Performance Test 3
3-63
20. On the UUT enable the REF FREQUENCY OUTPUT at 10 MHz and set the
UUT as follows:
Frequency 100 kHz
Level -7 dBm
Output OPER
21. Allow the Spectrum Analyzer/Measuring Receiver to tune the input signal,
and then set the controls to measure RF level, relative (dB) to the current
input level.
22. Without changing any Spectrum Analyzer/Measuring Receiver settings, set
the UUT to the next amplitude listed in Table 3-26 for this frequency. Allow
the Measuring Receiver reading to stabilize and record the reading as P
rel
.
(Note that P
rel
will be a negative number in dB).
23. Calculate the UUT output P
out
= P
-7
+ P
rel
. Check that the value of P
out
is
consistent with the typical performance shown in part A of Table 3-26.
24. Repeat steps 22 and 23 for each amplitude listed in part A of Table 3-26 for
this frequency.
25. Return the UUT output to -7 dBm, set the UUT frequency to the next
frequency listed in part A of Table 3-26, and repeat steps 21 through 25.
26. Set the UUT to 100 kHz at -37 dBm. Repeat steps 21 through 26 for the
points listed in part B of Table 3-27 using the calculation P
out
= P
-37
+ P
rel
in
step 23.
27. Set the UUT to STBY.
