„
Sweep stop/restart input (SWEEP PAUSE IN)
Signal characteristics : Sweep stop = Low level
Sweep restart = High level
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 with about 10 k
Ω
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 V
→
+5 V = Sweep value is rising
+5 V
→
0 V = Sweep value is falling
Output voltage : 0 to +5 V (open)
Output impedance : About 1 k
Ω
Recommended load : 10 k
Ω
or more
Ground : Connected to chassis ground
Avoid shorting the output or applying an external signal. The unit can be damaged.
