The two new Tetris™ probes from Pico Technology offer high bandwidth in a compact and lightweight housing, and are ideal for testing densely-packed high-speed circuits. With their active circuitry, these probes deliver a significant performance improvement over passive probes.
While the input capacitance of a passive probe loads the signal source even at frequencies below 1 MHz, causing distortion, the Tetris probes maintain a high input impedance into the GHz range. This enables the accurate display of pulses with sub-nanosecond rise times. The Tetris probes are compatible with all standard high-bandwidth oscilloscopes with 50-ohm BNC inputs, such as the PicoScope 6000 Series.
The Tetris 1000 has a probe bandwidth of 1 GHz, while the Tetris 1500 is rated at 1.5 GHz. Other specifications are: input impedance 1 megohm in parallel with 0.9 pF; measuring range +/-8 V; attenuation 10:1 +/- 5%; cable length 1.3 m; weight (probe only) 96 g.
The probe heads have a T-shaped cross-section that allows them to be stacked side by side, closely enough to probe adjacent pins of a 0.1 inch IC package. The probes are supplied with a comprehensive accessory pack consisting of: low-inductance ground blade, assorted ground leads, L-In adapter, Z-Ground, 2 adhesive copper pads, two pico hooks, replacement solid and sprung tips, 0.8 mm socket adapter, and coloured cable markers. A universal mains power supply is also included.
The Tetris 1 GHz and 1.5 GHz probes are on sale now, priced at only £445 and £580. They are covered by our free two-year parts-and-labour warranty against manufacturing faults.
