Tektronix has introduced the MDO4000B series of mixed domain oscilloscopes that features enhanced spectrum analyser performance and when used with the company’s SignalVu-PC, a very wide bandwidth vector signal analysis capability with advanced support for WLAN 802.11 a/b/g/j/n/p/ac testing. 

These mixed domain oscilloscopes feature an integrated spectrum analyser that can capture time-correlated analogue, digital and RF signals for a complete system view of a user’s device.

Incorporating WLAN into designs introduces a whole new level of complexity that can be challenging to debug on a system level without the right tools,” said Fanny Mlinarsky, President and CTO of octoScope, a provider of wireless test solutions and services. “The MDO4000B with SignalVu-PC enable embedded and WLAN module designers to rapidly debug systems without a steep learning curve.”

The instruments combine the functionality of the company’s mixed signal oscilloscopes (MSO) with a powerful spectrum analyser in a single instrument. The new MDO4000B Tektronix has significantly enhanced the performance of the MDO’s spectrum analyser compared offers enhanced capabilities compared to previous generations including:  

•          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 20dB enabling 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.

The company claims that when used with its SignalVu-PC Vector Signal Analysis (VSA) software, the MDO4000B offers the one of the industry’s widest bandwidth (=1 GHz) vector signal analysers, 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.
