Input B High Frequency Sensitivity Test Configuration; Input B Sensitivity High Frequency Performance Limits - Racal Instruments 2251A Operator's Manual

If Option 11 is installed connect the 2251A internal reference output to the external
signal source 10 MHz Input. Configure the external signal source to accept the
10MHz reference from the 2251A.
4.1.7.4 Connect the Signal Generator to the 2251A as shown in Figure 4-4.
