[1] Analog capture for each channel is selectable from BNC or POD individually.
[2] Input bandwidth refers to the bandwidth of the analog input circuitry and the compensated A/D converter in all but the most sensitive input range.
[3] Timebase speeds faster than 50nS assume equivalent time sampling is used.
[4] User selectable analog input prescaler with x10 gain for use with low level signals or when input bandwidth limiting is required.
[5] Minimum measurable peak-to-peak sinusoidal waveform voltage when both resolution enhancement and input multiplier are enabled, when viewed as a waveform (Time) or viewed as a spectrum (Freq) and the minimum measurable average DC voltage (Mean).  
[6] In addition to the fast sample rates, a wide range of slow clock rates are supported. All clock rates support enhanced resolution capture.
[7] Specifies the maximum effective number of bits (ENOB) achieveable with resolution enhancement enabled.
[8] Includes UPP-02 Universal AC adaptor and US power cable as standard.
E&OE

Analog and logic probes are sold seperately.

不是完全开源的,这个示波器是98年circuit celllar 举办的一个什么比赛的冠军,是开放设计的。所有的硬件设计资料都开放, 但是核心的捕捉引擎(用PLD实现的)是不开放的。

虚拟的示波器和普通的示波器相比,有什么优缺点??
DS1002的虚拟示波器,4千块,块头比这个小一半。

虚拟示波器携带方便,不占地方,需求量少,相同指标下,价格贵不少,且需要与电脑配合使用,换一台电脑就要重新安装驱动和软件,软件分析能力相对强大,软件功能可扩展。
