a. Assumes a 30 inch cable from the PNA 1.85 mm Test Port Out is used to provide the 10 MHz to 
67 GHz source signal. The standard configuration does not have a bias-tee in the 1.0 mm test head 
and uses this connection.
b. Assumes a 30 inch cable from the PNA Source Out bulkhead connector is used to provide the 10 
MHz to 67 GHz source signal. The Option 017 and 018 configurations includes a bias-tee in the 1.0 
mm test head and use this connection.
