Page 10: Points To Be Careful About In Handling And Care
1 Introduction 1-4 Points to be careful about in handling. WHEN TOUCHING LOAD AFTER TURNING OFF HIGH VOLTAGE Make the setting of an output voltage to zero (0). Turn off the HV ON/OFF switch. Check and confirm that the voltage is zero at an output voltmeter of this unit. Turn off the POWER ON/OFF switch. -
Page 11: What To Do Before Calling For Service
1 Introduction 1-5 Additional points to be noted for operation of HV amplifier When using this unit as a high speed and high voltage amplifier(except when DC mode), make sure to have proper connection to make the stray capacity of HV output line as low as possible. - Page 12 1 Introduction Capacitive Load When operated with a capacitive load of more than 100pF (including floating capacity of output cable), the output might oscillate. In such a case put a high voltage resister of 100Ω (0.1μF) to 1kΩ (1000pF) in series to output. Please also note that with capacitive load the bandwidth is limited according to the formula below.
- Page 13 1 Introduction Slew Rate The responsibility of our high speed amplifier is determined with slew rate (SR). The step responsibility of our amplifier is as shown in fig.3. SR = △V/μS In case of output amplitude is smaller the response time become shorter. COR series reach to greater than SR = 30V/μS at maximum.
