This document contains specifications and supplemental information for the Models 2634B, 2635B, and 2636B System SourceMeter™ instrument. Specifications are the standards against which the 2634B, 2635B, and 2636B are tested. Upon leaving the factory, the 2634B, 2635B, and 2636B meet these specifications. Supplemental and typical values are nonwarranted, apply at 23 °C, and are provided solely as useful information.
Source and measurement accuracies are specified at the 2634B, 2635B, and 2636B terminals under these conditions:
- 18 °C to 28 °C, < 70 percent relative humidity
- After a two-hour warm-up period
- Speed normal (1 NPLC)
- A/D autozero enabled
- Remote sense operation or properly zeroed local operation
- Calibration period: One year

TRIGGERING AND SYNCHRONIZATION CHARACTERISTICS
1 Full power source operation regardless of load or number of channels used to 30 °C ambient temperature. Above 30 °C or power sink operation, refer to “Operating Boundaries” in the Series 2600B System SourceMeter Reference Manual for additional power derating information.
2 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.
3 Add 50 µV to source accuracy specifications per volt of HI lead drop.
4 Derate accuracy specification for NPLC setting < 1 by increasing the error term. Add appropriate typical percent of reading term for resistive loads using the table below. 5 The 100pA range is not available with the Model 2634B.
6 10-NLPC, 11-Point Median Filter, < 200 V range, measurements made within 1 hour after zeroing. 23 ºC ± 1 ºC.
7 Under default specification conditions: ± (0.15% + 750 fA).
8 Under default specification conditions: ± (0.15% + 1 pA).
9 10 A range is accessible in pulse mode only. Accuracy specifications for 10 A range are typical.
10 Times measured from the start of pulse to the start off-time; see figure below
11 Thermally limited in sink mode (quadrants 2 and 4) and ambient temperatures above 30 °C. See power equations in the Series 2600B System SourceMeter Reference Manual for more information.
12 Voltage source operation with 1.5 A current limit.
13 With source settling set to SETTLE_SMOOTH_100NA
14 Add 50 µV to source accuracy specifications per volt of HI lead drop.
15 For sink operation (quadrants II and IV) without sink mode enabled, add 10% of compliance range and ±0.02% of limit settling to the corresponding voltage source accuracy specifications. For 200 mV range add an additional 120 mV of uncertainty. Specifications apply with sink mode enabled. 16 For sink operation (quadrants II and IV) without sink mode enabled, add 0.06% of limit range to the corresponding current limit accuracy specifications. Specifications apply with sink mode enabled.
17 Includes measurement of SENSE HI to HI and SENSE LO to LO contact resistances.
18 Contact check is not available with the Model 2634B.
19 Compliance equal to 100 mA. Delay factor set to 1
20 High-Capacitance Mode specifications are for dc measurements only.
21 100 nA range is not available in High-Capacitance Mode.
22 High-Capacitance Mode utilizes locked ranges. Auto range is disabled.
23 Part of KI Factory scripts. See the Series 2600B Reference Manual for details.
24 Tests performed with a Model 2636B 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, VISA™ version 4.1).
25 Exclude current measurement ranges less than 1 mA.
26 With default measurement delays and filters disabled.
