4-19 Phase Mod - Max Deviation Tests
Performance Verification
4-56
PN: 10370-10386 Rev. B
MG362x1A MM
At each RF frequency, test max phase deviation for each of the mod rates and conditions in the Max
Phase Deviation Table.
2.
Set external function generator Frequency = mod rate from the table.
3.
Set MG362x1A Ext Phase Mod Sensitivity to the table value for the current mod rate.
4.
Wait 25 msec for PLL. Set
Φ
M ON. Wait 60 msec for PLL.
5.
Check PLL lock status. If unlocked:
6.
Report “Lock Fail” for the current mod rate. Set
Φ
M OFF.
7.
Go to step
.
8.
Wait approx 1sec for FSWP to complete a full cycle of RMS Phase Deviation measurement.
9.
Note RMS Phase Deviation shown in the FSWP “Summary” window.
10.
Calculate Peak Deviation = 1.414*( RMS deviation). Record this value for the current mod rate.
11.
If calculated Peak Deviation is < (Test Limit value in the table for the current mod rate), record “Fail” for
the current mod rate.
12.
If current mod rate is < 7 MHz, pick the next mod rate from
and go to
.
13.
If RF < 20 GHz, set DUT and FSWP to next RF freq (from list in
, and a mod rate of
10 kHz.
14.
If no Fails have been reported for any of the mod rates at any of the RF test frequencies, indicate “Pass”
for the overall test.
