This is a brand-new course for AS/A2 level, starting in September 2000. This new web page provides specific support for the course. Over the next few weeks we will be listing activities and experiments from the course suitable for use with our products.
Pico oscilloscope and data logging products are ideal for the course, in fact PicoScope is described in the recommended apparatus list (SFT12) as 'A software / hardware combination that transforms your PC into a very effective storage oscilloscope. Available in a range of configurations; increasing speed being matched by increasing cost.'

Our recommended oscilloscope product is the ADC200/50. This is a dual channel PC based oscilloscope / spectrum analyser that easily meets the requirements for EMT 5 (oscilloscope) in the apparatus list which states that 'A PC based oscilloscope is to be preferred for new purchases.'
If you are on a very limited budget, consider also the ADC200/20, however this is not really fast enough for Activity 220P (Measuring the speed of light). Activity 70D (Speed of a Pulse on a Coaxial Cable) can be done with the ADC200/20 but works better with the ADC200/50. The higher speed ADC200/100 is also suitable, but does not offer significant advantages for this course. The numbers of oscilloscopes required will depend on class size, budget and availability of PC's. The course guidelines recommend 1 oscilloscope as a minimum, 4 to undertake the course with few compromises and 8 as ideal.

Our recommended data logging product is the DrDAQ. This is a low cost PC based data logger with built in sensors for light, temperature, sound level and sound waveform. It also has connectors for voltage, resistance and pH electrodes.
DrDAQ meets the requirements for MPU 2 (data capture device) and due to its built in sensors, it also meets most of the requirements of MPU 3 (range of sensors). The course recommends a minimum of 1 data logger and 8 as ideal. Due to the low cost (Under £60) it may make sense to buy as many DrDAQ data loggers as you have PCs available.

Light gates can also be used with the DrDAQ which can resolve to better than 0.001 sec. Suitable light gates can be purchased from Technology Supplies (Tel 01630 637300, part no 970-128). When using a pair of light gates, plug one into the voltage input and the other into the resistance input (which when driven from a low impedance will measure voltage). Using PicoScopes rulers (or automated measurements) time measurements can easily be made.
Our version of activity 110E Predicting the motion of a falling card shows the use of light gates with DrDAQ. The science experiment Measuring the speed of a model car shows how to make your own light gates.
