- Input specification
- 6-ch
- impedance 50-ohm single-ended
- Cross Talk 100dB@10MHz, 80dB@30MHz
- S/N 82dB or over
- LPF 400KHz-30MHz@-3dB
- AC coupling 1.0Vpp
- External clock: impedance 50-ohm, max 2.5Vpp
- Output specification
- 2-ch
- impedance 50-ohm differential
- DC coupling
- output level 1Vpp (0V to 1V)
