Section 6 Peformance Tests
6-22
(4) Test procedures: Spurious measurement
Step Procedure
1. Initialize the MT8801C and signal generator.
2. Set the MT8801C as follows:
RF Input/Output: Main Set it on the Instrument Setup screen.
Using Specification: IS-95A Set on Setup Common Parameter screen.
Reference Level: 0 dBm Set it on the Setup Common Parameter screen.
CDMA Channel: 1 CH Set it on the Setup Common Parameter screen.
3. Set the signal generator including the frequency as follows:
Modulation: On
System: IS-95
Frequency: 825.03 MHz
Output Level: 0 dBm
Simulation Link: Reverse
Filter: SPEC1
Channel: CH1
Channel Assign: Traffic (* “Channel Assigns” of channels 2 to 4 are set to Off.)
Long Code Mask: 00000000000
Frame Type: Type1
Data: USER PTN (0000)
4. Switch the Setup Common Parameter screen to “Spurious Emission” and to “Set Frequency
Table” screen of MT8801C. Set the measurement frequencies from 200 MHz to 3000 MHz at the
200-MHz interval.
5. Return to the Spurious Emission screen and set as “Unit: dB”.
6. Execute “Adjust Range” and then “Measure Single”. Read the measurement result. Check whether
the result is larger than or equal to the specification value (the value of RBW = 30 KHz).
