Frequency Characteristics; Variations In Range Of Use - Chauvin Arnoux MiniFLEX MA200 Notice De Fonctionnement

3.3. FREQUENCY CHARACTERISTICS

Range (Arms)
Pass band to ± 3 dB (Hz)
Tr and Tf from 10 to 90% (µs)
Td to 10% (µs)
Insertion impedance at 10kHz
(mW)
Tr: Rise Time
Tf: Fall Time
Td: Delay Time
(3): This is the equivalent pass band calculated by the formula:
BP = 0.35/Tt
with Tt = transition time (Tr or Tf)
