• Models with the letter “P”
— For law in pitch-and-catch mode:
Number of consecutive channels used in a configuration (for the pulsing and
receiving channels) ≤ Maximum active channels
Example with model FLT32128-P-O: pulsing channels P1 to P16, and
receiving channels P17 to P32
— These models have a lower output impedance, so it means a higher voltage in
the load compared to models “R”.
• Models with the letter “R”
— For law in pitch-and-catch mode:
Number of pulsing channels ≤ Maximum active channels
Number of receiving channels ≤ Maximum active channels
Example with model FLT32128-R-O: pulsing channels P1 to P32, and
receiving channels P33 to P64
— These models have a higher output impedance, so it means a lower voltage in
the load compared to models “P”.
• Hardware limitations
Hardware limitations occur when performing pitch-and-catch inspections (see
Figure 5-1 on page 44). Those limitations are described in Table 6 on page 44.
