Relafional Range@ Allowed AC Amplitude Voltage and DC Offset Volfage
Even valid combinations may cause errors in the process
of setting up those combinations. To avoid such errors,
reset the DC offset value to OV before changing the ampli-
tude, or change the setting specified in Figure 3-9 so that
the values are within the range of allowed settings.
Example:
Suppose that the existing amplitude is 1OOmV p-p/no
load and the DC offset is 500mV/no load. Assume that
you want to use an amplitude of 500mV p-p/no load
and a DC offset of 5V in combination. An error will oc-
cur if you set the DC offset to 5V before setting the am-
plitude. (The minimum AC amplitude when the total
voltage is over 1.5V/no load is 286mV p-p. The exist-
ing amplitude setting is below the minimum ampli-
tude value.) If you set the amplitude to 500mV p-p
first, and then set the DC offset to 5V, you can obtain
the desired amplitude and offset values without caus-
ing an error.
