MSOX2012A逻辑分析仪无法解码

嗨，我最近购买了MSOX2012A示波器。
我的主要用途是能够实时可视化并调试包含模数转换器（ADC，A2D ......）的系统。
我需要能够同时看到至少一个模拟信号和至少一个SPI总线。
令我惊讶的是，数字频道根本无法解码。
甚至不支持一种串行协议，这是非常奇怪的，因为任何低级廉价的基于微控制器的逻辑分析仪都可以轻松解码大多数常见的串行信号，如SPI，I2C和UART。
我试过你的“串行解码”插件对我来说没用，它只解码模拟通道，我只有两个模拟通道，我至少需要其中一个用于我的模拟信号。
我知道你的实时串行解码器是在ASIC中实现的，而我的模型只能在模拟通道上使用，但串行数字协议的解码非常简单，并且计算要求低。
大多数现代微控制器都实现了这一功能。
你能实现某种基于软件的，甚至是“离线”（不是在运行模式下）串行解码吗？
这将节省我切换到另一个范围的麻烦。
现代逻辑分析仪可以解码串行数据。
如果您的产品对大多数现代实施都没用，请不要声称您的产品有逻辑分析仪。
您甚至无法解码经典的8位总线，因为您需要至少两个数字通道用于时钟和启用/ CS信号。
我知道你的3000系列示波器可能会做我需要的但是它要贵得多。
更新：我检查了其他MSO制造商：Tektronix：MSO2012B + DPO2EMBD它（价格相同）Rigol：MSO4012它（价格相同）Hameg：HMO1022 + HO3508 + HOO10有它（价格差不多）Siglent MSO /
SDS2102 +功能基因。
+串行解码有它（有点便宜）Lecroy：MS-250 +串行解码选项有它（更贵但更好）所以，实际上只有安捷伦不会在他们的“MSO”上的数字串行通道上触发和解码编辑：David14 on Mar

  Hi,

I very recently purchased the MSOX2012A scope.
My main intended use is to be able to visualize in real time and debug systems that include analog to digital converter (ADC, A2D...) .

I need the ability to see at least one analog signal and at least one SPI bus simultaneously.
  
To my surprise the digital channels cannot be decoded at all. Not even one serial protocol is supported, this is very strange because any low level cheap micro-controller based logic analyzer can easily decode most common serial signals like SPI, I2C and UART. I tried your "Serial Decode" add-on it is useless to me, it only decodes analog channels and I only have two analog channels and I need at least one of them for my analog signal. I know that your real time serial decoder is implemented in the ASIC and on my model is only available on the analog channels, but the decoding of serial digital protocols is very simple and has low computational requirements. Most modern micro-controllers implement this feature.
Can you implement some sort of software-based, even "offline" (not in run mode) serial decoding? this will save me the trouble switching to another scope.
A modern Logic Analyzer can decode serial data. Please do not claim that your product has a logic analyzer if it is useless for most modern implementations. You cannot even decode a classic 8bit bus because you need at least two more digital channels for the clock and enable/CS signals.   
I know that your 3000 series scopes can probably do what I need but it is much more expensive.

Update:
I checked other MSO manufacturers:

Tektronix: MSO2012B + DPO2EMBD Has it (about the same price)  
Rigol: MSO4012 Has it (about the same price)
Hameg: HMO1022 + HO3508 + HOO10 Has it (about the same price)
Siglent MSO / SDS2102 + function gen. + serial decode Has it (somewhat cheaper)
Lecroy: MS-250 + serial decode option Has it (more expensive but better)  

So, actually only Agilent wont trigger and decode on digital serial channels on their "MSO"
