ASIA-PACIFIC BROADCASTING

Wideband radar and wideband satellite communications signals use carrier frequencies that are beyond the direct synthesis and direct analysis capabilities of wideband RF instruments. In order to test radar and satellite devices using these instruments, engineers often build their own test fixtures and signal-conditioning capabilities. By using the new SenarioTek solution, engineers can instead take advantage of a calibrated and optimised solution for doing this testing using Tektronix RF test instruments such as the AWG7000 series signal generators and the DPO/DSA/MSO70000 series high-performance oscilloscopes.

The approach used by the SenarioTek solution improves microwave test perfor-mance by matching microwave up and down conversion from and to an intermediate frequency (IF). This optimises the performance of the Tektronix instruments and eliminates instabilities, cost and -periodic calibration of in-phase quadrature (IQ) modulator conversion techniques. It also provides the widest bandwidth signal generation and analysis, and can be used for both multi-band radar and satellite-communication frequencies.

“This SenarioTek offering represents a significant breakthrough in giving our customers a standard, yet highly cus-tomisable solution, for demanding wideband radar and satellite-test applications,” said Lynne Camp, vice-president of Performance Pro-ducts at Tektronix.

“This new direct IF solution is significant because it provides the widest combined signal generation and analysis bandwidths designed to optimise the highest fidelity in our instruments. The total solution is the most cost-effective method to analyse wideband microwave signals,” Camp concluded.
