• Data Module: Allows you to specify the data module to which the
M8061A module is connected.
• Demux Visa Resource: Allows you to provide the visa resource string
for N4877A. This is required to connect N4877A instrument with
M8020A.
In addition, this dialog displays the connection diagram and
connection instructions for each mode.
• Click Apply. Depending upon the configuration settings, the ports
which in which settings can be done do not ayou will see the
changes in the Module View. Some ports that are used by the data
module and M8061A modules will be disabled. For the block
diagram representation and interactively modify the settings of the
currently mode, switch to System View. For details, refer System
View with M8061A Integration on page 162.
M8062A Module
The M8062A (32Gb/s Front-end for J-BERT M8020A High-Performance
BERT) module has the following ports on its front panel:
On Pattern Generator Side
• Data In 1 and Data In 2 (Half Rate) - Single-ended, half-rate data
inputs from the M8041A module (3.5 mm, female).
• Data Out and /Data Out - Differential or single-ended, full-rate data
output to the device under test. Unused outputs must be terminated
into 50 . (2.4 mm, female).
• DMI In - Differential Mode Interference input. Applies a single-ended,
external interference source differentially to the data output (SMA,
female).
• CMI In - Common Mode Interference input. Applies a single-ended,
external interference source to both the normal and complement data
output signals (SMA, female).
• Clk Out - Half-rate Pattern Generator clock output. Carries the same
jitter as the full-rate data output.
• Clk In - Pattern Generator clock input (half-rate). Connect to clock
output of M8041A.
• Aux Clk In - Alternate Pattern Generator clock input (half-rate).
Typically unused.
• Electrical Idle In - This input is used to enable/disable the output
signal by an external control signal. If the input level is above the
threshold level the module enters electrical idle. Normal operation
resumes when the input level is below the threshold (SMA, female).
