- 03:53, 14 October 2024 Peter talk contribs created page Signature analysis (Created page with "'''Signature Analysis''' is a method to simplify (field) troubleshooting of complex digital systems, developed at Hewlett-Packard in the early 1970s. The idea is to describe "known good" states of signals in the system – typically when in some diagnostic / troubleshooting mode – as a CRC of that signal, when referenced to a known clock and defined start/stop conditions. The concept was introduced in [https://doc.xdevs.com/doc/HP_Agilent_Keysight/journals/1977-0...")

It is directly connected to the output of QA703 (an LM201 op-amp). Since the analog output connector is a open two-prong type it is very susceptible to accidental shorting. After replacing the op-amp, my instrument came back to life. I added a 1 kΩ resistor in series with the external output connector, to prevent acc...")
