Software Simplifies Evaluation of EM Measurements

Narda Safety Test Solutions of Germany now offers a remote control, analysis and management software package for the frequency-selective field measuring set SRM-3006. Called SRM-3006 TS, the PC software simplifies the acquisition and storage of the results of electromagnetic field measurements, enables subsequent analysis and the automatic generation of user-specific test reports.

Large quantities of data often result from electromagnetic radiation measurements designed to protect people or the environment. Data acquired by the Selective Radiation Meter SRM-3006 from Narda can now be managed, analysed and recorded using the SRM 3006 TS software .

All results can be subsequently analysed. For example, the software can automatically search for peak values in frequency spectra or determine average values over time periods. Integration over a selectable frequency range enables automatic determination of the field exposure due to an entire radio communication service, such as GSM-1800 downlink, or due to an individual service provider.

Instrument Grade Broadband Power Amplifiers

Giga-tronics microwave power amplifiers were designed in response to customer requests for higher power with very wide frequency range, flat frequency response and low noise. The amplifiers are easily used in R&D lab applications and manufacturing automated test systems to overcome power losses from a signal generator or whenever higher power is required. The small size and light weight make them ideal for Lab bench applications, while the ability to place the amplifier close to the device under test (DUT) minimizes cable loss for more optimal testing.

The Giga-tronics microwave power amplifiers are ideal companions to the Giga-tronics microwave signal generators. The amplifiers also feature high reverse isolation, excellent input and output match and the long life and reliability of solid-state technology. Delivery is 6 to 8 weeks ARO.
