Softkey Menu Descriptions
Data Output Menu
Enables the entry of the value for the data high output level in
units of volts or millivolts.
Enables the entry of the value for the data high output level in
units of volts or millivolts.
Sets the data and data outputs to use Emitter Coupled Logic ECL
levels. It also resets the Data Amplitude and Data High-level to
default values. (Data Amplitude +850 mV; Data High-level
-900 mV)
Enables the data and data outputs to operate together (track) or
independently.
Enables the user to enter the value of an external data attenuator
in decibels and read from the display the data amplitude value at
the far end of the attenuator. Changing the value also resets the
Data Amplitude and Data High-level to default values
(+500 mV and −0V respectively).
Permits the data output signal to be switched off. When off the
data output is set to 0V.
Permits the data output signal to be switched off. When off the
data output is set to 0V.
Toggle the data outputs to be either normal or inverted in sense.
Enables the entry of a time delay by which the data output
should lag the clock output. The delay is entered in picoseconds
and may be negative (in which case the data leads the clock).
The entry is rounded to the nearest picosecond.
Enables the entry of a value which vertically adjusts the voltage
at which the 1 to 0 transitions and the 0 to 1 transitions cross.
The data output cross-over adjustment is independent for the
data and data outputs and is unaffected by the
selection. The user value entered specifies a
signed deviation of the cross-over from the calibrated 50%
setting which is normally used. The range of this control will
vary between instruments and may differ between the data and
data outputs. While offering repeatability on any given output,
the value is uncalibrated and the user entered value should not be
read as corresponding with either volts or percentage. This
function is provided to allow optimization of the cross-over in
critical applications or compensation of non-linearities in the
external equipment.
