHV/Pb) into any of the two charging ports (100W per port, 200W total power), and features integrated balancing for six-cell LiPo batteries.

Designed with an easy-to-read LCD screen and sleek metal scroll wheel for simple setting selection, this twin-channel charger is also compatible with Hitec’s “Charge Manager” PC and Mac software that allows charger operation and firmware updates from a PC.

Whether you run sport-level 1/10th and 1/8th scale electric vehicles, 600+ size helicopters, or sport and giant-scale planes using up to 6S batteries, the RDX2 200 is a compact, affordable charging option for your hobby.

Estimated street price is $129.99. Dimensions are 4.6 x 4.3 x 3.1; weight is 1.04 lb.

The Analog Discovery Pro (ADP2230)™ from Digilent is a mixed signal oscilloscope (MSO) designed for professional engineers. It features analog inputs, analog output, and digital I/O, with deep memory buffers all operating at up to 125 MS/s. Users can both receive and generate digital signals to test and analyze data from various devices, while simultaneously powering those systems with its robust power supply. The feature-packed design allows the ADP2230 to perform the functions of several test and measurement devices and can replace a stack of traditional instruments.

With Digilent’s free WaveForms software, users can view and capture complex data, perform spectral and network analysis, and quickly retrieve large amounts of data.

WaveForms leverages the ADP2230’s deep buffer memory, allowing hundreds of millions of samples to be stored and streamed back to the host computer. WaveForms’ friendly user interface has the feel of traditional benchtop oscilloscopes.

The ADP2230 is part of the Digilent Analog Discovery Pro family of test and measurement devices that empower engineers, researchers, educators, and scientists to design and test with unparalleled flexibility. These customizable solutions cater to both seasoned professionals and emerging engineers, accelerating development while maintaining a low barrier to entry.

Highlighted features include:

  • USB mixed signal oscilloscope with deep memory buffers for long acquisitions
  • BNC connectors and an aluminum case
  • Two analog inputs — 50+ MHz bandwidth
  • One analog output — 15 MHz bandwidth
  • Sixteen digital input/output channels
  • Sample rates up to 125 MS/s
  • Two power supply outputs
  • USB 3.0 communication speeds
  • Sync multiple devices for increased channel count
  • Extensive software support with WaveForms, WaveForms SDK, LabVIEW, and MATLAB

Saelig Company, Inc., now has available three new series of 12-bit Siglent HD oscilloscopes designed to improve signal fidelity, visualization, and analysis, adding to the previously announced SDS2000X-HD 12-bit oscilloscopes.

The new SDS800X-HD, SDS1000X-HD, and SDS3000X-HD scopes are equipped with very low noise front-ends and advanced 12-bit analog-to-digital converters (ADCs) to yield precision signal measurements.

The Siglent HD series are next-generation oscilloscopes offering 16 times the signal resolution of traditional eight-bit oscilloscopes. These HD scopes all display signals in finer detail, make more precise measurements, have higher voltage offsets, and better accuracy than ordinary oscilloscopes.

Pricing is as follows:

  • SDS800X-HD: 70-200 MHz, 2/4-ch, 2 GSa/s, 50/100 Mpts, MSO option, 7” touchscreen, starting at $339
  • SDS1000X-HD: 100-200 MHz, 2/4-ch, 2 GSa/s, 100 Mpts, MSO option, 10.1” touchscreen, starting at $999
  • SDS3000X-HD: 350 MHz-1 GHz, 4-ch, 4 GSa/s, 400 Mpts, MSO option, 10.1” touchscreen, starting at $3690

The SDS800X HD and SDS1000X HD are all typically specified at just 70 uVrms noise at 200 MHz bandwidth. The lowest ranges are specified at 1.5% DC gain accuracy, while the ranges ≥5 mV/div have a 0.5% accuracy. The SDS3000X HD series provides up to 60 dB of channel-to-channel isolation.

Siglent’s HD oscilloscopes feature simultaneous zooming for both the horizontal and vertical directions on active signals.

This, coupled with the advantage of large memory depth, facilitates in-depth analysis and can reveal insights that are typically hidden, such as when using “voltage offset before A/D” capabilities to discover small signal anomalies far above ground, focusing the ADC just on small variations of interest.

When visualizing signals in the RF space, the ability to calculate deep memory FFTs with low noise, 12-bit data provides additional capabilities for debugging and analyzing high-speed signals.

On the SDS3000X HD range, the equivalent of up to four additional bits of resolution are available in an extended high-resolution mode (ERES) to provide even further noise reduction and flexibility.

All HD models are equipped to measure more than 50 parameters, support simultaneous mathematical operations across all channels, and feature a formula editor for enabling nested formulas.

Additionally, all three HD oscilloscope series support features like Mask Test, Bode Plot, Power Analysis, Search, and Serial Decode.

The three new HD oscilloscope ranges all have high-definition touch screens (7” or 10.1”), advanced web control, and network drive data capabilities.

The combination of an intuitive user interface with multiple one-button operations on the front panel and seamless remote access greatly improves the operating efficiency in any use mode.

With bandwidths ranging from 70 MHz to 4 GHz, 12-bit Siglent HD oscilloscopes provide outstanding signal fidelity measurements for a wide range of applications including power, EMI, frequency analysis, embedded design, and failure analysis.
