• About measurement accuracy
• RF electromagnetic field and SMU measurement accuracy
Voltage and current measurement accuracy may be affected by RF
electromagnetic field of strength over 3 V/m at frequencies 80 MHz to
1 GHz and 1.4 GHz to 2.0 GHz, and 1 V/m at frequencies 2.0 GHz to 2.7
GHz. The extent of this effect depends upon how the instrument is
positioned and shielded.
• Induced RF field noise and SMU measurement accuracy
Voltage and current measurement accuracy can be affected by induced RF
field noise strengths greater than 3Vrms in the frequency range of 150 kHz
to 80 MHz. The extent of this effect depends upon how the instrument is
positioned and shielded.
