Purpose
This command selects one of the FM modes.
•
CONTinuous selects continuous modulation
•
TRIGered selects triggered modulation
•
GATEd selects gated modulation

Response and default
The 3155 returns POS, or NEG depending on its present setting. Default is POS.
FREQuency{<freq>|MINimum|MAXimum}
Purpose
This command modifies the frequency of the standard waveform in units of Hertz (Hz). It has no affect on ar-
bitrary waveforms.
•
<freq> sets the waveform frequency
•
<MINimum> sets the waveform frequency to its lowest value
•
<MAXimum> sets the waveform frequency to its highest value
Parameter type
Numeric
Parameter range
<freq>
100e-6 to 50e6
FREQuency?
Response and default
The 3155 returns the present frequency value. The returned value is in standard scientific format (for exam-
ple: 100mHz would be returned as 100E-3 – positive numbers are unsigned). Default value is 1e6.
