NF WF1943B - Sync Signal Output (SYNC OUT)

3.2 Input and output connections
WF1943B
3-6
 Sync signal output (SYNC OUT)
50Ω
SYNC OUT
Output waveform :
Output voltage : 0 V/+5 V (open)
Output impedance: 50
Ω , unbalanced
Load impedance: More than 45
Ω
Status at output off : High impedance
Ground : Connected to chassis ground
Avoid shorting the output or applying an external signal. The unit can be damaged.
・
Output connection note
The SYNC OUT impedance is 50
Ω . By using coaxial cable with 50 Ω characteristic impedance for
connection to other equipment, waveform disturbance can be reduced. Although 50
Ω termination is
possible, the high level voltage is reduced by about half.
