The maximum input voltage of each logic analyzer probe is 40 volts
peak.
Pod Thresholds
Logic analyzer pods have two preset thresholds and a user-definable
pod threshold. The two preset thresholds are ECL (-1.3 V) and TTL
(+1.5 V). The user-definable threshold can be set anywhere between -
6.0 volts and +6.0 volts in 0.05 volt increments.
All pod thresholds are set independently.
