•
I
Set the Measuring Receiver to make relative level measurements to the -107
f.
dBm signal applied.
g. Disconnect the sensor from the UUT, and terminate the UUT RF OUTPUT
I
with the Type�N Termination.
h. Connect the two�turn loop to the Measuring Receiver sensor.
I
i. Program the UUT to +13 dBm.
J.
Verify the instrument leakage is less than -107 dBm (I 1N) as indicated by the
I
Measuring Receiver by moving the Two-Turn Loop over the UUT surface at a
distance of one inch from the UUT.
k. Repeat steps d through j at 550 MHz, 850 MHz, and 1050 MHz.
I
4A-1 1 . HARMONIC AND SPURIOUS TEST
Using a spectrum Analyzer, the level of the harmonic and spurious signals are compared
I
to the desired signal at various programmed frequencies.
REQUIREMENTS
I
RF harmonics <-30 dBc; spurious (non-harmonic) <-60 dBc for offsets >10 kHz,
frequency > O. I MHz.
TEST EQUIPMENT
I
RF Spectrum Analyzer
PROCEDURE
I
a. Connect the UUT RF OUTPUT to the Spectrum Analyzer input.
b. Program the UUT to [RCL] [9][8]. Then program the Generator to + 13 dBm.
•
c. Program the UUT to 0.4 MHz.
I
d. Set the Spectrum Analyzer controls to display the UUT output signal and its
harmonics (at least three harmonics wherever possible). Be careful not to
overload the Analyzer input. Overloading the Analyzer causes it to generate
I
harmonics, thus invalidating the test.
e. Verify that all the harmonics are more than 30 dB below the fundamental signal.
f.
I
Repeat steps c through e for UUT frequencies of 50 MHz,
500 MHz, and 750 MHz .
•
g. Program the UUT to 185 MHz.
h. Verify the spur at 245 MHz is < -60 dBc.
I
' ·
Program the UUT to 244 MHz.
J.
Verify the spur at 312 MHz is < -60 dBc.
I
k. Program the UUT to 244.99 MHz, 0 dBm.
