A 12-GHz PC-based oscilloscope
-- Test & Measurement World, 6/1/2008
The PicoScope 9201 is a two-channel sampling oscilloscope that connects to a PC through a USB port (Ethernet optional). With its 12-GHz bandwidth, the 9201 lets you measure eye diagrams on high-speed serial buses. Waveform analysis includes color-coded persistence. In addition, the instrument produces histograms in either the vertical or horizontal axis so you can measure the distribution of a signal’s edge timing or amplitude. You can make eye-diagram measurements and run mask tests on SONET and SDH signals for both return-to-zero (RZ) and non-return-to-zero (NRZ) signals.
In addition to 12-GHz bandwidth, the PicoScope 9201 has 16 bits of vertical resolution. Its scale factors range from 20 mV/div to 255 mV/div. Measurement tools include cursors, channel math (up to four calculated waveforms on the screen at one time), and fast Fourier transforms with a choice of windowing functions. The PicoScope 9201 includes oscilloscope software that runs on Windows XP or Vista (32-bit versions).
