72
measurement ranges allows you to
accurately measure low-level (nA)
currents.
This quad–output source is easy
to integrate into a test system. The
hardware connections are intended
for quick configuration and the
software is built on the straight-
forward standard SCPI
command set.

Notes:
3
Time for output voltage to recover to within 40 mV of former value after a change from
0.25 A to 0.5 A or 0.5 A to 0.25 A
4
Time for output current to recover to within 1 mA of former value after a change from
-1 V to +1 V or +1 V to -1 V.
5
Time from start of bus communication to final byte returned on bus. Assumes the default
of 5 points 30.4 µs apart.
