N7906A power assistant software
The APS N7906A power assistant
software is a free application
that works with the APS power
supplies. The power assistant
software provides three main
capabilities for working with the
APS power supplies:
•ControlanAPSpowersupply
using the Power assistant soft-
ware’s intuitive graphical user
interface
•Retrieveandviewdatafrom
the optional APS power supply
black box recorder
(see Figure 9)
•Performtriggerroutingand
configure logical trigger
expressions (see Figure 10)
The power assistant software is
available for download at:
www.agilent.com/find/powerassistant.
For more information on the
APS power assistant software,
refer to the APS user manual at:
www.agilent.com/find/APS-doc.
Single Output: 1 & 2 KW GPIB, LAN (LXI Core), USB

Notes:
1
Resistance programming accuracy varies with output current. For example, for an N7970A unit at 0.1 Ω with
a 50 A transient, accuracy is: (0.1 Ω*0.06%) + (1.6 mΩ*A/50 A) = 92 µΩ.
