3.2 Input and output connections
WF1945B
3-10
 Sweep stop/restart input (SWEEP PAUSE IN)
Signal characteristics : Low level ; sweep pause
High level ; sweep restart
Input voltage : High level≧+3.9 V
Low level≦+1.6 V
Input voltage range : −0.5 to +5.5 V
Input impedance : Pull up to +5 V at approx. 10 kΩ
Ground : Connected to chassis ground
Do not apply a signal exceeding the above input voltage range. The unit can be damaged.
 Sweep X-drive output (SWEEP X-DRIVE OUT)
Signal characteristics : 0 to +5 V ; sweep increase
+5 to 0 V ; sweep decrease
Output voltage : 0 to +5 V (open)
Output impedance : Approx. 1 kΩ
Recommended load : Above 10 kΩ
Ground : Connected to chassis ground
Avoid shorting the output or applying an external signal. The unit can be damaged.
