Subrate Outputs
Permits errors to be added at a fixed rate. The fixed rate can be
varied in powers of ten between the limits of 1E−3 and 1E−9.

Description
The softkey gives access to a menu of softkeys which permit the
level and termination of the subrate data and clock to be setup.
Subrate Data Softkeys
Sets the subrate data output termination to ac.
Sets the subrate data output termination to 0V.
Sets the subrate data output termination to −2V.
Enables the peak-to-peak amplitude of the subrate data output to
be entered in units of volts or millivolts.
Enables the entry of the value for the subrate data high output
level in units of volts or millivolts.
Sets the subrate data outputs to use emitter coupled logic levels.
It also resets the Data Amplitude and Data Hi-Level to default
values.(Data Amplitude +500 mV; Data Hi-Level 0V)
Subrate Clock Softkeys
Sets the subrate clock output termination to ac.
Sets the subrate clock output termination to 0V.
Sets the subrate clock output termination to −2V.
Enables the peak-to-peak amplitude of the subrate clock output
to be entered in units of volts or millivolts.
