TSW200E1
2E17-1, 2E18-1, 2E20-1 O153, 2E20-1 O151, QRSS, 2E21-1, 2E22-1, 2E23-1, 2E25-1,
2E28-1, 2E29-1, 2E31-1, 2E32-1, or all Marks, all Spaces, alternating
Mark(M)/Space(S), Double Alt (‘1100’), 3 in 24, 1 in 16, 1 in 8, 1 in 4, D4 LA, D4 LD.
Other than these standards, there is the AUTO option. If the test is started with this
option, the TSW200E1 tries to synchronize automatically to the pseudo-aleatory patterns
that it gets. When the TSW200E1 gets the correct pattern, it starts to transmit this
pattern. There is a limitation concerning the detection of QRSS and 2E20-1 O151
patterns. Since they are very similar, the TSW200E1 units can synchronize in one of
then and begins to count eventual bit errors, it means that the correct pattern is the other
one. It is possible to opt for the USER and IDLE patterns. The USER pattern is any
chosen test sequence with up to 16 bits. Editing the USER pattern is done in the same
way as for the BERT/BLERT mode. For the IDLE pattern, the Test Set analyses the
frame structure only, and not the data. This option can be changed with the ← or →
keys.
•
Polarity : Selects signal polarity between NORMAL, where the selected pattern
sequence bits are normally transmitted or INVERTED, where the bits are inverted. To
change polarity, use the ← or → keys. This parameter allows the user to select
separately the polarity of the transmit and receive signals as normal (NORM) or inverted
(INV).
•
Idle Code : Selects the Idle Code to be transmitted in the non-selected channels. To edit,
press DATA. The ← or → keys move the cursor to the bit that will be changed. To
toggle the bit, use the alphanumeric keys. To exit the editing mode, press <F4>
(ENTER) to update the edited value or <F1> (EXIT) to cancel editing mode.
•
NFAS/NMFAS : The DEFAULT option keeps all bits at 1. The USER option allows the
programming of the NFAS/NMFAS word (Sa). To toggle between these two options use
the ← or → keys . Press DATA to edit. The bits of the NFAS/NMFAS word are then
displayed. They can be individually modified. The ← or → keys move the cursor to the
bit that must be changed. To alter the bit, use the alphanumeric keys. To exit the editing
mode, press <F4> (ENTER) to update the edited value or <F1> (EXIT), which cancels
editing mode.
•
ABCD Bits : The DEFAULT option keeps all the ABCD bits set to 1000. The USER
option allows programming of the 30 timeslot 16 ABCD words. This option is valid for
the PCM30 and PCM30C frames only. To toggle between these two options use the ←
or → keys. Press DATA to edit. Two channels per line and the corresponding ABCD
word are displayed. Inside the editing screen, press <F2> (EDIT) to edit the bits. The ←
or → keys move the cursor to the bit to be changed. Press ↑ or ↓ to change the frame to
be edited. Press <F4> (ENTER) to update the edited value or <F1> (EXIT) to cancel
editing mode.
