BIRST™ Flow Chart
Test Sequencer Front Panel for BIRST™. This allows any
combination of tests to be run in either single or multiple
sequences. All test data is displayed in the results window
and can be written to a data file.
It can be hard to confirm or identify faulty relays on complex
switching matrices. The user may be aware that the test
system is not behaving as expected but may be unsure if
it is a cabling fault, a software problem or a faulty matrix.
Discovering the source of the problem takes time and effort
users may not have when working to tight schedules.
To ensure low cost of ownership, Pickering Interfaces has now
incorporated a test tool, BIRST, into the BRIC.
BIRST
The BIRST is a sophisticated diagnostic tool, which allows a
complete relay self test of a BRIC module. The BIRST is an
easy to use, tool that is especially useful in remote production
sites where local technical support may be limited. It provides
the following features and capabilities:
• Complete BRIC, Matrix self-test capability
• High fault coverage, self-test tool
• Tests for all relay fault types (bad open or bad close)
• Identifies faults to individual component relay level
• Test sequencer allows detailed control of testing
• Test results shown on screen or sent to log file
• Runs single or repeat tests for maximum confidence Designed for Reliability and Serviceability
The BIRST provides a quick and cost effective way of
identifying the fault or simply providing reassurance that the
matrix is working correctly.
The design of Pickering Interfaces’ products ensures that relay
replacement is with a minimum of investment in tools. The use
of leaded relays in preference to surface mount ensures that
the replacement of one device will not stress others through
the use of re-flow techniques. Individual relay failures can be
corrected with little impact on the others in the matrix. This
maximizes the service life of the matrix even after a failure
has occurred and been repaired.
The repairer’s skills required are good understanding of
the extraction and replacement of leaded components.
Spare relays are included with many of Pickering’s lower
density matrix modules. Alternatively replacement parts are
readily available from Pickering Interfaces representatives.
The ability to replace failures locally ensures that system
downtime is minimized and transportation costs are avoided.

PXI 2 A BRIC MULTI-SLOT MATRIX MODULES (40-573)
pickering SECTION 1 - TECHNICAL SPECIFICATION
Relays have specific voltage and current ratings and can be damaged if these parameters are exceeded – this can happen
accidentally during test development and debug. Damaged relays can exhibit a variety of failures including:
• Permanent or intermittent open/short circuits
• Variable path resistance.
These are often very difficult to diagnose as they can erroneously connect signals together causing unpredictable UUT behaviour.
Historically, complex switching systems on platforms such as VXI and Pickering’s System 10/20 GPIB products have included
a degree of self test for the relays. But in PXI, the industry has not included self test on switching because of the compromises
introduced on density and cost when implementing previous self test architectures. As an alternative, some PXI switching
solutions include relay operation counters to attempt to predict when a relay will fail. Although it may be helpful to know how
intensively a relay might be being used it is not on its own a good indicator. The disadvantages are:
• Load conditions alone can impact the relay operating life by more than three orders of magnitude.
• Using the measure as a predictive maintenance tool (replacing relays when they have operated a number of times) can easily
degrade the reliability of a switching system because of the disturbance that relay replacement causes to adjacent devices
(not just relays), the risk of introducing a relay with “infant mortality” and even the potential for damaging the PCB when the
change is made, especially if the relays are surface mount devices.
Pickering has greatly improved the test methodology to the extent it is now possible to include full self test in PXI switch modules
with minimal impact on cost and switching density, welcome news for users who are used to having such features in their
solutions. BIRST will identify any relay failures in the switch module and is also capable of detecting relays with deteriorating
contacts which may indicate they are in the process of failing, as shown below.
To conduct a test the user simply disconnects the switching module from the UUT and test instrumentation and runs the supplied
application program. No supporting test equipment is needed; the test runs automatically and identifies any defective or suspect
relays within the module. If the switch module is connected directly to a Mass Interconnect receiver then BIRST may be executed
without removing these connections. The BIRST tool is not intended to entirely displace user-developed self test applications
that are built into some ATE systems. This system level test typically uses an external DMM and loop back mechanisms to check
for switching and cable harness faults. BIRST conducts its test when the UUT and instrumentation are disconnected from the
switching system, if BIRST finds no switching faults and a system level tool does find faults, the problem is with the cabling
system. The user does not have to design software to diagnose switching faults, considerably simplifying the design task for
system self test.
