Applications
EXAMPLE. In Figure 3-1, the measured peak-to-peak vertical
deflection is 4.4 divisions using a 10X attenuator probe with the
VOLTS/DIV switch set to 5V (10X PROBE).
Substituting the given values:
Vp-p = 4.4 div X 5 V/div = 22 V.
Instantaneous Voltage
To measure the instantaneous voltage level at a given point on a
waveform, referred to ground, use the following procedure;
1. Apply the signal to either the CHI or the CH2 input connec¬
tor and set the VERTICAL MODE selector to the channel
used.
2. Verify that the VOLTS/DIV variable control is in the CAL
detent and set input coupling to GND.
3. Vertically position the trace to the center horizontal graticule
line. This establishes the ground reference location,
NOTE
If the measurements are to be made relative to a
voltage level other than ground, set the input cou¬
pling switch to DC and apply the reference voltage
to the input connector. Then position the trace to
the horizontal reference line.
4. Set the input coupling control to DC. Points on the
waveform above the ground reference location are positive;
points below are negative.
NOTE
if using Channel 2, ensure that the center VERTI¬
CAL MODE selector (NORM, CH 2 INVERT), is set
to NORM.
5. If necessary, repeat Step 3 using a different horizontal
ground reference line that allows the waveform in Step 4 to
be displayed on screen.
