Plug High Power Mainframes Into
Standard AC Sockets Without
Dedicated High Current AC
Circuits
When you first turn on the N6702C
1200 W MPS mainframe, the mainframe
automatically senses the power available
from the AC line. If the AC line voltage
is such that the resulting current would
exceed a standard AC outlet rating, the
mainframe automatically scales back
the available output power to prevent
overloading the AC line. The N6702C will
limit the output power to 600 W allowing
the high power mainframe to be plugged
into any standard outlet. This is very
convenient for initial bench checkout of
the MPS system. It is also very convenient
for
test development, which is typically done
on the bench when DUT is not yet driven
to full power. You can also control this
power reduction by manually allocating
less than the full available mainframe
power among the modules. As a result,
the N6702C will draw less power (and
less current) from the AC line.
Triggering
The N6700 Low-Profile MPS mainframe
has hardware trigger in/trigger out signals
which permit the N6700 to be synchronized
with external events. For example, a switch
closure in the fixture can trigger the N6700
to apply voltage to the DUT or take a
measurement.
Drivers
The N6700 comes with both VXIplug&play
drivers and IVI-COM drivers. LabView drivers
are also available at NI.COM.
Programming Language
The N6700 supports SCPI (Standard
Commands for Programmable Instruments).
Firmware Updates
The N6700 firmware is stored in FLASH
ROM and can be easily updated when new
features become available. Firmware can be
downloaded into the N6700 over GPIB,
LAN, or USB using the supplied firmware
update utility program. Keysight recommends
that you keep your N6700 system up to
date with the latest firmware available at
www.keysight.com/find/N6700firmware.
Output Disconnect And Polarity
Reversal Relays
Modules in the N6700 can be individually
ordered with optional Output Disconnect
Relays (option 761) or Output Disconnect/
Polarity Reversal Relays (option 760). See
the table on page 14 for option 760 and
761 availability. All relays are built into the
module, so no additional wiring or rack
space is needed to incorporate the relay
function.
Although the plus and minus rail of the
output power mesh are physically discon-
nected from the output terminals with
options 760 and 761, a small AC network
is still connected across the plus and minus
output terminals, This AC network is
required for EMI compliance.
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, 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”
table on page 14 for more information
about maximum current limitations with
option 760.
