Category pulse component handler
When using this type of handler, the SourceMeter pulses one of the four handler lines
when a pass or fail condition occurs. The handler then places the DUT in the bin assigned
to that pulsed line. When interfacing to this type of handler, a maximum of four compo-
nent handler bins are supported.
If the handler requires low-going pulses, then the four digital output lines of the Source-
Meter must be initially set to high. This initial HI, HI, HI, HI clear pattern on the output
lines represents a no action condition for the handler since it is waiting for one of the lines
to go low. A line goes low when the defined fail or pass pattern sets it low. For example, if
you want a particular test failure to pulse line #4 of the handler, the defined fail pattern has
to be HI, HI, HI, LO. When the failure occurs, line #4 will be pulled low, and the DUT will
be placed in the bin assigned to that pulsed line.
If the handler requires a high-going pulse, the four digital output lines of the SourceMeter
must initially be set low. The LO, LO, LO, LO clear pattern represents the no action condi-
tion for the handler. When one of those lines are pulled high by a defined pass or fail bit
pattern (i.e., LO, LO, LO, HI), the DUT will be placed in the bit assigned to that pulsed
line.
Category register component handler
When using this type of handler, the SourceMeter sends a bit pattern to three handler lines
when a pass or fail condition occurs. This bit pattern determines the bin assignment for the
DUT. With the pass/fail pattern on the output, line #4 is then pulsed. This end-of-test
(EOT) pulse latches the bit pattern into the register of the handler, which places the DUT
in the assigned bin. When interfacing to this type of handler, a maximum of eight compo-
nent handler bins are supported.
If the handler requires a a high-going or low-going EOT pulse, program SourceMeter for
3-bit operation and appropriate EOT mode.
NOTE The EOT and 3-bit modes are configured from the CONFIG LIMITS MENU. See
“Configuring limit tests,” page 12-19.
