1. SPECIFICATION CONDITIONS
This document contains specifications and supplemental information for the Keithley Instruments Models 2601 and
2602 System SourceMeters
Upon leaving the factory, the Models 2601 and 2602 meet these specifications. Supplemental and typical values
are nonwarranted, apply at 23°C, and are provided solely as useful information.
The source and measurement accuracies are specified at the SourceMeter CHANNEL A (2601 and 2602) or
SourceMeter CHANNEL B (2602) terminals under the following conditions:
1. 23°C ± 5°C, <70% relative humidity.
2. After two-hour warm-up.
3. Speed normal (1 NPLC).
4. A/D auto-zero enabled.
5. Remote sense operation or properly zeroed local operation.
6. Calibration period: one year.

Temperature coefficient (0°C–18°C and 28°C–50°C): ±(0.15 × accuracy specification)/°C.
Maximum output power and source/sink limits:
±3.0A, four-quadrant source or sink operation.
Voltage regulation: Line: 0.01% of range. Load: ±(0.01% of range + 100 V).
Noise 10Hz–20MHz (peak-peak): 25mV typical into a resistive load.
Current limit/compliance:
Accuracy same as current source.
Overshoot: <±(0.1% + 10mV) typical (step size = 10% to 90% of range, resistive load, maximum current
limit/compliance).
Guard offset voltage: <10mV typical (Iout
1 Add 50 V to source accuracy specifications per volt of HI lead drop.
2 Full power source operation regardless of load to 30°C ambient. Above 30°C and/or power sink operation, refer to
Section 8, "Operating boundaries" in the Series 2600 Reference Manual for additional power derating information.
3 For sink mode operation (quadrants II and IV), add 12% of limit range and ±0.02% of limit setting to corresponding
current limit accuracy specifications. For 1A range, add an additional 40mA of uncertainty.
Specifications are subject to change without notice.
