Portable EDS Tester Conforms Fully to Different Calibration RequirementsThe ESD3000 from HV Technologies is a lightweight, hand-held battery operated tester. Its modular construction enables testing to many different standards simply by changing the module. A broad range of accessories enables testing to many applications for contact discharge, air discharge, and indirect discharge. The interchangeable discharge modules (DM) quickly adapt to the ESD3000 to specified circuits of a new application. Each module fitted to this device is automatically identified, and the corresponding program is displayed. Modules can be configured to meet requirements to meet requirements for specific component values, and the correct wave shape can be achieved using the defined calibration method. The modules contain all the high voltage circuits needed to allow the ESD300 system to conform fully to different calibration requirements. Electronic polarity reversal, including alternation polarity, is provided as standard in all ESD3000 models.

The test system combines the Agilent PSA Series spectrum analyzer and the Agilent Infiniium oscilloscope along with the company’s 89601A vector signal analysis (VSA) software. The E4440A series PSA used as the down converters, producing input signals that range from 3.80 GHz to 50 GHz center frequency to an IF output frequency of 321.4 MHz. The IF signal is then applied to an Infiniium scope for digitization. The digitized data is then analyzed by the 89601A VSA that can reside on a separate PC or within the oscilloscope. Communication between the instruments and the 89601A software is accomplished using a LAN and a hub or switch. If the time bases must be tied together, the signal generator time base can be used as master.

The spectrum analyzers offer a phase noise of -110 dBC/Hz at 10 kHz offset (800 MHz typical). The devices include a GPIB interface. An available option suite allows the user to measure the RF of TD-SCDMA signals and the modulation quality of TD-SCDMA transmitters. The analyzer’s software provides multiple phase noise trace plots on the same scale in different colors with user-created limit lines to predict system EVM and BER. These analyzers support GSM, CDMA, W-CDMA/HSDPA, EVDO, and WiMax measurements. Find more information on the Anritsu website. Power Density Meter Measures RF Field Strength The power density meter from Laplace Instruments measures the RF field strength over the range of 0.001 to 2000 µW/cm2. This sensitive meter can accurately measure the RF background level even in rural areas. The meter reads true power density directly on the display with three ranges: 20, 200, and 2000 µW/cm2. At FM, TV, and mobile phone frequencies, accuracy is better than 3 dB. This device has a built-in antenna and detection system that yields a flat response over a very wide range of frequencies. Even a 5 GHz, signals can be measured. Wide bandwidth is 0.5 MHz – 3 GHz, and narrow bandwidth is 100 MHz to 3 GHz.For more product information, go to the Laplace website.

Microwave Signal Generator Offers Improved Phase NoiseThe R&S®SMF 100-A microwave signal generators from Rohde & Schwarz are now available with improved close-in phase noise—an option crucial in today’s microwave and R&D markets for obtaining reliable results when testing receivers and transmitters. This new R&S®SMF option further enhances the SSB phase noise for small offsets from the carrier. The R&S®SMF-B22 option can be installed in an R&S®SMF100A microwave signal generator along with one of the R&S®SMF-B122 (22 GHz) or R&S®SMF-B144 (43.5 GHz) frequency options. Two applications demonstrate the benefits of the R&S®SMF-B22 option. Doppler radars need excellent close-in phase noise because of the slow velocity of the target. Secondly, when frequency multiplication is used to achieve the required output frequency, the phase noise of the output signal increases by 20 log (multiplication factor).View the official announcement on the R&S website.
