Re: Tektronix 2430A occasionally fails some tests

The scope was never touched internally (the nvram battery is still the original one and no recap was made). I guess I found a "solution" to the problem: if I let the scope warm up for like 10-15 minutes, I can do all the self cals and diagnostics I want and no error is thrown. This way, the scope works fine indefinitely. Is this possible in your experience?
