Major diagnostics are incorporated
to
offer
substantial improvements to system reliability because the user is
alerted to channel malfunctions. This approach also reduces bus traffic because the Status registers do not require
constant polling. Power-On, Self-Test (POST) diagnostic can immediately initiate (D3) test. See
Programming
Instructions for further details.
Three different tests (one on-line and two off-line) can be selected:
The (D2) test
initiates automatic background bit testing. Each channel is checked every 5
°
to a test accuracy of
0.05
°
and each Signal and Reference is always monitored. Any failure triggers an Interrupt (if enabled) and the results
are available in status registers. The testing is totally transparent to the user, requires no external programming, has
no effect on the standard operation of this card and can be enabled or disabled via the bus.
The (D3) test
initiates a BIT test
that disconnects all input channels from the outside and connects them across an
internal stimulus that generates and tests 72 different angles to a test accuracy of 0.05
°
. External reference is not
required. This testing requires no external programming, and can be enabled or disabled via the bus.
The (D0) test
is used to check the card and the cPCI interface. All input channels are disconnected from the outside
world thus allowing user to write any number of angles to the card and then read the data from the cPCI interface.
External reference is not required for this test.
This board can operate over a "C" or "M" operating temperature range (See part number). The "C" version (0°C to
+70°C) uses standard high quality commercial semiconductors. The "M" version (-55°C to +85°C, used for severe
environmental condition, uses high quality extended temperature semiconductors. Conduction cooling, using a thermal
plane and wedge locks, can be specified by adding "W" to P/N. A stiffener improves vibration response. Both sides of
the board can be conformal coated (See P/N). All “M” boards are burned in for 24 hours and cycled from -55°C to
+85°C.

resolution is equivalent to 1,024 cycles (4,096 transitions) etc. Differential outputs. The
encoder resolution is fixed and does not change with speed. (Optional, see P/N).

Each channel can be set to a different angle differential. When that differential is
exceeded, an interrupt (if enabled) is triggered. Default: “Ch. disabled”. Msb=180
