Load considerations for voltage source
The boundaries within which the 2606B operates depend on the load of the device-under-test (DUT)
that is connected to the output. The following topics show operation examples for resistive loads that
are 2
kΩ and 800 Ω, respectively. For these examples, the 2606B is programmed to source 10 V and
limit current (10 mA). In addition, the 2606B is programmed to limit power (60 mW) for the
Voltage source operation in power
(on page 4-6) example.
Normal voltage source operation
In the following figure, the 2606B is sourcing 10 V to the 2
kΩ load and subsequently measures 5 mA.
The instrument is also programmed to limit power (60 mW). As shown, the load line for 2
kΩ
intersects the 10 V voltage source line at 5 mA. The current compliance limit and the power
compliance limit are not reached (the instrument is not limited through its compliance settings).
