Valid values are 8, 16, 32, 64, 128, 256, 512, 1024 and 2048. For Linux
operating systems only, you can select data size values from 2048, 4096,

Do one of the following to set the test frequency:
In the
Number of Tests
box, type or select the number of tests you
want to run. Testing stops when the passes complete. The valid range
is between 1 and 65535 for loopback tests and between 1 and 10,000
for read/write buffer tests.
Select the
Test Continuously
check box. You determine when testing
stops.

In the
On Error
box, click one of the following to determine how errors are
handled. This selection applies whether you entered the
Number of Tests
or selected
Test Continuously
.
Ignore on Error
—Ignores errors and continues the test sequence.
Stop on Error
—Stops the test sequence once an error is
encountered.
Loop on Error
—Uses the same data pattern and test until the failure
is cleared.
7.
In the
Test Increment
box, type or select the number of passes you want to
run before the test stops.
The valid range is between 1 and 10,000 and must be less than or equal to
the value in the
Number of Tests
box (see
). For example, if the
Number of Tests
box contains 100 and the
Test Increment
box contains
15, 100 tests are run in seven passes. The first six passes run 15 tests each;
the seventh pass runs 10 tests: (6
×
15) + 10 = 100.
