Real-time, Radiocommunication and 5G Measurements —DC to Terahertz Frequency Range

DC – 40 GHz. That’s the frequency in which Gauss Instruments’ TDEMI ULTRA is available—unless you want to extend it up to the Terahertz frequency range. Yes, that’s what external mixers can do for the TDEMI ULTRA—and for you.

TDEMI ULTRA and external mixers

The outstanding features and advantages of the largest real-time bandwidth in the T&M market, as well as the ability to perform ultra-fast measurements, are available throughout the frequency range through the use of external mixers. This means that TDEMI ULTRA applications are not limited to ultra-fast EMI measurements, but also include radio communication testing, especially the testing of signals and frequency bands and measurements for 5G applications.

Digital demodulation and emission measurement of an EUT in the range above 4GHz

The 685 MHz real-time bandwidth of the TDEMI ULTRA can display a fully gapless spectrogram with 300 ps POI, evaluate IQ data and perform digital demodulation. With this set-up 5G testing can be done in accordance with FCC standards. Compared with other 5G measurement solutions, the TDEMI ULTRA accelerates measurements tremendously. When combined with Gauss Instruments’ Automation Software Suite EM164k, additional novel evaluation tools and features are available, further simplifying daily testing work.

By using the TDEMI ULTRA’s unique real-time scanning feature, a measurement can be performed, displayed and recorded in the spectrogram mode over a range of several GHz in real time. By approaching the THz range, as well as with its real-time scanning capabilities, the TDEMI ULTRA opens the door to recording and visualization, exceeding current requirements for 5G testing and laying the foundation for the future.

The vast amount of recorded measurement data provides extraordinary characterization, documentation and evaluation possibilities. With the Automation Software Suite EMI64k, angle, radiation, height and polarization per frequency point can all be displayed.

In addition to their unrivaled technological advantages and range of applications, the TDEMI ULTRA and Automation Software Suite EMI64k provide significant economic benefits. By reducing overall test times and providing full EUT characterization, it’s possible to reduce testing and development costs, and to accelerate the time-to-market process of your products—all while increasing testing quality.

Gauss Instruments’ TDEMI family of EMI receivers provides an expansive, fully CISPR-compliant, real-time bandwidth that allows you to dramatically—and simultaneously— accelerate your measurements and reduce measurement uncertainty. By using Gauss Instruments’ full automation software suite EMI164k, test procedures can be configured in accordance with the CISPR 16-2-3 standard for FFT-based measuring instruments. Compared to previous pre-scan and final measurement strategies, this greatly increases overall test quality—and reduces test times by orders of magnitude.

Previously, pre-scan and final scan test procedures were performed to reduce overall test times. Today, Gauss Instruments’ offers a novel real-time scanning feature for the TDEMI X test receiver series that provides a real-time bandwidth spanning several Gigahertz, allowing final optimization to be performed at all frequencies—simultaneously, in just one step.

With a newly designed, very powerful hardware module, such measurements across several Gigahertz can be done in the real-time spectrum analyzer mode. In the 1-18 GHz frequency range all frequency points can be directly measured at a very high resolution in time and the results can be optimized instantly.

Over the entire frequency range the results are displayed in real time. Detectors’ peak, average and RMS are all available in this mode. What’s more, video bandwidths required in accordance with the standards can be applied. Of course, all measurements in accordance with the standards CISPR 16-1-1 MIL 461 and DO 160, as well as many other national and international standards, are fully covered.

EMI64 graphical user interface

For the first time, a typical measurement in the 1-18 GHz range can be scanned in real time by testing with Gauss Instruments’ TDEMI X receiver. The DUT is rotated in just one continuous movement and the angular position and the maximum level of emission are recorded. All requirements of CISPR 16-2-3, ANSI and FCC standards are met by the TDEMI X receiver.

Full 3D radiation pattern of the DUT

The upshot of all this is that EMC testing can now be more sustainable. For example, it is now possible to create an entire database and documentation with radiation patterns, test procedures and casing construction, as well as with much more information. Newly developed products and designs can be tested right from the beginning to make sure all required limits are met. This allows you to reduce the time and money you spend in the development, design and final market certification processes.

The EMI164k is not limited to CISPR applications. It also performs measurements in accordance with FCC and ANSI, or MIL-461 and DO-160 standards!

The TDEMI receiver family is ideal for all kinds of tests and applications, starting with pre-compliance, ultra-compact and mobile receivers right up to high-end EMI test solutions with up to 685 MHz real-time bandwidth and 40 GHz real-time scanning—all with the lowest noise floor available in the receiver and real-time analyzer market.

Thanks to the modular architecture of Gauss Instruments’ TDEMI EMI receivers, as well as the EMI164k automation software suite, ACA TMetrix can provide an optimized, cost-effective software solution tailored to your requirements.

ACA TMetrix is pleased to highlight two next-generation RF signal generators from Aim-TTi —the TGR2051 and TGR2053. Both units offer exceptional performance and improved functionality with touch screen operation.

The TGR2050 series of high-performance RF generators feature several enhancements, including:

• High frequency accuracy and stability;
• High signal purity with excellent phase noise;
• Output power levels of -127dBm to +13dBm;
• Flexible analog and digital modulation capabilities.

Doing development, test or service work? The TGR2500 series is ideal for all three.

TGR2050 series sweep function

The sweep function enables signals of varying frequency and/or amplitude to test a full range of input conditions quickly and efficiently. Step sweeps are created according to a formula over a specified number of points, in the range 2 – 1000. Formula specifics include: start and stop values and dwell time following SYNC at each point. Sweeps can be set to run in either direction, with linear or logarithmic spacing. Alternatively, list mode can be used to analyse the response at set frequencies and amplitude—dwelling on set values for specified amounts of time.

This is useful for testing at known problematic frequencies within a setup. The list can be created within the instrument or downloaded via the remote interfaces. The sweep setups can either be run through as a single sweep or in a continuous loop and prompted by an internal, external or manual trigger. Complex sweep triggering is available to control complete sweeps and/or each point within a sweep.

TGR-U01 option 

External digital modulation signals can be applied to the carrier waveform via the MOD in/out on the rear panel.

Advanced remote control accommodates sophisticated new automated systems and compatibility with Aim-TTI’s previous RF instruments enables incorporation into existing systems. With a small footprint and lightweight design, and the best price point / performance ratio in its class, the TGR2050 series maintains Aim-TTi’s reputation for high-quality, reliable, great-value products.
