Model 2651A High Power System SourceMeter Instrument Specifications


SPECIFICATION CONDITIONS

This document contains specifications and supplemental information for the Model 2651A High Power System SourceMeter instrument. Specifications are the standards against which the 2651A is tested. Upon leaving the factory, the 2651A meets these specifications. Supplemental and typical values are nonwarranted, apply at 23 °C, and are provided solely as useful information.

Accuracy specifications are applicable for both normal and high-capacitance modes.

Source and measurement accuracies are specified at the 2651A terminals under these conditions:

  1. 18 °C to 23 °C, < 70="" percent="" relative="">
  2. After two-hour warm-up
  3. Speed normal (1 NPLC)
  4. A/D autozero enabled
  5. Remote sense operation or properly zeroed local operation
  6. Calibration period: One year

1 Full power source operation regardless of load to 30 °C ambient. Above 30 °C or power sink operation, refer to “Operating boundaries” in the Model 2651A Reference Manual for additional power derating information.
2 Quadrants 2 and 4 in the power envelope are trimmed at 36 V and 4.5 A.
3 Add 50 µV to source accuracy specifications per volt of HI lead drop.
4 For temperatures 0 °C to 18 °C and 28 °C to 50 °C, accuracy is degraded by ± (0.15 × accuracy specification)/°C. High-capacitance mode accuracy is applicable at 23 °C ± 5 °C only.
5 Derate accuracy specification for NPLC setting < 1="" by="" increasing="" error="" term.="" add="" appropriate="" typical="" percent="" of="" range="" term="" for="" resistive="" loads="" using="" the="" table="">
accuracy Specifications 6 18-bit ADC. Average of 1000 samples taken at 100 µs intervals.
7 At temperatures 0 °C to 18 °C and 28 °C to 50 °C; 100 nA to 10 µA accuracy is degraded by ± (0.35 × accuracy specification)/°C. 100 µA to 50 A accuracy is degraded by ± (0.15 × accuracy specification)/°C. High-capacitance mode accuracy is applicable at 23 °C ± 5 °C only
8 8 50 A range accessible only in pulse mode.
9 50 A range accuracy measurements are taken at 0.008 NPLC.
10 Average of 100 samples taken at 1 µs intervals.
11 Times measured from the start of pulse to the start off-time; see figure below.
time graph 12 Thermally limited in sink mode (quadrants 2 and 4) and ambient temperatures above 30 °C. See power equations in the Model 2651A Reference Manual for more information.
13 Times measured from the start of pulse to the start off-time; see figure below.
time graph 14 With measure and compliance set to the maximum current for the specified voltage range.
15 Add 50 µV to source accuracy specifications per volt of HI lead drop.
16 For sink mode operation (quadrants II and IV), add 0.6 percent of limit range to the corresponding voltage source accuracy specifications. For 100 mV range add an additional 60 mV of uncertainty. Specifications apply with sink mode enabled.
17 For sink mode operation (quadrants II and IV), add 0.6 percent of limit range to the corresponding current limit accuracy specifications. Specifications apply with sink mode enabled.
18 Includes measurement of SENSE HI to HI and SENSE LO to LO contact resistances.
19 High-capacitance mode specifications are for DC measurements only and use locked ranges. Autorange is disabled.
20 100 nA range is not available in high-capacitance mode.
21 Add an additional 2 nA to the source current accuracy and measure current accuracy offset for the 1 µA range.
22 With measure and compliance set to the maximum current for the specified voltage range.
23 Tests performed with a 2651A on channel A using the following equipment: Computer hardware (Intel® Pentium® 4 2.4 GHz, 2 GB RAM, National Instruments PCI-GPIB); driver (NI-488.2 Version 2.2 PCI-GPIB); software (Microsoft® Windows® XP, Microsoft® Visual Studio® 2010, NI-VISA version 4.1).
24 Exclude current measurement ranges less than 1 mA.
25 smua.measure.adc must be enabled and the smua.measure.count set to the burst length.
26 Fixed source range with no polarity change.
