R&S®RT-ZVCA Multi-Channel Power Probe

• 5 Msample/s sampling rate for voltage and current
• 18-bit resolution for voltage and current, 32-bit for power
• Internal multiplier for power with full sampling rate of 5Msample/s
• Capable of running a measurement and logging the data for days
• Autoranging

The R&S®CMW combined with the R&S®CMWrun sequencer gives users a powerful setup to optimize the power consumption of their devices.

Predefined setting and the controlled environment of the R&S®CMW500 allow users to determine the exact power consumption behavior of their devices. They can simultaneously observe up to four different measurement points to determine which IP or signaling events are increasing/decreasing power consumption. Everything is consolidated into one report.

The R&S®CMWrun automation tool can estimate the battery life of a device. The software is capable of calculating integrated values over time. Our solution can estimate when the battery will be fully drained based on the battery capacity.

5Msample/s per measurement data processing produces a huge amount of data over time, especially if you are using all four channels and want to run the setup for several days. Depending on the measurement period, this could cause problems due to the user’s hard drive limitations. To counter this, we offer different decimation steps for the displayed data. This also helps filter out noise.

The autoranging feature ensures the lowest absolute error for a measurement that requires high dynamic range (e.g. wake-up process of an NB-IoT module). Every shunt has four different scales. Each scale is ideal for measurements within a certain range. Autoranging automatically switches scales based on the measurement.

Our new event chart offers the unique capability of being able to correlate different IP and signaling events. Users are able to see which event (e.g. sending an SMS, attach to network, etc.) has what impact on increasing or decreasing the power consumption.

The R&S®RT-ZVC04A multi-channel power probe offers four different channels, which allows users to measure four different measurement points on one DUT. Users can observe how different sections of the DUT impact power consumption.
