Diagram 11. Connections of the M8061A with J-BERT N4903B
The Data In 1, Data In 2 and Aux Clk In of M8061A have to be connected to Aux
Data Out, Data Out and Aux Clk Out ports of the J-BERT N4903B, respectively. The
connections should be made using the matched cable kit with the part number
M8061-61601. The Data Output and Data Output have to be connected to the device
under test.
N O T E
Any unused output of the Pattern Generator has to be terminated with 50 Ohm.
The M8061A provides a differential signal to the DUT. The M8061A can be used in
combination with J-BERT N4903B as shown below.
The M8061A is a 2-slot AXIe module that can be controlled via USB from J-BERT’s
user interface.
For using the CMI and DMI inputs of M8061A, you can connect any sinusoidal
source with a voltage swing of 0 to 400 mV single ended. You can, for instance,
use the sinusoidal sources of N4903B option J20. Use a single ended connection
from any of the P1 or P1 complement, P2 or P2 complement outputs and terminate
all unused outputs with 50 Ohm. Though, it is possible to connect the normal and
complement of P1 or P2 outputs with the DMI and CMI inputs of M8061A
simultaneously, however both will have the same modulation.
