Sniffer hunts out handset current drain

The R and S Current Sniffer is ideal for a wide range of applications, and is a valuable tool for optimising power-saving routines.

Intelligent current management for mobile phones is a topic that interests manufacturers of user equipment, network operators and service technicians alike.

By using the R and S Current Sniffer, a current source can be simulated and the exact amount of energy thus absorbed can be determined.

The mobile phone is subjected to different load conditions to measure and evaluate current drain at high time and amplitude resolution.

The data thus obtained helps to assess whether the battery is being unnecessarily or erroneously discharged, for example.

Rohde and Schwarz provides a compact solution that allows exact error analysis not only for mobile phones but for all other portable equipment as well.

Mobile phone customers expect not only stability and reliability in new applications such as video streaming, web browsing or TV.

They also expect the development of new applications to include intelligent planning of power consumption in order to prevent any interruptions in the flow of information.

The R and S Current Sniffer combines the R and S NGMO2 dual-channel analyser/power supply with R and S NGMO2-K10 operating software.

The solution from Rohde and Schwarz is outstanding because of its combination of long observation times and high time resolution.

This combination makes the R and S Current Sniffer particularly valuable when it comes to specifying the current drain.

The R and S Current Sniffer is thus ideal for a wide range of applications, and is a valuable tool for optimising power-saving routines.

Handset developers can use the R and S Current Sniffer to help optimise the current drain of applications, preventing unnecessary or faulty battery discharge.

If a specific level of current drain is not exceeded in a practical application, the operating time of the mobile phone can be reliably assessed.

By using the R and S Current Sniffer, network operators can check the UE manufacturers' statements on operating time.

By means of parameterisation, they can also exert influence on the battery operating times of the mobile phones by optimising the discontinuous transmission mode (DTx) parameters used.

The R and S Current Sniffer provides the necessary information via current transient analysis.

Servicing also becomes easier: by accurately analysing the current drain, the R and S Current Sniffer helps mobile phone manufacturers to assess whether errors occur in an application while running.

It is not necessary to open the mobile phone to see which modules are active at a specific point in time.

Service technicians can now access the databases of various manufacturers to diagnose errors by means of the current-related data.

The R and S Current Sniffer is now available from Rohde and Schwarz.
