3. Set the Functio
n G enerator to produce a 1 V DC output. Use the following
steps to set a Tektronix AFG3251:
a. Push the More f
unction button.
b. Push the More Waveform side menu button.
c. Push DC.
d. Push the Top Menu panel button.
e. Push the Amplitude/Level Menu side menu button.
f. Push Offset.
g. Adjust th
e offset voltage to 1V.
h. Push the Output ON button to turn o n the signal output. (The button
glows gr
een.)
4. Set the Multimeter to measure DC volts, autoranging.
5. Connect the Function Generator output to the feedthrough terminator and
BNC-to-Banana Plug adapter on the Multimeter.
6. Enter the measured Terminator Only value in the test record. This value
should be approximately 1 V.
NOTE
. As you add and remove attenuators in this procedure, make sure to keep
them in the same sequence relative to one another and to the cable. When you
first remove an attenuator, whether you remove the one closest to the cable or the
one closest to the DUT, make sure to add/remove that same attenuator in that
same position for the rest of the procedure. If necessary, label the attenuators
to maintain the o rder.
7. Add the first 10X attenuator between the feedthrough terminator and the
coaxial cable, and enter the measured First Attenuator value in the test record.
The value should be approximately 100 mV.
8. Add the second 10X attenuator between the feedthrough terminator and the
coaxial cable, and enter the Second Attenuator measured value in the test
record. The value should be approximately 10 mV.
