3.3.2 Frequency Counter
This instrument can measure the duty ratio and frequency of TTL-compatible level signal, with
frequency range of 1OOmHz-100MHz.
When we use the frequency counter function, the TTL-compatible level signal inputs through an
external digital modulation or frequency counter interface (INPUT/CNT connector)

compatible level signal is inputted through external digital modulation/frequency counter
interface (INPUT/CNT connector), the frequency counter refreshes display.
