Real time clock
The Agilent N6705 DC power analyzer
has a built-in battery backed real
time clock. This allows for proper
time-stamping of logged data. It is also
used to tag files with correct creation
dates.
Front panel USB
The Agilent N6705 DC power analyzer
provides a convenient front panel USB
port designed exclusively for data
storage devices, such as USB memory
devices or USB hard drives. On devices
connected to this USB port, you can
save test setups, test results, and
screen images. It is also an easy way
to move test setup files between two
N6705 DC power analyzers or test
results between the DC power ana-
lyzer and a PC. You can also log data
directly to the USB device plugged into
the front panel. This extends the total
storage capability of the N6705.
Internal memory
The Agilent N6705 DC power analyzer
has 4 gigabytes of non-volatile storage.
This storage is shared between the
four DC outputs. It can be used for
saving test setups, test results, and
screen images. External USB storage
is supported for increased storage
capacity to log data longer.
Emergency stop
Should a hazardous situation occur
during testing, you can press the
large red emergency stop button on
the front panel of the Agilent N6705.
Pressing this easy-to-find button
immediately removes power from
the DC outputs. However, any data
collection (such as a scope trace or
data log) that is running at the time
will continue to run. By doing so, the

data you were collecting is saved and
you will get a record of what was
happening at the time of the event that
caused you to press the emergency
stop button. The measurements could
aid in failure analysis, repair, or debug-
ging of the DUT.
DUT protection features
Each Agilent N6705 DC power module
is protected against over-voltage,
over-current, and over-temperature.
A fault condition in one module can
be detected within 10 microseconds
by other modules so that they can be
quickly shut down to avoid hazardous
conditions on your DUT.
Output disconnect and polarity
reversal relays
Modules in the Agilent N6705 can
be individually ordered with optional
Output Disconnect Relays (option
761) or Output Disconnect/Polarity
Reversal Relays (option 760). See
table on page 20 for option 760 and
761 availability. All relays are built
into the module, so no additional
wiring is needed to incorporate the
relay function.
Although the plus and minus rail of
the output power mesh are physi-
cally disconnected from the output
terminals with options 760 and 761,
a small AC network is still connected
across the plus and minus output ter-
minals. This AC network is required
for EMI compliance.
With option 761, Output Disconnect
Relays, an emergency condition or
turning the DC output off causes
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, mechanical
relays switch the leads on both the
plus and the minus side of the power
supply, including the sense leads,
resulting in a voltage polarity reversal
at the DUT. In addition to polarity
reversal, option 760 provides the
same output disconnect function as
option 761.
Note: Output current is limited on
some modules when option 760
Output Disconnect/Polarity Reversal
Relays is installed. See the “Available
options” tables on page 20 for more
information about maximum current
limitations with option 760.
