PN: 10370-10386 Rev. B
MG362x1A MM
Test Setup
Connect equipment as shown in
FSWP:
Tab Analog Demod. If “PM Time Domain” window does not appear, then: Meas Config / Display Config
/ drag “PM Time Domain” to screen center. This will replace FM measurement with Phase Mod measurement.
The “Summary” Display will now show Phase Mod results.
Meas Config / Demod BW = 12.5 kHz, Meas Time = 100 msec
Scale Config = 0.1 rad/div.
Demod Config / Demod / AF Coupling = AC, AF HPF = 50 Hz
Trace Config:
Trace 1 Clear/Write, Linear, Smoothing = 1 %.
Trigger button:
Set “PM Offline” as the trigger source.
External Function Generator:
Channel OFF.
MG362x1A:
Int Low Noise Phase Mod mode,
Φ
M OFF, DC Coupled, Deviation = 0.2 rad,
Φ
M ON.
Test Procedure
1.
Set DUT and FSWP RF frequency per the following list, starting at the lowest freq:
2.6 GHz, 5 GHz, 10 GHz, 20 GHz
At each RF frequency, measure phase deviation for each of the mod rates and conditions in the
Measurement Uncertainties and Test Limits Table (
), starting with 1 kHz mod rate.
2.
Set Int Phase Mod Mod Rate = mod rate from the table.
3.
Wait 25 msec for PLL. Set
Φ
M ON. Wait 10 msec for PLL.
4.
Check PLL lock status. If unlocked:
5.
Report “Lock Fail” for the current mod rate. Set
Φ
M OFF.
