±256 V input voltage
Input channels with the ability to measure waveforms up to 256 V are ideal for analyzing
high-voltage and transient signals as seen in automotive and aerospace defense
applications. Most oscilloscopes and PXI digitizers have a maximum input range less
than 40 Vpk. This also reduces the need to add expensive input signal attenuation and
signal conditioning circuitry, saving test development time and money.
2-channel isolated, with ADCs per channel
In addition, since the ±256 V input voltage range is combined with 16-bit analog-to-
digital converters (ADCs), the isolated front-end and low input offset allows voltages
from as low as 250 mV to as high as 256 V to be measured simultaneously.
The M9217A’s individually isolated 2-channel inputs have been designed for high
performance with an A/D converter per channel to ensure the signals you measure
are accurately digitized without distortion or additional noise. Channel input range is
configurable from ±250 mV up to ±256 V, with a floating voltage up to ±40 V to accom-
modate differential waveform acquisition.
20 MSa/s sampling rate at 16-Bit resolution
The M9217A’s ability to support up to 20 MSa/s sampling rate at 16-bit resolution
enables sampling of transient waveforms like injector waveforms (Figure 1).
