FSK Carrier Frequency
The maximum carrier frequency depends on the function selected as
shown below. The default is 1 kHz for all functions.
When the External source is selected, the output frequency is determined
by the signal level on the rear-panel Ext Trig connector. When a logic low
level is present, the carrier frequency is output. When a logic high level
is present, the hop frequency is output.
• Front-Panel Operation: To set the carrier frequency, press the Freq
softkey for the selected function. Then use the knob or numeric
keypad to enter the desired frequency.
• Remote Interface Operation:
[SOURce[1|2]:]FREQuency {<frequency>|MINimum|MAXimum}
You can also use the
APPLy
command to select the function, frequency
,
amplitude, and offset with a single command.
