[:SOURce<n>]:FREQuency[:FIXed]
Syntax
[:SOURce<n>]:FREQuency[:FIXed] {<frequency>|MINimum|MAXimum}
[:SOURce<n>]:FREQuency[:FIXed]? [MINimum|MAXimum]
Description
Set or query the output frequency of the specified signal source channel when the modulation of the
specified signal source is not enabled; set or query the carrier frequency of the specified signal source
channel when the modulation of the specified signal source is enabled. The default unit is Hz.
Parameter
Name Type Range Default
<frequency> Real
Sine: 100mHz to 25MHz
Square: 100mHz to 15MHz
