WF1945B
Other:
• User units can be used for frequency, period, amplitude, DC offset, phase and duty.
• Even when user units are set, the actual output does not change.
• According to the coefficient and offset settings, setting resolution may be less precise when user units
are used.
• When using user units for the DC offset and phase in LOG selection, note the following.
If a negative value is set before the conversion to user units is made, an attempt is made to calculate
the logarithm of a negative value. Since the logarithm of a negative value cannot be a real number,
"OVER" is displayed.
Thereafter, user setup values can be arbitrarily changed. However, the DC offset and phase cannot
be converted to a negative value while user units are being used.
