M8061A Window
The M8061A is a 2:1 multiplexer to characterize serial interfaces of up to 28.4 Gb/
s with optional de-emphasis to extend the rate of J-BERT N4903B pattern
generator. The M8061A window is shown in the following figure.
The M8061A window contains the following tabs:
1
DataOut Tab - provides parameters to set the amplifier, deemphasis and
interference. For more information, refer to the section “DataOut Tab” on page
56.
2
ClkGen Tab - provides parameters to select clock source. For more information,
refer to the section “ClkGen Tab” on page 58.
3
Electrical Idle In Tab - provides parameters to set electrical idle in. For more
information, refer to the section “Electrical Idle In” on page 58.
The range of the parameters provided by M8061A window are listed in “M8061A
Parameters and Range” on page 58.
The DataOut tab provides parameters to set the Amplifier, Deemphasis and
Interference.
You can set the amplifier using the following parameters:
• Auto Range: Used to enable/disable Auto Range. Enabling the Auto Range will
allow J-BERT N4903B software to switch to amplitude ranges automatically
without user intervention. Amplitude range can be between 50 mV -1.2 V.
• Amplitude Range: Used to select one of the 8 pre-defined amplitude ranges
manually. This parameter is disabled if the Auto Range option is enabled.
