: ± (10 mV + 4% of predetermined value)
• Resolution: 5 mV
• Input signal condition: 1 kHz to 50 MHz (single auto trigger, repeat auto trigger)
• Setpoint time: 0.7 s (typical *1) (single auto trigger, repeat auto trigger)
Sampling • Sampling mode: Can be selected from time stamp mode and hardware histogram mode
• Maximum sampling rate:
Continuous 14 M samples/s (approx. 71-ns intervals)
7 M samples/s (approx. 142-ns intervals) in the case of duty ratio and phase difference measurements
• Maximum sample size (maximum number of data items)
• Time stamp mode: 32,000
(16,000 in the case of duty ratio and phase difference measurements)
• Hardware histogram mode: 99,999,999
(excluding duty ratio and phase difference measurements)
• Sampling interval
MIN, 1 µ s, 2 µ s, 4 µ s, 10 µ s, 20 µ s, 40 µ s, 100 µ s, 200 µ s, 400 µ s, 1 ms, 2 ms, 4 ms
MIN is equivalent to the interval for the maximum sampling rate.
Must be selected for time stamp mode only.
• Maximum sampling time: 320 s (after the arming)
*1: Typical values are described in terms of typical of average performance. However, they cannot be guaranteed.
*2: Measured under the reference operating conditions specified in 12.10 “General Specifications”, after elapse of warm-up time, with the
DC input coupling and 1M Ω input impedance.
