GP1F351T/GP1F351R
s Features
1. Electric and optical signal compatible design
( Three kinds of terminals are
integrated into a single unit).
2. Compact design with small jack
compatible mini-plug
( Less than 1/2 in volume of GP1F32T/R )
3. OPIC type
( Direct interface to microcomputer
of the I/O signals )
( High fidelity real sound reproduction)
4. High speed data transmission
Signal transmisson speed: MAX. 8Mbps
( NRZ signal )
s Applications
1. MD, DCC
2. Portable CD, DAT

Set the trigger on the rise of input signal
to measure the jitter of the rise of output
Set the trigger on the fall of input signal
to measure the jitter of the fall of output
Note) ( 1) The waveform write time shall be 4 seconds. But do not allow the waveform to be distorted by incresing
the brightness too much.
( 2) VCC = 5.0 ±0.05V ( State of operating)
( 3) The probe for the oscilloscope must be more than 1MΩ and less than 10pF.
