Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 3: Basic Operation
Using the analog outputs
Each analog output provides a -10 V to +10 V DC output analogous to the input current. The
analog output signal will nominally source a ±10 V proportional, but inverted, signal to the input
current on all measurement ranges. For example, with a +1 mA current on the 2 mA measurement
range, the analog output voltage would be -5 V. Table 3-8 list typical analog output voltages for
various ranges and input currents.

Range Input current Analog output
20 nA +10 nA -5 V
2 µA -2 µA +10 V
20 µA +7 µA -3.5 V
2 mA +0.5 mA -2.5 V
20 mA -15 mA +7.5 V
