Tektronix MDO4000B Series mixed domain oscilloscope

Tektronix mixed domain oscilloscopes are said to be the only oscilloscopes with an integrated spectrum analyser that can capture time-correlated analog, digital and RF signals for a complete system view of a user’s device. The product’s vector-calibrated I&Q data enables high-accuracy modulation and vector measurements.

The series’ spurious-free dynamic range (SFDR) has improved to 60 dBc guaranteed and 65 dBc typical (from 55/60 typical), giving users confidence while performing spurious searches. Its phase-noise performance has also improved as much as 20 dB, enabling close-in spurious measurements and phase-noise evaluation.

The maximum RF acquisition time has been doubled from 79 to 158 ms, enabling longer time correlation with the rest of the system as well as the capture and analysis of multiple bursts of modulated data. The lower frequency limit has meanwhile dropped from 50 to 9 kHz, enabling EMI diagnostics over the frequency range specified by international regulations.

When used with the Tekronix SignalVu-PC, the product is said to achieve the industry’s widest bandwidth vector signal analysis capability and deep support for WLAN 802.11 a/b/g/j/n/p/ac testing.
