Tektronix 314 Manual

swept-frequency device such as a Spectrum Analyzer. The
external horizontal sensitivity ranges from approximately
20 mV/div (with 1X attenuation and Horizontal Magnifica 
tion on) to 2 V/div (with 10X attenuation and Horizontal
Magnifier off).
The TIME/DIV VARIABLE control provides an additional
10:1 range with which exact adjustment or calibration of
horizontal deflection can be made.
X-Y Displays
One signal (vertical input) viewed with respect to another
(external horizontal input) displays patterns that show
phase and frequency relationships.
a. Set TIME/DIV switch to X1, EXT HORIZ. Press AC
button in and set I NT button to the out position if the sig 
nal has a de component. Press AC and LF REJ buttons in
(EXT DC) if the signal frequency is 30 Hz or less (within
the input frequency limitations).
b. Set the ATTEN switch (X1-X10 on side panel) to the
appropriate position for the voltage level of the external
horizontal signal.
c. Set VOLTS/DIV switch to an appropriate position for
the vertical signal voltage.
d. Apply both X (horizontal) and Y (vertical) signals to
their respective input connectors and observe the display.
NOTE
The vertical and horizontal amplifier character 
istics must be considered in X-Y operation be 
cause of bandwidth and input impedance dif 
ferences. To determine phase difference, apply
the same signal to both inputs and calculate
the difference.
Using External Sweep Voltage
a. Perform the steps under X-Y Displays.
b. Calibrate the horizontal sweep for frequency per div by
adjusting the TIME/DIV VARIABLE control.
SELECTING SWEEP RATE
AND
USE OF THE MAGNIFIER
The sweep rate depends on the desired observation or
measurement to be made. For frequency measurements,
several cycles or events are usually displayed and the time
