Introduction
Specifications
• Maximum guard offset voltage
± 1 mV (HPSMU)
± 3 mV (MPSMU, HRSMU)
± 4.2 mV (HRSMU with ASU, Iout ≤ 100
μA)
• Noise char
acteristics (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/μs (ma
ximum
)
• Voltage range, resolution, and accuracy (high speed ADC)
See Table 2-23.
• Current range, resolution, and accuracy (high speed ADC)
See Table 2-24.
Specified measurement resolution is limited by fundamental noise limits.
Mi
nimum disp
layed resolution is 1 aA at 1 pA range by 6 digits.
Measurements made in the lower ranges can be greatly impacted by v
ibrations
and shocks. These specifications assume an environment free of these factors.
