Analog capture for each channel is selectable from BNC or POD individually.
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.
Timebase speeds faster than 50nS assume equivalent time sampling is used.
User selectable analog input prescaler with x10 gain for use with low level signals or when input bandwidth limiting is required.
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).
In addition to the fast sample rates, a wide range of slow clock rates are supported. All clock rates support enhanced resolution capture.
Specifies the maximum effective number of bits (ENOB) achieveable with resolution enhancement enabled.
Includes UPP-02 Universal AC adaptor and US power cable as standard.
E&OE
Analog and logic probes are sold seperately. mark 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。 MARK 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。 关注mark。 mark下~ 想做一款虚拟示波器，标记 mark~~~~~~~ 关注一下。 mark~~~~~~ 不错，我也想看看。 不错，先mark下。 虚拟示波器好用不？
