Description
The softkey gives access to a menu of softkeys which enable the
following to be set:
• Termination voltage
• Output amplitude
• High output level
• Output ON/OFF switch
• Normal or inverted sense (pattern polarity)
• Clock to data output delay
• External data attenuation
• Data eye vertical cross-over
The attenuator setting allows the user to specify the level referenced to the far (non-pattern
generator) side of an external attenuator.
The data and data Amplitude and High-level may be controlled either together or
independently.
The softkeys are as follows:
This softkey selects the external termination submenu. Any
change of the selected termination causes the Amplitude to be
set to minimum. specifies an ac coupled
external termination, and disables the High-level control.
specifies a 0V dc coupled external
termination and specifies a −2V dc
coupled external termination. The range of High-level available
is affected by the 0V or −2V dc termination selected.
returns control to the main Data Output Menu without altering
any of the selections.
Enables the peak-to-peak amplitude of the data output to be
entered in units of volts or millivolts.
