External Sampling (EXT.SMPL)
15.2 External Sampling (EXT.SMPL)
Externally inputting the signal allows you to set the sampling rate at any value.
How to an input signal
1
Connect the external sampling terminal of the instrument and the sampling signal-outputting
device with the SMB cable.
See “2.4 External Sampling (EXT.SMPL)” in the Quick Start Manual.

3
Tap the [External sampling] button to set it to [On] .
4
Tap the box to the right of the [External sampling] box, and then from the list, choose which
direction to used for reception of the external sampling signal.
To accept a rising edge: [ ]
To accept a falling edge: [ ]
To accept both a rising edge and falling edge: [ & ]
5
Input pulse waves or square waves to the EXT.SMPL terminal. The waves have to be with a
high-level voltage of between 2.5 V and 10 V and a low-level voltage of between 0 V and 0.8 V.
Available voltage range High level: 2.5 V to 10 V; low level: 0 V to 0.8 V
Pulse width High and low level: 50 ns or more
Response frequency 10 MHz or less
Maximum input voltage 10 V DC
