  • SENSITIVITY : 5mV/div to 2oV/div. 12 calibrated steps in 1-2-5 sequence.
  • ACCURACY : ± 3%.
  • BANDWIDTH :

DC-2oMHz (- 3dB) DC coupled

10Hz - 20 MHz (- 3dB) AC coupled.

  • RISE TIME : 17.5nsec.
  • INPUT COUPLING : DC/AC/gnd, switch selectable.
  • INPUT IMPEDANCE : 1MΩ// 25pF.

  • ACCURACY : ±3%

     

  1. TRIGGERING:
  • AUTO/NORMAL : Trigger level continuously adjustable on the positive or. negative slope of the triggered waveform. Level adjustable over 8 divisions both in auto/normal mode.
  • SOURCE : INTERNAL from either channels, LINE or EXTERNAL.
  • TV : Full TV trigger facility for TV-V and TV-H.
  • COUPLING : DC/AC/HF Reject.

  • SLOPE : +ve or –ve

     

  1. TRIGGER SENSITIVITY
  • INTERNAL

(a) AUTO (ALT MODE) : 0.5 div, 30Hz to 20MHz. AUTO (CHOP MODE) : 0.5 div,. 3OHz to lokHz.

(b) NORMAL : 0.5 div, 10Hz to 20MHz AC coupled.

  • EXTERNAL

(a) AUTO : 0.8V p-p, 30Hz to 20MHz, AC/DC coupled.

(b) NORMAL : 0.8V p-p, 3Hz to 2oMHz, DC coupled.

 

  1. HORIZONTAL AMPLIFIER
  • INPUT : Via. CH2.
  • BANDWIDTH : DC 1MHz (- 3dB).
  • SENSITIVITY : Same as CH2.
  • INPUT IMPEDANCE : 1M ohms // 25pF.

  • MAXIMUM INPUT : 400V (DC + peak AC)\

     

  1. CALIBRATION OUTPUT:  200mV p-p ± 2% square wave at 1kHz approx. can be used 10:1 probe compensation.

     

  2. CATHODE RAY TUBE: 140 mm flat faced monoaccelerator.

  • ACCELERATING POETNTIAL : 2KV
  • SCREEN TYPE : GH (P- 43 phosphor).
  • GRATICULE : Internal 10 X 8 cm with % calibration.

Applications of CRO:

  1. Television: A CRT is used along with sweep circuits.
  2. Radar: A CRT screen is used to provide visual displays.
  3. To measure voltage or current, the drop across a resistor is measured.
  4. To study waveforms: A visual display is seen.

  5. Measurement of frequency and phase angle.

     

Applications of DSO:

  1. It can be used to measure a.c as well as d.c voltages and currents.
  2. It can be used to measure frequency, time period ,time interval between two signals and phase for periodic as well as non-periodic signals.
  3. It can be used to observe V-I characteristics of diodes and transistors.
  4. It is possible to add and subtract waveforms in modern DSO.
  5. The signals can also be integrated and differentiated.
