Models 2601B, 2602B and 2604B System SourceMeter Instrument Specifications
Specifications are subject to change without notice
SPEC-2602B Rev. B / February 2014 5 of 13
Voltage output headroom 40 V range
Maximum output voltage = 42 V – (total voltage drop across source leads).
Maximum 1 Ω source lead.
6 V range
Maximum output voltage = 8 V – (total voltage drop across source leads).
Maximum 1 Ω source lead.
Over-temperature protection
Internally sensed temperature overload puts the instrument in standby mode
Limit/compliance
Bipolar limit (compliance) set with a single value
Voltage:
10
Minimum value is 10 mV; accuracy is the same as voltage source
Current:
11
Minimum value is 10 nA; accuracy is the same as current source

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 100 mV range add an additional 60 mV of uncertainty. Specifications apply with
sink mode enabled.
11
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.
12
Add 150 µs when measuring on the 1 A range.
