Tektronix TDS7104示波器的翻新维修记录

一位爱好者在硅谷跳蚤市场以300美元购得一台Tektronix TDS7104示波器，该设备原价为700美元1。这台1 GHz带宽、最大采样率为10Gs/s（单通道）的设备重39磅，但购入后存在多个故障1。

该示波器的主要问题源于PC主板上的CMOS备用电池失效，导致设备启动故障1。爱好者更换了CR2032电池后，屏幕出现显示异常1。随后他尝试通过升级固态硬盘来改进性能，采购了64GB mSATA SSD和相应的mSATA到IDE 44针2.5英寸适配器，总投入50美元1。原硬件为IBM Travelstar 6GB IDE驱动器1。

经过重新安装Windows 2000 Pro系统并配置必要的驱动和固件后，设备恢复正常工作1。最终采用了32GB mSATA SSD的配置1。改造带来了显著的性能提升：系统启动时间从原来的2分50秒缩短至1分35秒1。同时，原设备的授权许可密钥得以成功恢复，高级抖动分析选项已被启用1。

An individual successfully restored a Tektronix TDS7104 oscilloscope after identifying and resolving multiple hardware and software issues. The 1 GHz bandwidth instrument with a maximum sampling rate of 10 Gs/s in single-channel mode was purchased for $300, negotiated down from an initial asking price of $700 1. The device, weighing 39 pounds, had failed to start due to a failed CMOS backup battery on the PC motherboard 1. After replacing the CR2032 battery, the owner encountered display anomalies and subsequently discovered a failing hard drive—an IBM Travelstar 6GB IDE drive 1.

Rather than restoring the original aging storage, the owner attempted to upgrade the system by installing a 64GB mSATA SSD with an mSATA-to-IDE 44-pin 2.5-inch adapter at a combined cost of $50 1. This upgrade proved unsuccessful, prompting a decision to reinstall Windows 2000 Pro and return to a smaller 32GB mSATA SSD configuration 1. After reinstalling the operating system and configuring necessary drivers and firmware, the oscilloscope returned to full functionality 1. The refurbishing effort yielded tangible improvements: boot time decreased from 2 minutes 50 seconds to 1 minute 35 seconds 1. Additionally, the owner successfully recovered the authorization license key and enabled the advanced jitter analysis option 1.
