1. Requires 86100 software revision 4.1 or above.
2. Filtering provided for Option 010 bands 2.4 to 4.0 GHz and 9.0 to 12.6 GHz, for Option 020 9.0 to 12.6 GHz and 18 to 25.0 GHz, for Option 40 9.0 to 12.6 GHz, 18.0 to
25.0 GHz, and 39.0 to 48.0 GHz. Within the filtered bands, a synchronous clock signal should be provided (clock, sinusoid, BERT trigger, etc.). Outside these bands,
filtering is required to minimize harmonics and sub harmonics and provide a sinusoid to the 86107 input.
3. For the 86107A with Option 020, the Agilent 11742A (DC Block) is recommended if the DC offset magnitude is greater than 200 mV.
The 86108A can be triggered through clock recovery of the observed signal, through an external reference clock into the precision
timebase section, or with the precision timebase operating on the clock signal recovered from the observed signal. The following speci-
fications indicate the 86100 system timebase specifications achieved when using the 86108A plug-in module. (The 86100 mainframe and
the 86108A module can also be triggered with a signal into the mainframe. In this configuration, the basic mainframe specifications are
achieved.)
