• Noise characteristics (filter ON)
Voltage source: 0.01 % of V range (rms.)
Current source: 0.1 % of I range (rms.)
• Overshoot (filter ON), typical
Voltage source: 0.03 % of V range
Current source: 1 % of I range
• Range switching transient noise (filter ON)
Voltage ranging: 250 mV
Current ranging: 70 mV
• Slew rate: 0.2 V/s (maximum)
• Voltage range, resolution, and accuracy (high speed ADC)
See Table 4-9.
• Current range, resolution, and accuracy (high speed ADC)
See Table 4-10.
Specified measurement resolution is limited by fundamental noise limits.
Minimum displayed resolution is 1 aA at 1 pA range by 6 digits.
Measurements made in the lower ranges can be greatly impacted by vibrations
and shocks. These specifications assume an environment free of these factors.
