论坛谁对TR6143有研究的吗？电压不稳
RT。有一台6143，老版本全金封的，最近开机发现电压不稳，电压成方波样式的折线情况。搜了下eev及本论坛，基本没维修帖，特来询问是TR6143吧，这种机器没电路图的
先检查下供电部分，以及功率板电解这些是否正常
还有就是这种机器好像可以设置为断续方式输出，具体要看看说明书 jincai2004 发表于 2026-2-4 11:26

对的 金封版的老6143 搞死我了
没啥了，当年修一个这种机器，还好CPU板正常，供电部分和功率部分严重电腐蚀断线，电源部分也烧掉不少东西，前后花2个多月业余时间修复，现在还是正常的 我有一台6243，输出是由几种类型的，你这个是不是设置了编程呢个输出？
Source Modes
There are four source modes; DC, pulse, DC sweep, pulse sweep.
Then, the sweep modes are classified into three sweep types: linear
sweep, log sweep and random sweep (user programmable sweep).
The 6243/6244 is a DC voltage and current source/monitor
that offers wide ranging source and measurement as follows:
6243 Voltage: 0 to ±110V Current: 0 to ±2A
6244 Voltage: 0 to ±20V Current: 0 to ±10A
The 6243/6244 provides high accuracy with 4½-digit
source resolution and 5½-digit measurement resolution, a
variety of sweep functions, and a pulse measuring function
with a minimum pulse width of 1ms. Thus, it can be
used for a wide range of applications as a power source for
evaluation in research and development of semiconductors
and other electronic components or for characteristic test
systems in a production line.
The 6243/6244 can generates patterns necessary for device test
without exchanging data with an external controller, and read out
measurement results from the memory after the test. However, it
cannot generate pulses across polarities.
