Test data/Error inject
Each of the four transmission tests allow for errors
to be injected while the tests run.
To set up Error Inject, from the home screen select
SETUP>TESTS>ERROR and the ‘Setup:Inject’
screen is shown on the display (Fig 28). From the
three dropdown lists set:
Error type
:
FCS (Frame Check Sequence) helps determine the
way the network responds to errors – expect
frames with FCS errors to be discarded.
Pattern is a bit error. Frames that contain these
errors should return. A reason to inject pattern
errors is to confirm that the tester is counting bit
errors correctly – e.g. if two errors are injected, two
should be recorded.
Oversize or Undersize will inject frames of a size
that is one byte greater than the maximum or, one
byte
less
than
the
minimum
set
in
SETUP>NET>RJ45.
Errors
: Single or Ratio.
Select ‘Single’ and while a test runs, each time you
press INJECT (F3) (Fig 29) one error is injected.
Select ‘Ratio ’and while a test runs, when INJECT
(F3) is pressed errors are injected until you press
F3 again to stop them (Fig 30).
Ratio: Can be set from 1 in 10 to 1 in 10
13
(steps
in powers of 10). Sets the limit for ratio of errors to
be injected – e.g. if set to 1 in 10, then one error is
injected for every 9 good frames or bits.
