3.2.3 1ch TRx connection for bathtub jitter measurement
This section describes a connection example for performing bathtub jitter
measurement by using MP1862A, MP1861A, and MU181500B which is
installed to MP1800A.
When performing bathtub jitter measurement, connect the equipment as
shown in Figure 3.2.3-1 and according to the procedure below, because a
clean clock (clock without jitter modulation) needs to be input to
MP1862A.
[Equipment configuration]
MP1862A
MP1861A
MP1800A
MU183020A-x22/x23+x31
MU183040B
MU181500B
MU181000A
DUT (Device under test)
[Procedure]
1.
Connect the Clock Output connector of MU181000A and the Ext.
Clock Input connector of MU181500B by using the J1624A coaxial
cable that comes with MU181000A.
2.
Connect the Jittered Clock Output connector of MU181500B and the
Ext. Clock Input connector of MU183020A by using the J1624A
coaxial cable that comes with MU181500B.
3.
Connect the Data Input1/2 connectors on the rear panel of MP1861A
and the Data Output1/2 connectors of MU183020A respectively by
using coaxial cables. The coaxial cables must be one of the following:
• J1658A coaxial cables that come with MP1861A
• Coaxial cables that are of the same length
4.
Connect the Clock Output connector of MU183020A and the Ext.
Clock Input connector on the rear panel of MP1861A by using the
coaxial cable.
5.
Connect the Delayed Clock Output and MUX Clock Input connectors
on the rear panel of MP1861A by using the J1654A cable that comes
with MP1862A.
6.
Connect the Data Output and
Data
Output connectors on the front
panel of MP1861A to the DUT by using coaxial cables.
7.
Connect the DUT and the Data Input and
Data
Input connectors on
the front panel of MP1862A by using coaxial cables.
