CHAPTER 2: View Mode
DTR, DSR
The form of handshaking you want.
After you press STOP to stop the
BERT test, a report will display. It
will look something like the screen
sample shown above. Interpret the
results as follows:
Chars Sent
The total number of characters sent,
up to 999,999,999.
Chars recv
The total number of characters
received, up to 999,999,999.
Rec in sync
Total number of characters received
that are the same as those sent.
Elap second
Total elapsed time the test took to
complete (in seconds).
BERT
Percentage of bit errors to total bits
transmitted.
Average trip time per block
(ms)
An average of the amount of time in
milliseconds it took for one block to
make the loop (in milliseconds).
Block Errors
Number of blocks received that
contained at least one error.
Bit Errors
Total number of bits received in
error.
Blocksize
Each of the patterns available from
the previous screen (FOX, FOX2,
ASCII, etc.) is a different length.
Blocksize is the number of bytes in
the pattern that you chose (a pattern
is also known as a “block”).
Error Free Sec
Percentage of the total time (100%)
that the transmission had no errors.
BLERT
Chars sent 999 Block Errors 9
Chars recv 9 Bit Errors 9
Rec in sync 9 Blocksize
Elap second 7 Error Free Sec %

TEST COMPLETED
Press START/STOP to end test.
