1
Output current is derated 1% per °C above 40°C.
2
Applies when measuring 4096 data points (SENSe:SWEep:POINts = 4096).
3
Applies when measuring currents that remain within the low range. Due to thermal settling, when transitioning
from measuring full-rated output current (the worst case), to measuring the current within the low range, the
low range accuracy specification is typically met within 5 seconds after the current has transitioned into the
low range. Accuracies within this 5 second settling period are typically 2X the specified accuracy or better.

Series and parallel operation
To increase the available power,
identical models can be operated
in series for g reater output voltage
or in parallel for greater output
current.
To simplify parallel operation, the
N6700 offers virtual channels, a
firmware based feature that allows
the N6700 system to treat up to
4 channels as a single, synchronized
channel. Once confi gured, all func-
tions (sourcing, measurem ents,
triggering, protection, and status
monitoring) behave as if there is
1 channel of up to 4 times t he
capacity of a single channel, with-
out writing a single line of code
to manage the interaction and
synchron ization of the paralleled
power supplies.
Triggering
The N6700 MPS mainframe has
hardware trigger in/trigger out sig-
nals which permit the N6700 to be
synchron ized with external events.
Output disconnect relays
Modules in the N6700 can be
individually ordered with optional
Output Disconnect Relays (optio n
761) or Output Disconnect/Polarity
Reversal Relays (option 760). With
option 761, Output Disconnect Relays,
mechanical relays disconnec t both
the plus and minus side of the
power sup ply, including the sense
leads . With o ption 760, Output
Disconnect/Polarity Reversal Relays
switch the leads on both the plus
and minus side of the power
supply, including the sense leads,
resulting in a voltage polarity
reversal at the DUT.
