VectorStar offers the smallest, lightest and easiest-to-position frequency extension modules that connect directly to wafer probes. DifferentialView enhances accuracy with TMS measurements—giving engineers greater confidence to achieve higher product specifications through testing.
ESR EMI Test Receiver, Rohde & Schwarz
The R&S ESR26 EMI test receiver covers the frequency range from 10Hz to 26.5GHz and performs conducted or radiated certification measurements in line with EN, CISPR, FCC, and military standards. Its broadband architecture lets the ESR26 perform standard-compliant disturbance measurements. EMI measurements that took hours in the past can now be completed in just seconds, saving valuable time. In addition, the instrument offers comprehensive diagnostic tools. The persistence mode lets users to clearly differentiate between pulse and continuous disturbances.
The ESR26 displays the probability of amplitudes occurring at specific frequencies using different colors, making it possible to detect disturbances that are hidden by broadband signals. The frequency-mask trigger responds to specific events within a disturbance spectrum. If the mask is violated, a trigger is activated, the measurement stopped, and the user can analyze the disturbance and its effect. Users can also verify existing results by means of the conventional stepped frequency scan. Plus, the instrument is a full-featured spectrum analyzer, providing analysis tools such as IF analysis and time-domain display. A number of options make the R&S ESR26 ideal for field use. These include a DC power supply with rechargeable battery pack, a solid state drive, and an optional ruggedized housing.
SMW200A Vector Signal Generator, Rohde & Schwarz

AWG70000 Arbitrary Waveform Generator, Tektronix
As data rates and signal complexity increase across all electronics and RF segments, engineers and researchers need more advanced signal generators to stress new designs or to perform cutting-edge research. The ability to create, generate, or replicate either ideal, distorted, or "real-life" signals is essential in design, testing and operations of some of the world’s most complex data communications systems. The AWG70000A Series meets this need with an industry-leading combination of 50GS/s sample rate performance, 16GS of waveform memory and 10-bit vertical resolution. It produces fast, clean signals that can be routed through a receiver or other device under test for long periods of time for truly comprehensive testing.
Sample rate, dynamic range and waveform memory are key parameters for any AWG, and the AWG70000 excels at all three. The sample rate and waveform memory are unmatched by any AWG. High dynamic range is something that is normally only found in low sample rate AWG's, however, the AWG70000 provides as much as 80dBc of dynamic range. The AWG70000 Series helps accelerates designs and aid experimental research by enabling generation of advanced, previously impossible to generate, waveforms. By offering easy generation of very complex signals with complete control over signal characteristics, the AWG70000 offers an industry best solution for measurement challenges in the following applications—Defense Electronics, Optical, High-Speed Serial Data, and Advanced Research (see press release for specifics on each application area).
