5.2 Units

Other:
• User units can be used for frequency, period, amplitude, DC offset, phase and duty. Also, CH1 and
CH2 can be set independently.
However, at the channel mode difference (DIFF) setting, all CH1 user unit settings (formula, name,
coefficient and offset) are copied to CH2.
“3.3 Basic operation (■Channel modes and settings)”, cf.
• 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 output to
FUNCTION OUT cannot be converted to a negative value while user units are being used.
