Multi-function Touch Screen Oscilloscope
09 September 2022 - Hantek released a new generation of the TO1000 series multi-function full touch screen oscilloscope. The new TO1000 series oscilloscope has a thin body, is light weight and easy to carry. Its unique hanging design enables a hands-free operation. The instrument integrates oscilloscope, multimeter, signal generator and spectrum analyzer. The built in large capacity battery offers long endurance and supports fast charging.
IEPE Signal Conditioner
19 August 2022 - Pico Technology launched a signal interface box for piezoelectric sensors. The TA487 IEPE Signal Conditioner is an interface that allows industry-standard IEPE (integrated electronic piezoelectric) sensors to be used with any oscilloscope or data acquisition device with BNC inputs. The device is powered from any USB port, using the cable supplied, and provides a 4mA constant current source to power a connected IEPE sensor.
100MHz Battery-Powered Automotive Oscilloscope
17 August 2022 - Saelig Company introduced the Micsig SATO1004 Automotive Tablet Oscilloscope with 4 channels, a bandwidth of 100MHz, an easy-use touchscreen operation and a comprehensive set of vehicle diagnostics. With its signal sample rate of 1GSa/s, the SATO1004 is a vehicle testing tool for evaluating systems such as: ABS, Accelerator Pedal, Throttle Position, Fuel Pressure, Air Flow meter, Crankshaft, Camshaft, Knock, MAP, 12/24V Charging & Start, Charging Ripple, Cranking Current Sensors, Actuators, Ignition, and Networks (CAN, LIN, Flex ray, K line, etc.)
PMBus Decoding to analyze smart Batteries and Power Supplies
15 August 2022 - Pico Technology released a Power Management Bus (PMBus) decoder to their database of free serial decoders. The PMBus decoder tool is available in PicoScope 7 (Early Access) to decode, display and analyze smart batteries and power supplies. PMBus is a serial communications protocol aimed at the configuration, control, and monitoring of power supply devices. It’s built on top of the proven foundation of the SMBus, which is a low-cost, two-wire bus derived from I2C.
30 MHz High-Voltage Differential Probes
04 August 2022 - Cal Test Electronics introduced the CT4447 Series of 30 MHz High-Voltage Differential Probes. Two different attenuation settings are offered, covering the most requested voltage ranges. Compatible with oscilloscopes (with 1 MΩ input) from all major manufacturers, the probes can be powered by batteries (included), a universal mains adapter (included), or by the oscilloscope, if USB equipped.
Battery-powered Portable 200/300MHz Oscilloscopes
13 July 2022 - Saelig Company, Inc. announced the Micsig STO2000C Series 2-channel Portable Oscilloscopes, which offer a bandwidth choice of 200 or 300MHz, 280Mpts of memory, 2GSa/s sampling rate (single channel), up to 270,000wfm/s refresh rate, and a 7.5Ah Li battery for extended field use. This portable instrument combines a capacitive 8” TFT LCD touch screen (touch, drag, and swipe) with traditional ‘button & knob’ operation to make scope operation easy and efficient. An external USB mouse can also be connected for additional control choices.
PCI Express 5.0 OCP NIC 3.0 Interposer
27 June 2022 – Teledyne LeCroy announced availability of a PCI Express 5.0 Open Compute Project (OCP) Network Interface Card (NIC) 3.0 interposer that works in combination with Teledyne LeCroy’s Summit family of PCI Express 5.0 protocol analyzers. The new OCP interposer allows engineers to test product designs that incorporate OCP NIC 3.0 with PCIe 5.0, NVM Express (NVMe) or Compute Express Link (CXL) technologies. The PCIe 5.0 OCP interposer joins the list of CrossSync PHY enabled interposers, allowing users to debug enhanced power management and link training equalization through correlated and time aligned physical and protocol layer views.

Oscilloscope Probes – Vital Link in the Measurement Chain
Signal measurement results can only be as accurate as the test and measurement tools in use. As clock rates and edge speeds of today’s electronic circuits increase, probing becomes a critical piece of the measurement system – the component that comes in direct contact with your circuit. This article looks at voltage probing considerations for embedded system and digital design debugging applications.

Digital Debugging - better using a Mixed-Signal-Oscilloscope or a Logic Analyzer?
Today’s technology is fundamentally balanced on an increasingly fine line between the analogue and digital domains; as data speeds increase — both within and between devices — the ‘ideal world’ of fast, clean digital transitions becomes evermore difficult to achieve. This presents new and escalating challenges when verifying faster digital signals that exhibit more and more analogue-like features. As a result it is becoming necessary to remove the hard line between digital and analogue.
