37. On the UUT, enable the REF FREQUENCY OUTPUT at 10 MHz and set the
UUT as follows:
Frequency 10 MHz
Level -75 dBm
Output OPER
38. Allow the Measuring Receiver to tune the input signal, and then set the
controls to measure RF level, relative (dB) to the current input level.
39. Without changing any Measuring Receiver settings, set the UUT to the next
amplitude listed in Table 3-14 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).
40. Calculate the UUT output P
out
= P
-75
+ P
rel
. Check that the value of P
out
is
within the tolerance shown in Table 3-14.
41. Repeat steps 39 and 40 for each amplitude listed in Table 3-14 for this
frequency.
42. Return the UUT output to -75 dBm, set the UUT frequency to the next
frequency listed in Table 3-14 and repeat steps 39 through 42.
43. Set the UUT to STBY.
