These high-speed oscilloscopes feature large, touch-screen displays, flexible triggering capabilities, and analog bandwidths to 4 GHz in compact, portable enclosures.
Digital storage oscilloscopes (DSOs) with analog bandwidths to 4 GHz are powerful measurement tools for analysis and troubleshooting. But include built-in logic and protocol analyzers, and the three new Infiniium 9000 series DSOs from Agilent Technologies become mixed-signal oscilloscopes (MSOs) that can handle a wide range of test challenges, including troubleshooting equipment with high-speed PCIe and Universal Serial Bus (USB) interfaces. All of the six new 8-b Infiniium 9000 series DSOs and MSOs provide four oscilloscope measurement channels with 20 GSamples/s maximum analog sampling capability across two channels and 10 GSamples/s capability across all four channels.
The new DSO models (see figure) are the 1-GHz DSO 9104A, the 2.5-GHz DSO 9254A, and the 4-GHz DSO 9404A. The new MSO models, which each provide 16 channels of logic analysis in addition to the four oscilloscope channels, are the 1-GHz MSO 9104A, the 2.5-GHz MSO 9254A, and the 4-GHz MSO 9404A. The oscilloscopes display results on a large 15-in. (38.1-cm) XGA liquid-crystal-display (LCD) touch screen.
The DSO and MSO models weigh less than 26 lbs and measure 13 x 17 x 9 in. They provide a main time base range of 50 ps/div to 20 s/div with 1-ps resolution and only 2 ns typical channel-to-channel skew. The horizontal position range can be adjusted by 0 to 200 s. For simplicity, a dedicated single acquisition button offers a quick way to capture a unique event. The 1-, 2.5-, and 4-GHz models represent10- to-90-percent rise/fall times of 400, 160, and 100 ps and 20-to-80-percent rise/fall times of 268, 107, and 67 ps, respectively. The instruments offer two measurement ports, with input impedance of 1 MOhms and 50 Ohms. The input sensitivity for the high-impedance port, which is AC and DC coupled, ranges from 1 mV/div to 5 V/div. The input sensitivity for the DC-coupled high-frequency port ranges from 1 mV/ div to 1 V/div.
The high-performance instruments offer DC gain accuracy of 2 percent of full scale at full resolution. The DSOs and MSOs boast a wide range of trigger modes, including edge trigger, edge transition, glitch trigger, line voltage trigger, and window trigger capabilities. They include trigger input/output ports to provide an easy way to synchronize scope to other instruments, built-in 10-MHz reference input and output port to synchronize multiple measurement instruments in a system, an XGA video output port, and standard USB and Ethernet LAN ports.
An upgrade kit is available to transform a DSO into an MSO. In addition, the instruments are available with a removable hard drive for secure installations. Along with the scopes, the firm also announced the availability of the Agilent N2870A series passive probes with bandwidths as wide as DC to 1.5 GHz for high-speed digital test applications.
