Digitiser for advanced applications

31 July 2019 Test & Measurement

Tektronix, Inc. has unveiled the 6 Series low-profile digitiser, a 4-channel instrument offering up to 8 GHz bandwidth, 25 GSps sampling rate and a 12-bit ADC (analog-to-digital converter) on every channel, in a space-saving 2U rack form factor.

In contrast to digitisers that interleave sample rate, bandwidth and record length, the 6 Series delivers the same performance across all channels, making it ideal for advanced applications such as high-energy physics, weapons and materials research as well as automated test equipment (ATE) applications in technologies such as 5G mmWave, ultra wideband, WiGig and automotive radar.

In each of these applications, engineers require digitisers with the highest precision and performance possible coupled with a compact footprint for increased channel density. In the case of high-energy physics research, physicists, engineers and technicians often invest weeks to orchestrate ‘single-shot’ events and need confidence that the test results captured by digitisers are valid. The 6 Series digitiser delivers that confidence regardless of the number of input channels, which can number in the hundreds for large projects.

The digitiser uses the same Tektronix-designed 12-bit Tek049 ASIC on each of its four channels as the 5 and 6 Series mixed-signal oscilloscopes. It is available in multiple bandwidth options ranging from 1 GHz to 8 GHz and offers a 25 GSps sample rate with enhanced low-noise performance and a highly effective number of bits.

With patented ADC and digital down conversion (DDC) signal paths, users can acquire 2 GHz of RF capture bandwidth in Spectrum View while independently controlling the frequency and time domains. To maintain better accuracy over long periods of time, the digitiser can run signal path compensation without the need to remove cables or signals.
