Carrier Waveform Shape
•
AM carrier shape: Sine , Square, Triangle, Ramp, or Arbitrary
waveform. The default is Sine.
•
You cannot use the noise function or dc volts as the carrier waveform.
•
Front-Panel Operation : Press any of the front-panel function keys
except
Noise
. For arbitrary waveforms, the
Arb
key selects the
waveform that is currently downloaded.
•
Remote Interface Operation :
FUNCtion:SHAPe {SINusoid|SQUare|TRIangle|RAMP|USER}
You can also use the
APPLy
command to select the function,
frequency, amplitude, and offset with a single command.
Carrier Frequency
•
Carrier frequency: 100
µ
Hz to 15 MHz (100 kHz for triangle and ramp).
The default is 1 kHz.
•
For arbitrary waveforms , the maximum carrier frequency depends on
the number of points specified in the waveform. The five built-in
arbitrary waveforms can be output at a maximum of 5 MHz.
•
Front-Panel Operation : Press the
Freq
key to select any valid
frequency for the selected function (the present amplitude and offset
voltage are used).
•
Remote Interface Operation :
FREQuency {< frequency >|MINimum|MAXimum}
