High-performance 8-bit flash microcontroller extends migratable memory flexibility

26 Jan 2000 DSP, Micros & Memory

Wavetek recently introduced three new instruments, Models 901, 901R and 900 which it claims surpass the performance of current counters on the market.

The Model 901 represents the state-of-the-art timer/counter measurements like time interval, frequency, phase and jitter. With an ultra-high time interval resolution of 50 ps single-shot and 1 ps averaged, plus a speed of up to 8000 measurements/s, the Model 901 is a high performer. Frequency range can be extended from 300 MHz to 2,7 GHz. In addition to being the market's most powerful timer/counter, when connected to a PC the 901 performs modulation domain analyser functions comparable to current state-of-the-art modulation domain analysers, says Wavetek.

The Model 901R is equipped with an atomic rubidium timebase frequency reference. It features outstanding accuracy when used for frequency calibration with uncertainty of 0,0001 ppm. The Model 900 is identical to Model 901 except for a 250 ps single-shot time interval resolution, 225 MHz basic frequency range and a speed of 2000 measurements.

The 901 has a high measurement rate of up to 8K measurements/s to internal memory (2K for Model 900) and up to 250 readings/s (125 for Model 900) for individually triggered measurements, one by one over the GPIB. Complex measurement set-ups can be stored in the instrument and instantly recalled for ultra-fast reprogramming of measure-ments. Compatibility with SCPI standard makes it easy to upgrade test system hardware without rewriting time-consuming software.

The 901 and 901R have built-in measurement time stamping and other hardware features for fast data capture. They are converted into modulation domain analysers when connected to a PC running TimeView software package to perform time and frequency analysis and advanced statistical and FFT-processing. TimeView also allows Model 901 to document frequency stability of generators/synthesizers over time.

An additional capability of the 901 is continuous 'back-to-back' period measurements on signals with repetition rates up to 40 kHz. This enables measurements on each and every input cycle without missing one single event. The warm up time of the 901R is very short. This makes the 901R ideal for providing accurate on-site calibration when transporting between numerous work locations.

A built-in statistical function captures data and calculate max, min, mean and standard deviation (RMS jitter) of 500 measurements in just 1 s. Sample sizes up to 1 million can be selected. The built-in mathematics function enables calculations like offset, drift, linearity, scaling and inversion.
