Sziasztok! Találkozott már valaki ilyen problémával, a szkóp képcső képén kerek foltok vannak. Képcső foszfor kiégésre gondolok, de lehet hogy hibás az elképzelésem. Várom az javaslatokat, mi a hiba. Felélesztettem egy Tektronixot és ezt produkálta.
Hello.
This is my first post on the forum.
I have a defective meter Tektronix DC502 Frequency Option1. SM fits the DC501. The damage is that it always displays "1111111". Generator 5MHz is operational. 7490 dividers as well. Unless the system is damaged 74LS112 U165. On its output there does not appear, regardless of whether the generator is working or push reset. Can anyone confirm this?
Sorry for my English, I use google translate.
I have a problem with the Tektronix 7633rd Readout is not working. Displays only the spot, (no time base on the screen), from time to time, jump to the next position where it should be readout. After adjustment knob charcter scan, there's a readout, but the characters were, or blurred, or not drawn to the end - in pieces, imposed on themselves. The readout is off everything works.
For all kinds of advice I would be very grateful.
Sziasztok!
Van egy ilyen gépem és a következő hiba, hogy lassabb időnél szaggatot a jel.
Szerviz leírásom van hozzá. Tápot átnézte. Hol érdemes elkezdeni a hiba keresését?
