The typical value is a representative or standard value. It is not a warranted value.
CAUTION
Do not apply a voltage that exceeds the maximum input voltage to the input
connector. This may cause damage to the input section.
Note
When connecting the probe for the first time, perform phase correction of the probe according
to the description given in section 3.6. Failure to do so will cause unstable gain across
different frequencies, thereby preventing correct measurement. Phase correction of the
probe must be performed when the probe changes or the TA120E changes.
