Fast oscilloscopes

Tektronix has introduced two new members of its TDS6000 family of digital storage oscilloscopes – the 12 GHz TDS6124C and the 15 GHz TDS6154C.

Tektronix has introduced two new members of its TDS6000 family of digital storage oscilloscopes (DSO) – the TDS6124C and the TDS6154C – along with the P7313 Z-Active low-loading probe.

The TDS6124C provides 12 GHz true analog bandwidth and user-selectable DSP for channel-to-channel and unit-to-unit matching. The TDS6154C also includes user-selectable DSP for channel-to-channel and unit-to-unit matching plus bandwidth extension to 15 GHz.

DSP adjusts the response throughout the bandwidth of the scope to accurately reflect magnitude and corrects phase response to make it linear. The TDS6154C is able to measure rise/fall times of 30 ps (typical) with accuracy to within five percent (20/80 percent rise time).

Both the TDS6124C and TDS6154C provide 40 GS/s sample rate on two channels simultaneously and up to 64M optional record length on two channels (2M on four channels standard). This equates to a time window of 1.6 ms at full bandwidth and a 25 ps sample interval. The TDS6000C family provides a random jitter noise floor of 420 fs rms (typical) for critical jitter measurements.

A Pinpoint Trigger System provides glitch/width triggering down to 100 ps and advanced serial pattern triggering up to 3.125 Gb/s in the TDS6124C and TDS6154C. In addition, a new option provides oscilloscope 8b/10b protocol triggering and decoding with which designers can trigger on four consecutive 10b symbols or defined errors. This means that incoming data can be triggered on in real-time without post processing, enabling designers to actually trigger on a fault rather than just hoping to find it through repeated searches.

The SiGe Z-active probing architecture of the new P7313 offers high speed (>12.5 true bandwidth, typical), high DC impedance, fast rise time (25 ps 20/80 percent), and the stable high frequency loading of Z0 probes to provide high bandwidth, flat frequency response, low-loading, and low noise differential for high-speed circuit designers.
