Timing Chart
■
When the measurement mode is other than sample hold (trigger 2)
• When the measurement mode is set to normal, the measurement value of when the timing
input turns on is outputted.
• When the measurement mode is peak hold, bottom hold, peak-to-peak hold, average
hold or sample hold (trigger 1), the measurement value that is fixed by turning on the
timing input is outputted.
■
When the measurement hold is sample hold (trigger 2)
• After the timing input turns on, the measurement value fixed after the sampling period
+t ms is outputted.
The t-time is identified as follows.
Sampling rate 20 µs t=T2+4 ms
Other than 20 µs t=T2+3 ms
Refer to page 4-16 for T2 (input response time).
