Sampling at 100 kHz is possible for 1-channel measurement only.
Operating Switches START/STOP, ZERO, READ
Method of Setting Measuring Conditions From PC or CF card in which measuring conditions are written beforehand
Start/Stop of Recording From PC, panel switch or ext. contact points
Balance Adjustment From PC, panel switch or ext. contact points
LED Lamps POWER : Lights up when the EDS is turned on.
SYNC : Lights up to indicate synchronization condition.
MEAS : Lights up to indicate measurement in progress.
1, 2, 3, 4 : Lights up to indicate channel status.
READ : Lights up to indicate condition setting in progress.
Operation Modes Trigger : START signal from PC or a press of the front panel
START/STOP button starts recording. It stops recording upon recording to a preset number of measured values or when receiving STOP signal from PC or when the START/STOP button is pressed once again.
Operation Modes
Manual START signal from PC or a press of the front panel START/STOP button lets it wait for trigger signal, and starts recording when the trigger condition is satisfied. It stops recording upon recording to a preset number of measured values. Pretrigger data may be included in the number of measured values by setting.
Trigger Functions
Trigger Source External trigger signal, analog input
Trigger Level Set for analog trigger mode only,
in the full scale range in plus and minus directions.
Trigger Slope Up, down or both
Pretrigger Data Points to be Recorded : Set in a range of 0 to 2000.
Backup Functions Setting conditions, balance adjustment data (Saved in the nonvolatile memory)
LAN Port 10BASE-T/100BASE-TX
Connector : RJ-45 modular jack
Monitor Display Waveform, bar graph and numeric data is monitored on the PC via a LAN port.
Data Storage CF card (128 MB to 2 GB, writing speed 45x)
