Tektronix launched its MDO4000B series, offering a wide bandwidth vector signal analyser for advanced analysis.
Tektronix introduced the MDO4000B series of mixed domain oscilloscopes that features significantly enhanced spectrum analyser performance and, when used with Tektronix SignalVu-PC, the industry’s widest bandwidth vector signal analysis capability and deep support for WLAN 802.11 a/b/g/j/n/p/ac testing.
At its core, a mixed domain oscilloscope combines the functionality of Tektronix popular mixed signal oscilloscopes (MSO) with a powerful spectrum analyser in a single instrument. With the introduction of the MDO4000B Tektronix has significantly enhanced the performance of the MDO’s spectrum analyser compared to the original MDO4000 instruments. These enhancements include the following:
Spurious Free Dynamic Range (SFDR) has improved to 60dBc guaranteed and 65dBc typical (from 55/60 typical) giving users higher confidence while performing spurious searches.
Phase noise performance has improved as much as 20dBenabling close-in spurious measurements and phase noise evaluation.
Vector calibrated I&Q data enable high-accuracy modulation and vector measurements.
Maximum RF acquisition time has been doubled from 79ms to 158ms enabling longer time correlation with the rest of the system as well as the capture and analysis of multiple bursts of modulated data.
Lower Frequency Limit has dropped from 50 kHz to 9 kHz enabling EMI diagnostics over the frequency range specified by international regulations.
When used with SignalVu-PC Vector Signal Analysis (VSA) software, the MDO4000B offers =1 GHz bandwidth, making this combination well-suited for such RF test and measurement tasks as general modulation analysis, pulse analysis, frequency and phase settling, radar and spectrum management.
