Model N6705 User's Guide
SHOCK HAZARD Floating voltages must not exceed 240 VDC. No output
terminal may be more than 240 VDC from chassis ground.
Only connect outputs that have identical voltage and current ratings in series.
Agilent Models N678xA SMU and N6783A–x cannot be connected in series.
To prevent reverse currents from damaging the DC Power Analyzer when the
load is connected, always turn series-connected outputs on and off together.
Do not leave one output on while the other is off.
You can only use the series-connected outputs in "standard" power supply
mode. You cannot generate arbitrary waveforms, make scope measurements or
use data logging on outputs that are connected in series.
Connecting outputs in series provides a greater voltage capability
than can be obtained from a single output. Because the current is the
same through each element in a series circuit, outputs connected in
series must have equivalent current ratings.
The following figures show how to connect two outputs in series to a
single load. If voltage drop in the load leads is a concern, connect the
sense leads of output 1 and output 2 for remote sensing as shown in
the figure on the right. Connecting the +S terminal of output 2 to the
-S terminal of output 1 and connecting a jumper between +S and + on
output 2 compensates for the IR drop in the load lead from output 2
to output 1.
