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 greater 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 configured, all func-
tions (sourcing, measurements,
triggering, protection, and status
monitoring) behave as if there is
1 channel of up to 4 times the
capacity of a single channel, with-
out writing a single line of code
to manage the interaction and
synchronization of the paralleled
power supplies.
Triggering
The N6700 MPS mainframe has
hardware trigger in/trigger out sig-
nals which permit the N6700 to be
synchronized with external events.
Output disconnect relays
Modules in the N6700 can be
individually ordered with optional
Output Disconnect Relays (option
761) or Output Disconnect/Polarity
Reversal Relays (option 760). With
option 761, Output Disconnect Relays,
mechanical relays disconnect both
the plus and minus side of the
power supply, including the sense
leads. With option 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.
