Microwave Engineering Europe - November 2008 - (Page 41) PRODUCTS 41 Mixed-signal scope speeds acquisition offers long memory and fast waveform acquisition Yokogawa’s DLM2000 series is a family of mixed-signal oscilloscopes (MSOs) that provide up to 500 MHz bandwidth and 2 GS/s sampling speed. The scopes have a memory of up to 125 million points and an update rate up to 450,000 waveforms per second. The DLM2000 series includes histogram and trending functions, up to 20,000 history memories, digital filtering, zoom windows, user-defined mathematics and serial bus analysis. The series consists of six models: three with two channels and three with four, each covering the bandwidths 200, 350 and 500 MHz, respectively. Mixed-signal oscilloscope operation is enabled on the 4channel models by converting the fourth channel of analogue input to 8-bit logic, so that the instrument then functions as a 3-channel analogue plus 8-bit logic MSO. A high-resolution mode (up to 12-bit) is also available and the logic capability is complemented by the availability of new logic probes with individual bit threshold setting and 100 kOhm input impedance at 250 MHz. The instruments have a 8.4 inch (21.3 cm) high-resolution (XGA) display in a compact ‘portrait’ format package Modular DigRF V4 tester ready for future MIMO designs A Digital Radio Frequency (DigRF) V4 test solution from Agilent Technologies enables comprehensive stimulus and analysis for developers of radiofrequency integrated circuits (RF-IC) and baseband ICs (BBIC) as well as integrators of wireless handsets. It is suitable for development of LTE and WiMAX wireless devices and has a modular structure designed to accommodate future MIMO designs. DigRF V4, driven by the MIPI (Mobile Industry Processor Interface) Alliance, is a high-speed digital serial bus between mobile baseband and RF chips that is a key enabling technology for LTE and WiMAX. ‘Cross-domain’ test, such as DigRF V4, offers new insights that reach from individual digital bits all the way through to IQ-modulated RF signals. Agilent s test solution allows engineers to work in the domain (digital or RF) and abstraction level (physical or protocol layers) of their choice to characterize RF-ICs and rapidly solve cross-domain integration problems. The digital wireless test solution integrates DigRF V4 stimulus and protocol analysis tools into the company’s portfolio of digital, RF and wireless instruments. The Agilent RDX (Radio Digital Cross-Domain) tester consists of two new modules, the N5343A exerciser and the N5344A analysis module, which are housed in small, modular N2X mainframes. The Agilent E5345A and E5346A active probing solutions with capacitive loading of less than 0.15 pF and high sensitivity provide system insight with minimum disturbance at the gigabit speeds used in DigRF V4 testing. Design engineers can choose between the company’s new N5345A Midbus Probe with Soft Touch technology for fast probing on prototype boards, and B5346A flying leads probing solutions for space-constrained designs. This solution protects investment by supporting both DigRF V4 and V3 specifications. The test software environment includes protocol generation and analysis, and interoperates with the company’s Signal Studio software and 89600 vector signal analysis software. RF engineers save time by using familiar vector signal generation and analysis software, which supports the DigRF exerciser and analysis modules, as well as signal analyzers and signal sources. www.mwee.com/210800598 that occupies the size of a single A4 sheet of paper on the benchtop. The display is enhanced by a fine grid, high luminance and viewing angle, and on-screen markers with simultaneous display of cursors and automatic parameters. An option to provide up to 125 million points of storage capacity is available, allowing, for example, 10 kHz signals to be recorded for up to 5000 seconds. Even at a sampling rate of 1.25 GS/s, waveforms down to 0.1 s can be captured. With the history function, up to 20,000 previously captured waveforms can be saved in the acquisition memory, and any one or all of them can be displayed on screen with the ability to carry out cursor measurements and other analysis operations including FFT analysis and comprehensive user-defined maths. www.mwee.com/211300365 Wireless M-Bus RF module targets automatic meter reading and smart meter applications Radiocrafts AS has introduced a compact Wireless M-Bus RF module for use in automatic meter reading (AMR) and smart meter applications. The company claims the RC1180MBUS is the industry’s first compact all-embedded module compliant with the Wireless M-Bus standard, supporting two-way communication in S and T modes. It meets the Wireless M-Bus specification for all S1/2, T1/2 and R2 modes, and operates at 12 channels in the 868-MHz frequency band. The surface-mount RC1180-MBUS RF transceiver module measures 12.7 x 25.4 x 3.3 mm including shielding, replacing tens of components compared to a discrete design, said Radiocrafts. The module is easy to use with an UART interface for serial communication and configuration, and a onepin antenna connection. It supports two-way communication, enabling not only meter reading but also valve control and data acknowledgement. The M-Bus RF module is pre-certified for operation under the European radio regulations for license-free use. When used with quarterwave antennas, a line-of-sight range of 500-600 meter can be achieved. In addition, the module is designed for use in batteryoperated systems with up to 20 years of battery lifetime. www.mwee.com/211300056 Microwave Engineering ● November 2008 ● www.mwee.com http://www.mwee.com/211300365 http://www.mwee.com/210800598 http://www.mwee.com/211300056 http://www.mwee.com
