Bypass Mode
Bypass mode also provides excellent passband accuracy and provides minimal signal attenuation up to
very high frequencies for those applications that need to measure signals of frequency exceeding 20 kHz.
For reference, the typical roll-off characteristic of Bypass mode is the following:
