Tektronix 314 Manual

See Figure 1 5. Each graticule div now represents 45° of the
displayed 360° (8 div).
g. Measure the horizontal distance between corresponding
points on the display. Multiply the measured distance in
div by 45°/div to obtain the phase difference.
HOW TO MAKE HIGH-RESOLUTION
PHASE MEASUREMENTS
More accurate dual-trace measurement can be made by
increasing the sweep rate. Switch SWEEP MAG to X10
without changing the TIME/DIV VARIABLE (as set in the
preceding description). The magnified sweep rate is the
sweep rate from the preceding description divided by 10
(X10 SWEEP MAG). The new sweep rate is 4.5°/horizontal
div.
HOW TO MEASURE
COMMON-MODE REJECTION
The ADD function of the 314 can be used to display signals
that contain undesirable components as follows:
a. Connect the signal containing both the desired signal and
the undesired signal to CH 1 VERT INPUT connector.
Connect a signal identical to the unwanted portion of
CH 1 signal to CH 2 VERT INPUT connector.
