1. Specifications are for one hour warm up, within one hour self-cal, slow AC filter.
2. For temperatures outside the range of 23 °C ± 5 °C, but within 0 °C to 50 °C, add 0.1 × accuracy specification per °C.
3. Repetitive reading at an aperture of 133 ms or higher.
4. If DCV source > 6 V, then add current * 4 ohms; if DCV source > 8 V, then add current * 30 ohms.

+3 to +15 V activates the trigger
Minimum trigger pulse width
Aperture + 50 µs
Trigger input impedance
3 kΩ
Edge
Selectable positive or negative edge
PXI bus trigger inputs
Trigger input voltage level range (via PXI backplane)
CMOS level (see PXI standard)
Minimum trigger pulse width
Aperture + 50 µs
Edge
Selectable positive or negative edge
Trigger features
Trigger sources Immediate, PXI trigger, external DIN connector, analog
threshold trigger source

1. 15,000 readings/second represent a typical maximum with a measurement aperture of 2.5 µs. Results will vary, depending
on what PC hardware, PXI hardware, and driver are used.
