 Advantest Corporation presents three new options for its U3700 spectrum analyzer series. The 2-channel input, time-based analysis and 6 GHz tracking generator options are now available at Rohde & Schwarz in Germany. All three options facilitate signal evaluation on production lines for wireless communications equipment and modules, thus saving the user valuable time and money. But the options can also be used for wireless network site surveys and other field uses.
Wireless communications are being used in an increasingly wide range of applications, including even game consoles and in-car electronics. At the same time, the volumes of data handled are constantly increasing. New communications technologies such as the multiple input, multiple output (MIMO) multiantenna technology help ensure a stable and high-speed transfer of data.
Advantest's new options for the U3700 spectrum analyzer offer an efficient evaluation system to measure the signal characteristics and so assess the quality of communications products.
The world’s first 2-channel input option adds two independently operating RF signal ports to the U3700, meaning that the operating parameters of different communications system standards can be measured in parallel, as can the output signals of two antennas. Moreover, the option enables two signals to be monitored in tandem with only one system which is not possible with 1-channel models and, to date, required a complex system constructed of two spectrum analyzers. This option now simplifies the measurement process and saves time. The frequency range is from 9 kHz to 3 GHz, the crosstalk between input channels is <-90 dBc.
The time-based analysis option can be used in assessing the performance of electronic devices that use digital modulation. This includes game consoles with wireless connectivity and in-car electronics as well as their components. By performing not only signal frequency analysis but also time-based signal analysis, the process of sorting good products from bad is greatly facilitated. Before, time-based analysis of variations in frequency, power, and phase required the spectrum analyzer to be used in conjunction with an oscilloscope, as well as complex computations. This new option now enables efficient and low-cost analysis in the frequency range up to 43 GHz using just one spectrum analyzer.
The frequency bandwidth of ETC and wireless LAN in accordance with the IEEE802.11 standards exceeds 5 GHz. Due to the new 6 GHz tracking generator option, users can now test and evaluate such wireless communications systems above 5 GHz using the favorably priced U3700 analyzer series. A new VSWR bridge up to 6 GHz with SMA connectors is now available to perform matching measurements.
The new 2-channel input, time-based analysis and 6 GHz tracking generator options for the U3700 spectrum analyzer series from Advantest are now available at Rohde & Schwarz.

The term/concept of synergy seems very apt when applied to the
interaction of the Occam process solderless assembly concept in
combination with a unique PCB interconnection technology called twisted
wire interconnect or TWI. 
Fortunately even the most conservative most prognosticators now see at least a subdued “recovery” in 2010.
