Table A-4: Procedure to Test MCC–DO Rho
Step Action
10 Enable the modem on MCC–DO card by entering the following command:
enable <modem number>
where:
S <modem number> is the modem selected in step 10.
11 To generate a pattern, enter the following command:
fl_pattern 3
12 On the Agilent E4406, set the Mod Accuracy (composite Rho) measurement:
S Press Measure button
S Press More button until Mod Accuracy (composite Rho) option is displayed
S Select Mod Accuracy (composite Rho)
S Press Meas Setup button
S Press More button until Trig Source option is displayed
S Press Trig Source key and select Ext Rear option
S Press More button until Advanced option is displayed
S Select Advanced option
S If Chip Rate option is set to a value different than 1.228800, select Chip Rate and set it to
1.228800
S Select Active Set Th option to a value calculated using the following formula:
– xcvr_gain – cable_loss – 2dB
S To set appropriate frequency value, press Frequency and enter the value calculated according to the
following formula:
– <tx_base_band_value> + 0.05*<chan_no> [MHz]
13 Read the value of the Rho. Rho normalized cross coefficient ( ò ) is greater than 0.912
MCC–DO Packet Error Rate
The PER test verifies PER (Packet Error Rate) of traffic channels of an
XCVR carrier keyed up at a specific frequency per the current CDF file.
The XCVR is keyed to generate a CDMA carrier (with pilot channel
element only) of the correct level.
The calibrated communications test set measures the all zero long code
and verifies that the PER is not greater than 1 percent. A total number of
packets to be received is dependent on Rate Set chosen.
PER Prerequisites
To perform the following test, the Agilent E4432B Signal Generator
must have the following installed:
A
