3.2 Input and output connections
3-6
WF1945B
Sync signal output (SYNC OUT)
50
Ω
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 signal ground (floating from chassis)
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.
・
Waveform and sync signal output relationship (Waveform phase definition)
(1) Continuous oscillation mode (NORMAL)
①
Sinewave
