DVM, the environmental chamber, and the pressure con-
troller through other vendors.
The 14XXDASBOARD, in conjunction with the
14XXMUXBOARD modules, allows the user to compen-
sate up to 112 units. IEEE-488 commands select the
active DUT and communicate with the MAX14XX appli-
cation circuits. All system voltage measurements are
multiplexed for use with a single external DVM. Each
DUT interfaces to the 14XXMUXBOARD through a general-
purpose transition board, which provides digital inter-
face signals and low-noise analog inputs. The
14XXDASBOARD is required to operate the
14XXMUXBOARD. All driver software is incorporated
into the 14XXDASBOARD firmware. Sensor compensa-
tion procedure is implemented using National
Instruments’ LabView program. Customers may have to
adapt portions of the compensation procedure if they
are using a pressure controller, oven, or DVM that is
different from the type for which the system was
designed.
The system will be available free to all customers who
order MAX14XX. Minimum order quantities apply.
