F E A T U R E S* Vertical axis provides high sensitivity and wideband width, 2 mV/div, 15 MHz ( - 3 dB).* Operates on A C , internal DC and external DC,each being selected automatically without usingpower selector switch.* The adoption of IC's throughout circuitry assureshigh performance and improved reliability.* The high voitage power for C R T as well as thepower for other circuits is fully stabilized, thusthe sensitivity and luminance are compretelyfree from effects of voltage variations,* X - Y operation is possible with CH2 amplifierused as X axis.The horizontal axis sensitivity is as high as 10mV/div, permitting accurate calibrations.* Sum and difference between 2 channels can bemeasured by the use of mode selector switchand CH2 selector switch.C O N T E N T SPageFeatures ^2SpecificationsControls on Panels *Operation ^Preliminary Operation ^Operating Procedures ^Power Supply ®Battery Charging 8Mounting of Hood ®Applications ^Dual-trace Applications ^Single-channel Applications 1^FM Receiver Adjustments 2 1X - Y Operations Applications 2 1Amplifier Square W a v e Test 2 3P R E C A U T I O N S 2 8M A I N T E N A N C E AND A D J U S T M E N TMaintenance 2 8Adjustment 2 9S C H E M A T I C D I A G R A M 3 1* Time base switch allows changeover betweenC H O P and A L T and between V (vertical) and H(horizontal) of T V s y n c separator circuit,automatically and electronically.* At AUTO position of T R I G L E V E L , it is possible tocheck the luminance at no-sighal time and to ad-just triggering level of input waveforms.* The employment of digital switch circuit andmechanical parts cleverly mounted on circuitboards assure improved reliability.* T h e o v e r - d i s c h a r g e p r o t e c t i o n c i r c u i tautomatically shuts off the battery circuit whenbattery voltage is low.* The built-in charging circuit permits the batteryto be charged while the oscilloscope is in use.1
