Tektronix addresses RF/Microwave challenges, hosts Mesuro at IMS booth
-- Test & Measurement World, 6/14/2009 4:57:00 PM
Tektronix featured a range of new and enhanced products at IMS 2009, addressing radio communications, spectrum management, radar, electronic warfare, amplifier device characterization, and ultra-wideband applications. It partnered with Mesuro on nonlinear measurements.
Among products the company highlighted was the recently introduced Option 200 for the RSA6000 Series spectrum analyzer, which operates to 14 GHz and which incorporates DPX Density triggering to enable the isolation of frequency domain signals based on the statistical occurrence. With more than 292,000 spectrum updates per second, the patented DPX technology represents a six-fold improvement on the company’s first generation DPX capability. Also included in Option 200 on the RSA6000 Series spectrum analyzers are time-qualified and runt triggering functionalities that bring complex time-domain oscilloscope triggering functionality to the spectrum analyzer.
Driving the greening of wireless with open-loop active harmonic load pull
In addition, at its IMS 2009 booth, Tektronix teamed with Mesuro to demonstrate a system for nonlinear measurements. (See related article, "
Mesuro launches commercial active load-pull system
.") Based on the Tektronix AWG7122B arbitrary waveform generator and DSA8200 sampling oscilloscope, the Mesuro MB 20 open loop active harmonic load pull system enables the characterization of devices and power amplifiers for any signal and impedance environment up to 150 W. Being an all-electronic solution, it is suitable for on-wafer measurements. Such systems enable customers to design more efficient power devices for the wireless industry and have a demonstrated capability to optimize performance with first-pass designs.
Arbitrary waveform generators simplify S-parameter measurements
Tektronix also highlighted a new software module for RFXpress (RFX100 option SPARA) that provides emulation of RF components from Touchstone files. Engineers can use arbitrary waveform signals and cascade multiple Touchstone files to emulate an RF chain to gain insight into component behavior with a complex stimulus and to shorten design time. The effect of the RF component can also be de-embedded by selecting the Inversion option. This option also adds a provision to characterize a two-port device (DUT). A wizard simplifies the process by guiding you through a step-by-step process to obtain S21 characteristics (Insertion loss) of the device in a text format.
Government communications applications
The company also highlighted the RSA6000 Series spectrum analyzer with option 21, which now includes new modulation analysis and display enhancements for the government communications designer and operators of spectrum management systems. The new modulation types enable development of cutting-edge communications systems necessary to meet the need for increased communications bandwidth and spectrum efficiency in military and homeland security applications. These enhancements are a free software upgrade to existing RSA6000 Series owners.
H600/SA2600 products enhanced for remote monitoring applications
Tektronix also highlighted spectrum analyzers for interference and signal hunting applications, touting new enhancements that improve their utility for remote RF monitoring and sensing applications. Users are able to improve spectrum awareness for unattended applications with synchronous triggering and GPS time stamps for RF measurements.
