Kenwood CS-1575D Service Manual

CS-1575D9ADJUSTMENTTo obtain the best performance, periodically calibrate theunit. Sometimes, only one mode need be calibrated, whileat other times, all modes should be calibrated. When onemode is calibrated, it must be noted that the other modesmay be affected. When calibrating all modes, perform thecalibration in the specified sequence.The following calibration requierd an accurate measuringinstrument and an insulated adjusting flat blade screwdriv-er. If they are not available, contact your dealer. For opti-mum adjustment, turn the power on and warm up thescope sufficiently (more than 30 minutes) before starting.Before calibrating the scope, check the power supply volt-age.TEST EQUIPMENT REQUIERDThe following instrument or their equivalent should beused for making adjustment.PREPARATION FOR ADJUSTMENTControl SettingsThe control settings listed below must be used for eachadjustment procedure.Exceptions to these settings will be noted as they occur.After completing a adjustment, return the controls to thefollowing settings.Digital Multi-MeterDL-712(KENWOOD)Impedance : More than10MΩ, Measuring range :0.2V to 1000VSine-WaveGenerator651B(YHP)Frequency : 10Hz to10MHz, constant voltageover tuning rangeSine-WaveGeneratorSG-503(Tektronix)Frequency : 50kHz to100MHz, Output impedance: 50Ω, constant voltage overtuning rangeSquare-WaveGeneratorPG-506(Tektronix)Output signal : 1 kHz,Amplitude : 10mVp-p to10 Vp-p, Accuracy : within±1 %, Rise time : 35ns orless100 kHz, Rise time : 1 ns orlessColor PatternGeneratorCG-921(KENWOOD) –Oscilloscope CS-6040(KENWOOD)Sensitivity : more than 1 mVFrequency response : Morethan 150 MHzTime-MarkerGeneratorTG-501(Tektronix)Time mark : 0.5 s to 0.1 μsrepetive waveformHigh-VoltageProbe – Input Impedance : 1000MΩTermination – Impedance : 50ΩAccuracy : within 3 %Termination – 3 watts type impedance :50ΩCapacitancemeterTC-1100(KENWOOD) –DC standard R6142(Advantest) –NAME OF KNOBS POSITIONINTENFOCUSPOSITIONTRIGGER LEVELVARIABLE (GND)VARIABLE (ATT)SWEEP TIME / DIVSOURCEDISPLAY MODEAC-GND-DCPHASE DISPPOWERTable 212 O'clock12 O'clock12 O'clock12 O'clockFully clock wiseFully counter clock wiseFully counter clock wiseDUALDUAL HACOFFOFFTestEquipmentMinimumSpecificationModel
