4.2.9 External Control Signals
These signals are I/O signals for synchronizing multiple units, scanner or DMM control, interlock and
other external controls.
The following table shows the signal names, levels and functions.
Table 4-8 External Control Signal Functions
Signal
Input/
Output
Level Impedance Function
TRIGGER IN Input TTL negative
pulse
(2 μs or more)
Approx. 10 kΩ • Start/step up in the sweep source mode or
memory recall mode
• Stops continuous operation.
SYNC OUT
*1 *3
Output TTL negative
pulse
(Approx. 10
ms)
Approx. 100 Ω
open drain
(Pulled up to +5 V
by 4.7 kΩ)
• Step up signal in the memory recall mode
or in the sweep source mode.
• Step up signal for the continuous function
in the DC source mode.
READY OUT
*1 *4
Output TTL negative
pulse
(Approx. 10
ms)
Approx. 100 Ω
open drain
(Pulled up to +5 V
by 4.7 kΩ)
• Outputs a pulse 10 ms or 50 ms after
changing the setting value.
STANDBY IN
*2
Input TTL negative
level
Approx. 10 kΩ • Sets Standby when the signal level
changes from LO to HI.
OPERATE
STANDBY IN
*2
Input TTL negative
level
Approx. 10 kΩ • Sets Standby when the signal level
changes from LO to HI.
• Sets Operate when the signal level
changes from HI to LO.
INTERLOCK
*2
Input TTL negative
level
Approx. 10 kΩ • Sets Standby when the signal level
changes from LO to HI.
• When the signal is "HI" or Open, Operate
cannot be turned ON.
OPERATE OUT
*2
Output TTL negative
level
Approx. 100 Ω
open drain
(Pulled up to +5 V
by 10 kΩ)
• Outputs LO in Operate status.
• Outputs HI in Standby or Suspend status.
OPERATE
SUSPEND IN
*2
Input TTL negative
level
Approx. 10 kΩ • Sets Standby when the signal level
changes from LO to HI.
• Sets Operate when the signal level
changes from HI to LO.
*1, *2: The same terminal is used by switching respectively.
*3: The SYNC OUT signal is not output for functions other than the continuous function in the DC source mode.
*4: When the step time is less than 0.1 sec, the output timing becomes 10 ms.
