Tektronix 314 - How to Measure Ime; Risetime

d. Adjusted deflection factor for any setting of the VOLTS/
DIV switch equals the VOLTS/DIV switch setting multiplied
by the conversion factor.
c. Divide the apparent time interval by the SWEEP MAG
switch setting to obtain the actual time interval.
e. The peak-to-peak amplitude of any signal compared to
this reference is measured as follows:
Set the VOLTS/DIV switch to provide sufficient de 
flection to make a measurement. Do not move the
VARIABLE control setting.
Signal Amplitude = Adjusted Deflection Factor x
Signal Deflection (in div).
HOW TO MEASURE TIME
The time base is accurately calibrated; therefore, any hori 
zontal graticule distance represents time. Time between two
or more events is measured directly on the graticule as
follows:
a. Using the graticule, measure the horizontal distance be 
tween two events.
b. Multiply the distance measured by the TIME/DIV switch
setting to obtain the apparent time interval. The TIME/DIV
VARIABLE control must be in the CAL position.
Risetime
Risetime is defined as the time between the 10% vertical
amplitude point and the 90% vertical amplitude point. See
Figure 13.
