Ext 2 AC-Coupled
This softkey lets you input an external, AC-coupled, amplitude modulation signal
to the EXT 2 INPUT connector. The modulation signal is tested for voltage and a
display annunciator will report a high or low condition if the voltage is >
±3% of
1Vpk.
The external 2 input has multiple uses but can be used for only one modulation at
a time. If, for example, you were using the external 2 input in a frequency
modulation configuration for
FM Path 1, and then you configured AM Path 2 to
also use the external 2 input, the signal generator would turn off
FM Path 1 and
assign the external 2 input to your
AM Path 2 configuration. (For the purpose of
this discussion, the external 2 AC-coupled input is the same as the external 2
DC-coupled input.)
