Agilent Technologies 33120A User Manual

FSKey:SOURce {INTernal|EXTernal}
Select an internal or external
FSK source. The default is INT.
[ Stored in volatile memory ]
 When the internal source is selected, the rate at which the output
frequency “shifts” between the carrier frequency and hop frequency
is determined by the FSK rate specified (FSK:INT:RATE).
 When the external source is selected, the output frequency is
determined by the signal level on the rear-panel FSK terminal.
When a “low”
TTL level is present, the carrier frequency is output.
When a “high”
TTL level is present, the hop frequency is output.
 The maximum external FSK rate is 1 MHz.
 The Ext annunciator turns on when the function generator is waiting
for an external trigger signal.
FSKey:SOURce?
Query the internal
FSK source. Returns “INT” or “EXT”.
FSKey:STATe {OFF|ON}
Disable or enable
FSK modulation. To ensure proper operation, you
should enable
FSK after you have set up the other modulation parameters.
Only one modulation mode can be enabled at a time. When you enable
FSK, the previous modulation mode is turned off.
FSKey:STATe?
Query the state of the
FSK mode. Returns “0” (OFF) or “1” (ON).
