New 500 MHz Scope Probe and Accessories

To keep pace with the increasing bandwidth of our scopes, we have added three new high-frequency accessories to our product range this month:

  • 500 MHz 10:1 scope probe
    A passive high-impedance oscilloscope probe designed and calibrated for use on instruments having an input impedance of 1 MO shunted by 15 pF. It may be compensated for use with instruments having an input capacitance of 10 to 35 pF. The probe also has high-frequency compensation adjustment.
  • 50 Ω attenuator set
    The TA050 attenuator set consists of four coaxial attenuators, with ratios of 3 dB, 6 dB, 10 dB and 20 dB, designed for use with signals up to 1 GHz on 50-ohm lines. Each attenuator has a male and a female BNC connector.
  • 50 Ω feedthrough terminator
    The TA051 feedthrough attenuator is a coaxial terminator with BNC connectors. It is useful for connecting signals from 50-ohm sources into instruments with high-impedance inputs, such as oscilloscopes. Bandwidth is 1 GHz.

All of these items are available from our website.

Changes to This Newsletter

To make sure that you receive the Pico news that is relevant to you, from next month we will be producing two newsletters instead of one. These are the two new titles:

  • Pico Technology Test & Measurement Newsletter
  • Pico Technology Automotive Newsletter

At first you will automatically receive both newsletters. Each one will contain instructions in case you wish to cancel your subscription to one or both of them. If you do nothing, then you will continue to receive both newsletters.

Questions and Answers

Here is a selection of the questions that have cropped up recently on our help desk and our support forum.

Q. How do I change the frequency band on the PicoScope 6 spectrum analyzer?
A. First, make sure that you have the latest version, PicoScope 6.0.12, which has a greatly improved spectrum analyser. Now you should be able to use the zoom tools on the toolbar at the top of the window to zoom in and out on the frequency axis. For example, to zoom in, click the zoom-in tool button (a magnifying glass with a plus sign on the lens). The mouse pointer becomes a zoom-in tool. You can then click on the frequency axis where you want the band to start, drag to the point where you want it to stop, then release the mouse button. PicoScope will zoom in to show the frequency band you have selected without changing the vertical scaling.

Q. What is the difference between oversampling and Resolution Enhance?
A. Oversampling means capturing samples faster than the requested sampling rate, then averaging groups of samples to produce a smoothed set of samples. This is the noise reduction technique used in PicoScope 5. The drawback of this method is that the scope must be able to sample faster in order to generate the extra samples. Resolution Enhance uses a finite impulse response filter to smooth out the data, reducing the effect of noise at the expense of low-pass-filtering your signal. This is the method used in PicoScope 6.

Q. How can I get EnviroMon to display in Fahrenheit instead of Celsius?
A. There is an option to display units in either Fahrenheit or Celsius. Go the the Settings menu and select Configuration. Click the General button, then the Temperature button, and you will see the Units selection box that allows you to select your temperature units.

Pico Products in Action

There are many published examples of Pico products in use. Here are a couple of interesting ones that we have seen recently:

PicoScope 5 at the Open University. The Open University’s Interfaculty Electronics and Computing department has produced this educational video showing how to construct a crystal radio. They use a Pico oscilloscope to capture the audio waveform. The PicoScope software is ideal for this because it uses a PC to produce its high-resolution display, which then be easily captured in a video recording.

ADC-212 at scopeboy.com. Steve Conner describes how he used an ADC-212 to capture waveforms from his Tesla coil. As well as the impressive photographs, his report shows that even our older products are still being put to good use. Despite being overtaken by our newer USB scopes, the ADC-212 is still popular and is still supported by PicoScope 5. More power, Igor!

Automotive News

New product: S-hook

As a PicoScope user, you know that it can be difficult to keep all those test cables tidy in the engine bay. Well, we have come up with a small but indispensable accessory to make this task easier. The S-hook is about 100 mm (4 in) long and coated in plastic and rubber to protect the vehicle's paintwork and your cables. Hook one end underneath the bonnet or hood, and use the other end to hang a bundle of cables up to about 25 mm (1 in) thick.
