: REPAIRS of HP 8594A SPECTRUM ANALYSER with FREQ UNCAL error message
I measured 10 pin connector on YTO (5086-7833) oscillator with digitalmultimeter after the analyser was switched -on.
pin nos. standardsignal obtained
Pin1 = minus 15v = minus 15.02v
pin2 = a gnd = -
pin3 = a gnd = -
pin4 = +5v = +5v
pin5 = maincoil+ = +14.81v
pin6 = maincoil- = +9.63v
pin7 = a gnd = -
pin8 = +15v = +14.83v
pin9 = FM-signal = 0.041v
pin10 = FM+signal = 0.041v
Are these obtained values at pin 5,6, 9, 10 right or wrong.
Please suggest , ur help appreciated
