Picoscope 2205a. This range of PicoScopes are extremely versatile, with an Oscilloscope, spectrum analyser and arbitrary waveform generator in each model. Their compact size makes them extremely portable and the cases are very robust. Connections are simple, comprising, channel A, channel B, signal out and USB socket. Dimensions (L W H): 100 135 45mm.The USB (2.0) provides power, eliminating the need for an external power supply. The USB connection facilitates high speed data transmission.The Windows software supplied with each PicoScope is very simple to use. It features an auto setup function which reduces setup time to few minutes. Updates to the software are provided free of charge.Both models have input ranges of: ±50 mV, ±100 mV, ±500 mV, ±1 V, ±2 V, ±5 V, ±10 ±20 V.Specification:Model: Picoscope 2204• Bandwith (MHz): 10• ETS (GS/s): 5.0• Sampling rate (MS/s): 100• Scale (ns-s/div): 2-50Model: Picoscope 2205• Bandwith (MHz): 20• ETS (GS/s): 10.0• Sampling rate (MS/s): 200• Scale (ns-s/div): 1-50Signal Generator Output:• Buffer Size: 4k words• Vertical Resolution: bits• Output Range: ±125 mV to ±2 pk-pk with ±1 offset• Output Resistance: 600 Ω• Clock Frequency: MHz• Bandwidth: DC to MHz
