You can select rising or falling for the valid edge of a trigger.
See "Enabling Trigger Input for during Measurement and Setting the Valid Edge of Trigger Input" (p. 136)
Signal function details
Input
TRIG
• When the trigger setting is the external trigger , measurement is performed
once with the falling (ON) or rising (OFF) edge of the TRIG signal. The edge direction
can be set in the setting screen. (Initial value: Rising (ON))
See: "Enabling Trigger Input for during Measurement and Setting the Valid Edge of Trig-
ger Input" (p. 136)
When the trigger source is set to the internal trigger , trigger measurement is not
performed.
• You can set whether to enable or disable TRIG signal input during measurement (during
output of the EOM signal (HI)).
See: "Enabling Trigger Input for during Measurement and Setting the Valid Edge of Trig-
ger Input" (p. 136)
LD0 to LD6 Selects the number of the panel to load.
If a trigger signal is input in external trigger mode, the selected panel is loaded and used for
measurement.
LD0, LD1 hen performing measurement in TRANSFORMER mode, select LD0 and input
the trigger signal. When performing measurement, select LD1
and input the trig-
ger signal.
LD-VALID Inputs a negative logic signal from an external device so that the selected panel number is
recognized as valid.
After TRIG
input, maintain a Low level until INDEX is outputted.
