2. On the Vector Signal Analyzer:

a. Press the

Frequency key.

b. Set center frequency to 836.52 MHz.

c. Set the span to 2.6 MHz.

d. Press the

Instrument Mode key

e. Press the

Digital Demodulation (F4) key

f. Press the

Demodulation Setup (F5) key

g. Press the

Demodulation Format (F1) key

h. Press the

Standard Setups (F7) key.

i. Press the

3. Use the following equation to calculate rho.

4. Compare and record the rho calculated in Table 9-27, “CDMA

Generator Modulation Accuracy Test 26 Record,” on page 278.

5. Set the CDMA GEN frequency on the Test Set and change the center

frequency on the Vector Signal Analyzer to the 1851.25 MHz.

6. Calculate rho (using the above equation), and record the result (rho)

in Table 9-27, “CDMA Generator Modulation Accuracy Test 26

Record,” on page 278.
