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.
100MHz Battery-Portable Oscilloscopes
23 June 2022 - Saelig Company introduced the Micsig STO1004 four-channel battery-powered portable oscilloscope, which offers 100MHz bandwidth, 70Mpts memory, 1GSa/s sampling (single channel), 130,000wfm/s refresh rate, and a 7.5Ah Li battery for extended field use. Improvements over previous Micsig models include an intelligent bidirectional Universal Probe Interface for accommodating and powering smart probes such as those with differential inputs and new joystick control buttons. A smartphone app is also available for remote instrument control.
Isolated Channel PC Oscilloscope
17 June 2022 - Cleverscope introduced the CS548, a 2kV DC isolated channel oscilloscope designed to be useful anywhere isolation and high CMRR are needed - in particular power electronics, including on the high side. Using the CS1200 IsoPod allows a >30kV isolation. The new CS548 features 100 dB CMRR at 50 MHz, Frequency Response Analysis, Component LCR measurement, MSPS streaming to disk for days, high resolution spectra, sophisticated maths, Matlab and Excel live, external sampling clock, Ethernet or USB, Isolated Signal Generator, and mixed signal capture.

A Comparison between Oscilloscopes and Spectrum Analyzers
Whether it is for a land survey searching for minerals on Earth, or for a space exploration in search of alien life forms, the analysis of any signal boils down to looking at its time and frequency information. While an oscilloscope displays a signal with respect to time, a spectrum analyzer shows it with respect to frequency. Both of these tools are very important in any signal analysis application. This article explains the difference between oscilloscope and spectrum analyzer using examples.
