A-4 Technical Data
Measurement Ranges and Tolerances
Essential Performance
The Merlin™ PSA provides diagnostic information related to the implanted lead and provides pacing
pulses at a rate and amplitude set by the operator.
The Merlin PSA operates in conjunction with the Merlin™ PCS Model 3650; therefore, the essential
performance defined for the Merlin PCS governs and limits the available performance that is exhibited
by the Merlin PSA EX3100.
