Quick-Check Procedure
1. Connect Port 1 and Port 2 of the network analyzer to switch’s Port 1 and
Port 2 respectively.
2. Refering to
Table 2
(standard drive) or
Table 3
(TTL drive), apply
appropriate drive voltage to ensure switch is in position A (path 1
connected to path 2, path 3 connected to path 4). Measure S
11
, S
21
and
S
22
and verify against specifications in
Table 6
.
3. Now, still in position A, disconnect switch’s Port 1 and Port 2 from
network analyzer. Then, connect network analyzer’s Port 1 and Port 2 to
Port 3 and Port 4 of the switch. Measure S
11
, S
21
and S
22
and verify
against specifications in
Table 6
.
4. Disconnect Port 3 and Port 4 from network analyzer. Connect Port 1 and
Port 2 of the network analyzer to switch’s Port 1 and Port 4 respectively.
5. Refering to
Table 2
(standard drive) or
Table 3
(TTL drive), apply
appropriate drive voltage to ensure switch is in position B (path 1
connected to path 4, path 2 connected to path 3). Measure S
11
, S
21
and
S
22
and verify against specifications in
Table 6.
6. Now, still in position B, disconnect switch’s Port 1 and Port 2 from
network analyzer. Then, connect network analyzer’s Port 1 and Port 2 to
Port 2 and Port 3 of the switch. Measure S
11
, S
21
and S
22
and verify
against specifications in
Table 6
