SPECIFICATION CONDITIONS
This document contains specifications and supplemental information for the Model 2606B System
SourceMeter
®
instrument. Specifications are the standards against which the 2606B instruments are
tested. Upon leaving the factory, the 2606B instruments meet these specifications. Supplemental and
typical values are nonwarranted, apply at 23 °C, and are provided solely as useful information.
Specifications are for individual modules.
Source and measurement accuracies are specified at the 2606B 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

The System SourceMeter
®
will allow quadrant II and quadrant IV operation, however, it is intended for low power or short transient behavior.
Operation in quadrant II and quadrant IV could result in an overtemperature error.
