1% to 99% (frequency < 100KHz)
20% to 80% (100KHz < frequency < 5 MHz)
40% to 60% (5 MHz < frequency < 10 MHz)
50% (frequency > 10 MHz
If the frequency is changed and the set duty cycle
cannot support the new frequency, the highest
duty cycle available at that frequency will be used.
A ―-221‖ error will be generated from the remote
terminal.
For square waveforms, the Apply command and
AM/FM modulation modes ignore the duty cycle
settings.
Syntax SOURce[1]:SQUare:DCYCle {< percent>
|MINimum|MAXimum}
Example SOUR1:SQU:DCYC MAX
Sets the duty cycle to the highest possible for the
current frequency.
Query Syntax SOURce[1]:SQUare:DCYCle? {MINimum|MAXimum}
Return Parameter <NR3> Returns the duty cycle as a percentage.
Query Example SOUR1:SQU:DCYC?
>+5.00E+01
The duty cycle is set 50%.
SOURce[1]:RAMP:SYMMetry
Set
Query
Description Sets or queries the symmetry for ramp waves only.
The setting is remembered if the function mode is
changed. The default symmetry is 100%.
0% symmetry is a ramp waveform with a negative
going transition. 100% symmetry is a ramp
waveform with a positive going transition.
