2 Specification and supplemental characteristics Warranted specifications are denoted by **, and all others are supplemental characteristics. Specifications are valid after a 30-minute warm-up and 3 ± 5 ºC. All these characteristics are defined by the 4-bit acquisition resolution of the CX3300 mainframe unless otherwise stated. See Device Current Waveform Analyzer data sheet (publication number: EN) for the mainframe characteristics. Overview of measurement accuracy Measurement accuracy can be affected by RF electro-magnetic field having the strengths greater than 3 V/m in the frequency range of 80 MHz to GHz or V/m in the frequency range of GHz to.7 GHz. The extent of this effect depends upon how the instrument is positioned and shielded. CX0A Performance Characteristics Table.
