Data and Data (inverted) Outputs
Data and Data (inverted) Outputs
The following pattern generator data output features are accessed using the
key and its menu of softkeys.
Features
• Polarity - normal or inverted data.
• Data high level adjust.
• Data amplitude adjust.
• External termination voltage 0/−2V or ac coupled.
• External attenuator set 0 to 40 dB for 0V termination.
• Delay v clock adjust.
• Output ON/OFF selection.
• Vertical data-eye cross-over adjust.
• Independent control of high level, amplitude and ON/OFF for DATA and DATA.
Data output features not controlled by data output softkeys
• Output gating - controlled by AUXILIARY INPUT port (see Auxiliary Input descrip-
tion on page 4-10).
• Error add - (see Error Add paragraph on page 4-8).
