element14 launches BitScope Micro for Raspberry Pi
07 November 2014 - element14 has partnered with BitScope Designs to manufacture and distribute BitScope Micro, a full feature dual channel digital oscilloscope for Raspberry Pi. BitScope Micro is also an eight channel logic analyser, waveform generator, clock generator and spectrum analyser all packaged in one low cost lightweight water resistant test probe. BitScope Micro captures digital signals at up to 40 MSps and has a 20 MHz analogue bandwidth.
Software Option to increase vertical Oscilloscope Resolution to 16-bit
07 November 2014 - With the high definition (HD) mode Rohde & Schwarz increases the vertical resolution of the R&S RTO and R&S RTE oscilloscopes to up to 16 bits - a 256-fold improvement over 8-bit resolution. Waveforms are sharper and show signal details that would otherwise be masked by noise. Users benefit from even more precise analysis results.
Oscilloscope Probes for High-Voltage Signal Measurements
05 November 2014 – Keysight Technologies introduced 200-, 300- and 500-MHz, high-voltage probing solutions with a wider input range, higher common-mode rejection ratio and optimized accessories. The probes are ideal for testing today’s switching power supplies or power devices and for measuring motor drives and vehicle buses.
Oscilloscopes - Overview Products and Suppliers
The following list shows which oscilloscope manufacturer supplies which kind of instrument. The frequency in the header specifies the maximum bandwidth. In this list we considered only manufacturers offering scopes with a bandwidth of more than 100 MHz. In case of USB, PXI/PXIe, and LXI we regarded only instruments which are explicite specified as oscilloscope. There are many other instrumens available which are specified as digitizer oder data acquisition modules and might be suitable for some applications.
4 Channel 20 GHz Sampling Oscilloscope
22 October 2014 - With the new PicoScope 9341 20 GHz Sampling Oscilloscope, engineers can analyze two differential or four single-ended high-speed signals. The instrument is ideal for measuring skew and crosstalk between differential pairs on serial buses such as HDMI, SATA and PCIe, and for testing signal integrity at differential and single-ended transceiver ports. Data rates up to 40 Gb/s can be viewed, with 5th-harmonic characterization possible up to 8 Gb/s.
USB-connected Mixed-Signal Oscilloscopes
15 October 2014 - The new PicoScope 3000D Series Mixed-Signal Oscilloscopes (MSOs) form a complete portable test system, with two or four analog channels and sixteen digital channels as well as a built-in arbitrary waveform generator. The PicoScope 3000D Series MSOs are available with analog bandwidths from 60 MHz to 200 MHz. Maximum digital input frequency is 100 MHz, equivalent to a data rate of 200 Mb/s (5 ns pulse width) on each channel.
Teledyne LeCroy introduced new 1 GHz, 10 GS/s Oscilloscope
14 October 2014 - Teledyne LeCroy introduced the WaveSurfer 10 oscilloscope with 1 GHz and 10 GS/s at €9,990/£8,640. The WaveSurfer 10 combines the MAUI advanced user interface with powerful waveform processing, in addition to advanced math, measurement and debug tools, to quickly analyze and find the root cause of problems.

Oscilloscope History and Milestones
Oscilloscopes have been invented in the 1920s. Up to now this instrument encountered many innovations. In the beginning the most important manufacturers have been General Radio, DuMont, General Electric and Radio Corporation of America. Later Cossor and later Solartron dominated the market. Today the main players are Keysight, Tektronix and Teledyne LeCroy. Below we listed some important oscilloscope milestones.

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.
