Measure up to eight power rails at the same time
with highest accuracy
One R&S®RTE, R&S®RTO or R&S®RTP oscilloscope sup-
ports up to two R&S®RT-ZVC current probes so that it is
possible to observe eight power domains in parallel with
a DC accuracy of 0.1 % for voltage measurements and
0.2 % for current measurements. Ramp-up processes and
power rail tolerances can easily be tested with this probe.
The oscilloscope's SCPI remote control enables automatic
testing.
The R&S®RT-ZVC probe provides an extraordinarily high dynamic range for measuring both active state currents and sleep currents, in this example
12mA and 30µA. Automated measurements make it possible to calculate the total energy consumption.
Digital acquisition system
The R&S®RT-ZVC probe's digital acquisition system provides 18-bit resolution, a
5Msample/s sampling rate and 1MHz bandwidth. Each voltage and current input pair
forms a high dynamic range power measurement system.
High bandwidth with flexible filtering for noise
reduction
A bandwidth of 1 MHz and a sampling rate of
5Msample/s allows you to capture fast current pulses. To
analyze the overall power consumption of battery powered
devices, the very low sleep mode currents have to be cap-
tured at the same time. For very high dynamic range mea-
surements, the integrated lowpass filter reduces the band-
width down to 5 kHz and minimizes overall system noise.
