a. The CGL depth of 1024 entries in conjunction with a multiscan count of 256 provides an effective CGL depth
of up to 256K entries.

b. The maximum retrigger frequency depends on the board type. For DT301 and DT302 boards, the maximum
retrigger frequency is 155 kHz. For DT303 and DT304 boards, the maximum retrigger frequency is 219 kHz.
For DT321 and DT322 boards, the maximum retrigger frequency is 165 kHz. The maximum retrigger
frequency is based on the number of samples per trigger, as follows:
Min. Retrigger = # of CGL entries x # of CGLs per t 2
