1. Before Using the Product
Resolution 10bits, maximum conversion speed is 10MSPS (100nsec), with simultaneous sampling of
2channels at a time
A 10bits high-speed A/D vonverter is used, the measurement at the highest conversion speed of
100MSPS(10nsec) is possible.
It is possible to sample 2 channels simultaneously.
Moreover, it is equipped with a mass on-board memory of 16M data that archieves continuous
sampling, regardless of the processing performance of the PC.
It is also equipped with bus master transfer function by which the sampling data is transferred to PC
memory with high speed.
A variety of settings for signal input such as impedance, range, filter and coupling can be performed.
Analog input channel's input impedance can be selected between 50Ω and 1MΩ.
The measurement using a general-purpose passive probe is also possible by 1MΩ.
According to the voltage level of signal source connected, a number of ranges can be swithed (When
1MΩ is set, there are 10 ranges between 40mVpk[±20mV] and 40Vpk[±20V]. When 50Ω is set, there
are 8 ranges between 40mVpk[±20mV] and 10Vpk[±5V]) , so that you can make good use of the 10bit
resolution.
By enabling the noise filter (low pass filter: 20MHZ ), it is possible to perform the measurement with
reducing the influence of mixed high frequency noise from signal source and ambient environment.
The input coupling can be selected from AC/DC/GND.
(AC is only available when 1MΩ is set.)
The synchronization between external instrument and the board is possible with the reference clock I/O.
The synchronization between other measuring instrument or another board with the same type becomes
easily for that the reference clock (10MHz) can be input/output.
It is possible to expand the number of channels by the synchronization between another board with the
same type, and measure the mixed signal by the synchronization between other measuring instrument.
Sampling can be controlled by software, conversion data comparison, external trigger, event controller
output, and similar start and stop conditions
Sampling can be setup to be started and stopped by software, conversion data comparison, external
trigger, or event controller output. Control of sampling start and stop is completely independent and a
separate setting is provided for each. It is also possible to specify that sampling stop after a specified
number of samples.
There are two kinds of comparison for conversion data. The one is implemented by comparing the
conversion data edge (rising edge, falling edge or both edges), the other one is implemented by window
trigger that is satisfied when conversion data go inside/outside a certain boundary.
BNC connector used for analog input, trigger and reference clock
The BNC connector used for the connector has a characteristic impedance of 50Ω and is of a type
commonly used for high speed analog signal.
