More Tests in Less Time

The BI200/BI201 are ultra high performance time and frequency measurement instruments. Their high resolution and throughput, combined with continuous measurement capability, allow you to make measurements that are not possible with traditional time-interval counters. For example, they can timetag events (edges of an input pulse train) at a rate of 4 million per second continuously to on-board memory, while each of the edges is measured with 3ps resolution. This provides the instruments with the capability to analyze the dynamic variations in pulse timing, pulsewidth, or frequency. In other words, the difference between the BI200/BI201 and traditional counter/timers is analogous to the difference between voltmeters and scopes. Measurements can also be streamed continuously over the PCI Express interface allowing unlimited acquisition at high rates.

Full-Featured Instruments

The BI200/BI201 are full instruments-on-a-card with all the features and capabilities you would expect in a bench-top instrument including high quality inputs, built-in NIST traceable calibration, and software and hardware that deliver fully computed results. The instruments have 10 measurement functions such as Frequency, Time Interval and Pulsewidth. All functions work directly on the input signal at frequencies up to 2GHz (4Gb/s) for the BI200 or 800MHz (1.6Gb/s) for the BI201 without any prescaling. This means that you can measure pulses as narrow as 100ps, occurring at frequencies up to 2GHz, or the skew between two signals at 4Gb/s.

The inputs of the instruments include programmable termination voltage and hysteresis. These are features that are seldom found even in the best of the bench-top instruments. When you connect your signal source to the BI200/BI201 it sees a 50 ohm load which is terminated to an accurately programmable voltage between -2V and +3V. This allows you to connect ECL, PECL, or CML sources directly to the instruments with the proper loading. It even allows you to terminate the signal from CMOS sources to a center voltage which provides a symmetrical load for superior performance. The programmable hysteresis is an important feature for signals with slow risetime or high noise levels. It sets different threshold levels for the rising edge and the falling edge which prevents false triggering.
