New PicoSource Pulse Generators!


The new PicoSource PG900 Series differential pulse generators can stimulate a transmission path, device or network with a broad-spectrum signal in a single instant. These signals are invaluable for making high-speed broadband measurements in many fields such as time-domain reflectometry, semiconductor testing, gigabit interconnect and port testing, and in radar systems.

Despite the dominance of high-speed differential data in today's digital, computing, interconnect and telecommunications systems, it was hard to find cost-effective, fast-transition differential pulse generators... until now!

Highlights of the new PicoSource PG900 Series differential pulse generators:

  • 60 ps edge step recovery diode outputs, amplitude adjustable up to 6 V (PG911)
  • 40 ps edge tunnel diode outputs, fixed > 200 mV amplitude (PG912)
  • Dual-technology model (PG914) with both types of output
  • Differential outputs with programmable deskew in 1 ps steps
  • Signal characteristics specified in detail
  • USB-connected
  • Graphical control software (for Microsoft Windows) included

PicoScope 9000 Series sampling oscilloscopes latest


The PicoScope 9000 Series sampling oscilloscopes are specialized USB-connected measuring instruments for viewing high-speed, repetitive signals such as serial data streams and test patterns. They are available with bandwidths of 12 GHz and 20 GHz, and with optional TDR (time-domain reflectometry), TDT (time-domain transmissometry) and optical-input capabilities.

Updated Programmer's Guide

For those developing custom applications for the PicoScope 9300 Series sampling oscilloscopes, an updated PicoScope 9300 Series Programmer's Guide is now available. This includes new instructions on programming the oscilloscopes in TDR (time-domain reflectometry) and TDT (time-domain transmissometry) applications as well as measurement of optical parameters. These sampling oscilloscopes can be controlled from a PC through either the USB or Ethernet port to provide all the functions available in the PicoSample 3 software, including:

  • Time-domain display and characterization of repetitive signals up to 20 GHz bandwidth
  • Multiple math functions of input channels
  • Eye pattern analysis
  • Automated amplitude and timing measurements to IEEE 1057–2007
  • Measurement of optical parameters (with the PicoScope 9321 optical-input model)

Differential TDR probing challenge solved

Pico Technology now recommends the GigaProbes DVT30-1MM Dual Probe TDR Interconnect Analysis Kit for use with the PicoScope 9000 Series. The DVT30 is a 30 GHz balanced odd-mode 100 Ω differential time-domain reflectometry (TDR) probe, featuring conductive diamond-tipped contacts that can make a reliable connection to differential striplines and device pads on PCBs. It is thus ideal for making accurate measurements of signal levels and impedances on high-speed differential data lines. The DVT30-1MM can also be used on 50 Ω single-ended circuits using the adaptors included in the kit. [2009-08]

New range of mixed-signal PicoScopes


The new PicoScope 3000D Series Mixed-Signal Oscilloscopes (MSOs) are ideal for engineers working on a diverse range of embedded systems. These compact USB-connected devices 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.

“We have completely redesigned the PicoScope 3000 Series MSOs,” explained Managing Director Alan Tong. “The key specifications—sampling rate, buffer size and display update rate—have all been improved, while we’ve retained the benefit of USB-powering that makes PicoScopes so much more convenient and portable than their traditional benchtop equivalents.”

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. All models come with a USB 3.0 interface and are fully compatible with USB 2.0, giving high performance and fast update rates with both port types. [2014-09]

A PicoScope with eight high-resolution channels


The new 8-channel PC oscilloscope from Pico Technology offers the perfect solution for advanced multi-channel applications. Housed in a compact and rugged enclosure, the PicoScope 4824 features 12-bit resolution, SuperSpeed USB 3.0 interface, and an integrated 14-bit arbitrary waveform generator (AWG).

Managing Director Alan Tong explains “The new 8-channel PicoScope has the same small footprint as Pico’s existing 2 and 4-channel models, and can replace the cumbersome full-sized scope on your workbench”. Like all PicoScopes, the 4824 is small, light, and highly portable; despite its high specification it is entirely powered via USB and does not require a bulky separate adaptor. [2014-09]

Tech Tip: DrDAQ as pH alarm


Q. I want to use the output from the pH probe on the DrDAQ to turn a pump on when the pH exceeds a set value. Is there software available or some info on using the output pins to control a solid-state relay?

A. Yes, you can do this using the PicoLog application supplied with your DrDAQ. The Edit channel > Parameter options dialog has an Alarm button: click this, enable the alarm, set the lower and upper thresholds, and PicoLog will activate an alarm sound when the pH goes out of range. Now check one of the relevant Digital Output boxes to make PicoLog activate the desired output at the same time as the sound. The outputs are nominally 0 volts low, 3.3 volts high, with 2.2 kΩ source impedance, suitable for driving an NPN transistor or a solid-state relay. 01-2016

Focus on: 1-Wire serial protocol decoding


The serial decoding feature in PicoScope 6.11 can decode 17 protocols including RS-232/UART, CAN bus, SPI and I²C. Serial decoding is included as standard, at no extra charge, with every copy of PicoScope 6. This month we focus on one of the recently added protocols: 1-Wire.

1-Wire is a serial communications bus system developed by Dallas Semiconductor Corp. (now Maxim Integrated Products, Inc.) It provides low-speed data, signaling and power over a single line. 1-Wire is similar in concept to I²C, but with lower data rates and longer range.

1-Wire bus topologyA typical network consists of a single master device connected to one or more slaves. Communication is bidirectional half-duplex, bit-sequential, with the LSB transmitted first. Speeds of 16 kbps standard mode and 142 kbps overdrive mode are supported. The master device can interrogate the network to discover what slave devices are connected and obtain their IDs. In most devices, power is derived from an internal power storage capacitor that stores charge when the 1-Wire line is in the idle high state.

PicoScope can decode as many 1-Wire signals as you have inputs on your oscilloscope, or even a mixture of serial protocols at the same time. Its serial decoding table lists detailed properties for each data packet: start and end time, reset and presence pulse durations, command code, command and data. Optionally it can also show voltage and duration statistics. The selected packet is highlighted in both graphical and table views for easy cross-referencing. You can filter and search the data, and export the decoded data to spreadsheet or text files.

Tech Tip: Zero Offset function in PicoScope 6


Ever wished you could null out the voltage offset on your scope or an attached probe? PicoScope 6 now includes this function as part of its Channel Options menu. Click the channel name (such as A) on the toolbar to see this menu, which has a Zero Offset section. After you click Zero you will be asked to remove any probe from the input channel and short-circuit the input to eliminate stray voltages. PicoScope will then perform the adjustment automatically.

Zero Offset is available on all PicoScope oscilloscopes and is handled digitally. A related feature called DC Offset, which operates on the analog signal, is available on PicoScopes with the necessary hardware. It allows you to apply an arbitrary offset voltage to avoid saturating the input. See your PicoScope 6 User's Guide for a list of devices that include this feature. [2015-12]

Focus on: SENT serial protocol decoding


The serial decoding feature in PicoScope 6 can decode 17 protocols including RS-232/UART, CAN bus, SPI and I²C. Serial decoding is included as standard, at no extra charge, with every copy of PicoScope 6. This month we focus on one of the recently added automotive protocols, SENT.

Background – SENT (Single Edge Nibble Transmission) is a serial interface originally designed for automotive applications. Lower in cost than other serial protocols, SENT has become popular in high-resolution sensor applications such as throttle position, pressure, mass airflow and temperature.

Data is normally transmitted as two 12-bit data words in a message frame. Data is transmitted as nibbles – 4 bits of data encoded in the timing of successive falling edges.

SENT decodingSENT decoding with PicoScope – The first step is to acquire the SENT signal using PicoScope. Then select Serial Decoding from the Tools menu and set up a new SENT decoder. The decoder will show the decoded SENT messages in the PicoScope scope view alongside the analog signal. PicoScope can also display SENT data in a table. Double-click a message in the table to highlight the same message in the scope view.
