Intelligent Signal Analyzer Module
The 8 channel Intelligent Signal Analyzer Module ISAM from CGS is a multifunctional module with 3 functions:

• PWM analyzer (decoder) with max. 8 channels
• Incremental decoder with max. 12 channels
• Edge counter with max. 8 channels

The 12 channel incremental decoder uses for decoding a state machine integrated in an FPGA to provide reliable values without counting errors. Such miscounting can occur during conventional decoding using I/O modules and software, e.g. by micro-vibrations (multiple directional change before the end of the signal sequence) caused by servomotors.

• Two channels each can be configured with a different function
• All channels work with a frequency of 100 MHz
• Possibility to connect up to 4 incremental decoders (inputs A, B and Z)
• X1, X2 or X4 decoding
• Digetal filter (glitch filter) for PWM
• 8 channels with programmable input threshold

The ISAM replaces the IDM.
