SOURCE SPECIFICATIONS (continued)
NOTES
1. Add 50µV to source accuracy specifications per volt of HI lead drop.
2. High Capacitance Mode accuracy is applicable at 23°C ±5°C only.
3. Full power source operation regardless of load to 30°C ambient. Above 30°C and/or power sink operation, refer
to “Operating Boundaries” in the Series 2600B Reference Manual for additional power derating information.
4. For sink mode operation (quadrants II and IV), add 0.06% of limit range to the corresponding current limit
accuracy specifications. Specifications apply with sink mode operation enabled.
5. Full power source operation regardless of load to 30°C ambient. Above 30°C and/or power sink operation, refer
to “Operating Boundaries” in the Series 2600B Reference Manual for additional power derating information.
6. 10A range accessible only in pulse mode.
7. High Capacitance Mode accuracy is applicable at 23°C ±5°C only.
8. Full power source operation regardless of load to 30°C ambient. Above 30°C and/or power sink operation,
refer to “Operating Boundaries” in the Series 2600B Reference Manual for additional power
derating information.
9. For sink mode operation (quadrants II and IV), add 10% of compliance range and ±0.02% of limit setting to
corresponding voltage source specification. For 200mV range add an additional 120mV of uncertainty.
10. Add 50µV to source accuracy specifications per volt of HI lead drop.

12. Thermally limited in sink mode (quadrants II and IV) and ambient temperatures above 30°C. See power equa-
tions in the Reference Manual for more information.
13. Voltage source operation with 1.5 A current limit.
14. Typical performance for minimum settled pulse widths:

5 V 0.5 W 1% 300 µs
20 V 200 W 0.2% 200 µs
180 V 180 W 0.2% 5 ms
200 V (1.5 A Limit) 200 W 0.2% 1.5 ms

1 A 200 W 1% 500 µs
1 A 180 W 0.2% 5 ms

Typical tests were performed using remote operation, 4W sense, and best, fixed measurement range. For more
information on pulse scripts, see the Series 2600B Reference Manual.
