determined by the output units selected. This may occur when the units are
Vrms or dBm due to the differences in crest factor for the various output
functions. For example, if you output a 5 Vrms square wave (into 50 ohms) and
then change to the sine wave function, the function generator will
automatically adjust the output amplitude to 3.536 Vrms (the upper limit for
sine waves in Vrms). From the remote interface, a "Settings conflict" error will
be generated and the amplitude will be adjusted as described.
amplitude will be limited if the waveform 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 limited to 6.087 Vpp (into 50 ohms).
output waveform at certain voltages due to switching of the output
attenuators. The amplitude is controlled, however, so the output voltage will
never exceed the current setting while switching ranges. To prevent this
disruption in the output, you can disable the voltage autoranging feature using
the VOLT:RANG:AUTO command (see page 196 for more information).
by specifying a high level and low level. For example, if you set the high level to
+2 volts and the low level to -3 volts, the resulting amplitude is 5 Vpp (with an
associated offset voltage of -500 mV). See the VOLT:HIGH and VOLT:LOW
commands on page 195 for more information.
command and then set the offset voltage level using the VOLT:OFFS command.
You can set the dc level to any value between ±5 Vdc into 50 ohms or ±10 Vdc
