Basic Pattern Test - Agilent Technologies E5900B User Manual

Basic Pattern test

The Basic Pattern test finds data bits in the specified memory range that are
stuck high or low. It also detects data lines that may be tied to power, ground,
or not connected at all.
How the Basic Pattern test works
This test writes the Pattern and the complement of the Pattern to the
Memory Range, and then compares the values in memory with what was
written. The complement of the Pattern and then the Pattern are then
written, read, and compared.
Example:
Entering the command
mtest bp -a4 -v1 -r2 20000000..2000000f=55555555
will produce the following memory writes and reads:
First
Write/Read
20000000 55555555
20000008 AAAAAAAA
If no errors were found, the following output would appear on your
screen:
M>mtest bp -a4 -v1 -r2 20000000..2000000f=55555555
Starting: Basic Pattern Test
Completed: Basic Pattern Test
Summary: 2 - PASSED
Instructions for using the Basic Pattern test
For help about performing a specific memory test using the Agilent 16700-
series logic analysis system, see page 95.
To use the Basic Pattern test from the command line interface, enter
mtest bp <parameters>. To see a list of the required parameters, enter
? mtest bp.
For general instructions on using the command line interface see page 88.
