    2-3-3. Probe Adjustment When applying the external signal to measure using oscilloscope, use probe. The applied waveform is displayed on the CRT of oscilloscope. The product has two points : × 1 (direct connection) and × 10 (attenuation). At × 10 point, the input impedance of oscilloscope increases, which attenuates the input signal by 1/10.

  • Page 31: Measurement Applications

    2-4. MEASUREMENT APPLICATIONS This section contains instructions for using your Oscilloscope for specific measurement procedures. However, this is but a small sampling of the many applications possible for this oscilloscope. These particular applications were selected to demonstrate certain controls and features not fully covered in BASIC OPERATING PROCEDURES, to clarify certain operations by example, or for their importance and universality.
  • Page 32 d. Count the number of division from the graticule line touching the negative signal peaks to the intersection of the positive signal peak with the central vertical graticule line. Multiply this number by the VOLTS/DIV switch setting to get the peak-to-peak voltage of the waveform.
  • Page 33 d. Flip the AC/DC/GND switch to DC. The polarity of all points above the ground-reference line is positive ; all points below the ground-reference line are negative. <Caution> Make certain the waveform is not riding on a high-amplitude DC voltage before flipping the AC/DC/GND switch. e.
  • Page 34 e. Count the number of horizontal graticule divisions between the Step ‘d’ graticule line and the second measurement point. Measure to a tenth a major division. Note that each minor division of the central horizontal graticule line is 0.2 major division.
  • Page 35 2-4-3. Frequency measurement When a precise determination of frequency is needed, a frequency counter is obviously the first choice. A counter can be connected to the CH1 OUTPUT connector for convenience when both oscilloscope and frequency counter are used. However, and oscilloscope alone can be used to measure frequency when a frequency counter is not available, or modulation and/or noise makes a counter unusable.
  • Page 36 2-4-4. Phase difference measurements Phase difference in phase angle between two signals can be measured using the dual- trace feature of the oscilloscope, or by operation the oscilloscope in the X-Y mode. Dual-trace Method This method works with any type of waveform. In fact, it will often work even if different waveforms are being compared.
  • Page 37 The horizontal distance between corresponding points on the waveform is the phase difference. For example, the phase difference is 1.2 major divisions, or 60°. If the phase difference is less than 50°(one major division) it is possible to conduct a finer measurement with 10 × magnification, each major division is 5° and each minor divison is 1°.
  • Page 38 Precisely center the trace horizontally with the Horizontal POSITION control. Count the number of divisions along the central vertical graticule line. You can now shift the trace vertically with CH2 POSITION control to a major division line for easier counting. The phase difference (angle) between the two signals is equal to the arcsine of dimension A, B (the Step ‘g’...
  • Page 39 b. Adjust the A TIME/DIV switch to display about 2 cycles of the pulse. Make certain the A VARIABLE control is rotated fully clockwise and pushed in. c. Center the pulse vertically with the channel 1 Vertical Position control. d. Adjust the channel VOLTS/DIV switch to make the positive pulse peak exceed the 100% graticule line, and the negative pulse peak exceed the 0% line, rotate the VARIABEL control counterclockwise until the positive and negative pulse peaks rest exactly on the 100% and 0% graticule line.

    Maintenance routines performable by the operator are listed in this section. More advanced routines (i.e., procedures involving repairs of adjustments within the instrument) should be referred to EZ service personnel. 3-1. CLEANING If the outside of the case becomes dirty or stained, carefully wipe out the soiled surface with a cloth moistened with detergent, then wipe out the cleaned surface with a dry cloth.
