Saelig (www.saelig.com) has introduced Pico Technology’s (www.picotech.com) PS4227 Oscilloscope, which offers a real-time sampling rate of 250 MSa/s.

This 100 MHz two-channel USB scope is ideal for general, field-service and scientific use. For repetitive signals in vibration, noise and mechanical analysis, the scope’s 12-bit resolution mode can be adjusted to achieve enhanced resolution mode of up to 16 bits.

The scope, which is powered via a PC’s USB port, comes with an integrated function generator, spectrum analyzer and arbitrary waveform generator. With PS4227’s bandwidth of 100 MHz and two 12-bit input channels, waveforms can be easily captured for scientific analysis, production testing, debug tasks and electronic design. The scope’s third input is used as an external trigger, while an output signal generator is provided via a fourth BNC connector. The signal source enables users to create arbitrary test signal, use one of the scope’s six preset waveform types or utilize graphical editor to draw waveform signals.

Its 32 Megasample buffer memory and sample rates of up to 250 MS/s allows the use of the scope’s maximum sample rate despite slow time-bases. The scope’s buffer memory can support up to 10,000 waveforms, which are viewable in pop-up navigator window.

The scope, offered at a price of $1,479, also offers various other functions provided by PicoScope oscilloscope software, such as alarms, mask limit testing, math channels, serial data decoding, programmable low-pass filtering, reference waveforms, Digital Color and Analog Persistence display modes and XY mode. Its trigger selections include window, pulse width, dropout, interval and runt pulse.
