FUNCtion:RAMP:SYMMetry {<percent>|MINimum|MAXimum}
FUNCtion:RAMP:SYMMetry? [MINimum|MAXimum]
Set the symmetry percentage for ramp waves. Symmetry represents the
amount of time per cycle that the ramp wave is rising (assuming that
the waveform polarity is not inverted). You can set the symmetry to any
value from 0% to 100%. The default is 100%. MIN = 0%. MAX = 100%.
The :SYMM? query returns the current symmetry setting in percent.
0% Symmetry
• For ramp waveforms, the APPLy command overrides the current
symmetry setting and automatically selects 100%.
• The symmetry setting is remembered when you change from ramp
wave to another function. When you return to the ramp wave
function, the previous symmetry is used.
• If you select a ramp waveform as the modulating waveform for AM or
FM, the symmetry setting does not apply.
OUTPut {OFF|ON}
OUTPut?
Disable or enable the front-panel Output connector. The default is "OFF".
When the output is enabled, the
generator's front panel. The OUTP? query returns "0" (OFF) or "1" (ON).
• The APPLy command overrides the current OUTP command setting
and automatically enables the Output connector ("ON").
• If an excessive external voltage is applied to the front-panel Output
connector, an error message will be displayed and the output will
be disabled. To re-enable the output, remove the overload from the
Output connector and send the OUTP ON command.
The OUTPut {OFF|ON} command changes the state of the output
connector by switching the output relay. However, this command does
not zero the voltage to be output before switching the relay. Thus, the
output signal may have "glitches" for about a millisecond until the signal
stabilizes. You can minimize these glitches by first setting the amplitude
