Hardkey and Softkey Reference
AM
Ext 1 AC-Coupled
This softkey lets you input an external, AC-coupled, amplitude modulation signal
to the EXT 1 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 1 input has multiple uses but can be used for only one modulation at
a time. If, for example, you were using the external 1 input in a frequency
modulation configuration for
FM Path 1, and then you configured AM Path 2 to
also use the external 1 input, the signal generator would turn off
FM Path 1 and
assign the external 1 input to your
AM Path 2 configuration. (For the purpose of
this discussion, the external 1 AC-coupled input is the same as the external 1
DC-coupled input.)
