Chapter 3
• For arbitrary waveforms, the maximum amplitude will be limited if the data
points do not span the full range of the output
DAC (Digital- to-Analog
Converter). For example, the built-in “
SINC” waveform does not use the full
range of values between ±1 and therefore its maximum amplitude is 6.084 Vpp
(into 50 ohms).
• For arbitrary waveforms an inherent offset may be present (if the average of
the waveform is not equal to zero). The function generator calculates the
average of the data points and compares the average to zero volts. If the
average is not within two
DAC (Digital-to-Analog Converter) counts of zero
volts, an inherent offset is present.
FUNCtion:SHAPe?
[SOURce:]FUNCtion:SHAPe? queries the output function. Returns “SIN”, “SQU”,
“
TRI”, “RAMP”, “NOIS”, “DC”, or “USER”.
PULSe:DCYCle
[SOURce:]PULSe:DCYCle <percent>|MIN|MAX sets the duty cycle in percent for
square waves only. Duty cycle represents the amount of time per cycle that the
square wave is high. The default is 50%. [ Stored in volatile memory ]
Parameters
Comments • Duty cycle: 20% to 80%, in 1% increments (frequency ≤5 MHz).
40% to 60%, in 1% increments (frequency > 5 MHz).
The default is 50%.
• The duty cycle setting is remembered when you change from square wave to
another function. When you return to the square wave function, the previous
duty cycle is used. The APPLy command automatically sets the duty cycle to
