  • When do side view problems occur?
    the system components are mismatched
    the dc voltage supply is too low
    a probe is mounted in an area with not enough side clearance

  • When do crosstalk problems occur?
    when two probes are mounted too close together
    when the system components are mismatched
    when a probe is mounted in an area with not enough side
    when the dc voltage supply is too low
