High-density data acquisition
The U2781A chassis increases the
number of available channels when
any U2300 Series, U2500 Series, or
U2600 Series products are slotted into
the chassis. For example, when you
slot six U2331A Series products in the
chassis, it allows for an expansion of
up to 384 channels, providing a high-
density data acquisition solution.
Internal and external 10 MHz
reference clock
The U2781A is equipped with a
10 MHz reference clock. It is used
to synchronize the timebase of
the USB modular products slot
into the chassis for more precise
measurements.
Simultaneous Synchronization
Interface (SSI)
SSI provides synchronization
between the modular products in the
chassis by allowing the modules to
be configured as Master or Slave.
The Master module sends the SSI
signal to the Slave module via the
backplane trigger bus. Then, the
Slave module receives the signal
and begins synchronization with the
Master module. There are two SSI
configuration modes available —
single Master-multiple Slaves and
multiple Masters-multiple Slaves.
Please refer to the Agilent U2781A
USB Modular Product Chassis User’s
Guide for more information.
Triggering using Star trigger bus
The U2781A comes with a Star trigger bus, which offers precise synchronization
between USB modular products and the external trigger signal. The star trigger
bus provides dedicated trigger lines between the external trigger input and
slotted USB modules. You can also achieve precise triggering between each
USB modular product via the synchronized routing of the star trigger.
System option
The U2781A USB modular product chassis has a mountable rackmount kit,
which can be ordered separately (see “Optional Accessories” on page 8). This
allows for a better setup when the U2781A is integrated into a test system.
