4-16 FM Harmonic Distortion Tests
MG362x1A MM
PN: 10370-10386 Rev. B
4-51
Test Setup
.
FSWP:
Analog Demod mode, Demod BW 1.6 MHz, Meas Time = 350 msec.
Meas Config: open “FM Time Domain”, “FM Spectrum”, and “Result Summary” windows
Soft key for FM Time Domain window: Set “Scale Config” = 100 kHz/div.
Meas Config: Scale Config/Unit/THD: Select “%”.
Trigger button:
Set “FM Offline” as the trigger source.
External Function Generator :
1 kHz, Channel ON.
MG362x1A:
FM OFF, Low Noise FM mode, Ext FM, DC Coupled, Sensitivity = 300 kHz/V, FM ON.
Test Procedure
1.
Wait 500 msec for FSWP to complete the THD measurement.
For “THD Ext 1 kHz” test, Record “THD” shown in the FSWP “Summary” window.
2.
Skip this pass/fail indication step until a THD spec is published: If THD is
≤
0.80 %, record “Pass” for
“THD Ext 1 kHz”, otherwise record “Fail”.
Int Low Noise FM THD
Measured at 5 GHz RF, 300 kHz FM Deviation, 1 kHz and 50 kHz FM rates. FSWP analog demod “FM
Spectrum” is used for the distortion measurement. FSWP THD spec is 0.1 %. To support a sales spec of 1 %
THD, the test limit should be < (1–0.1 %) = 0.9 %. Use a test limit of 0.80 %.

Int FM rate = 1 kHz, FM ON.
Test Procedure
1.
Wait 500 msec for FSWP to complete the FM measurement.
2.
For “THD Int 1 kHz” test, record “THD” shown in the FSWP “Summary” window. Skip the following
pass/fail indication until a THD spec is published: If THD
≤
0.80 %, record “Pass”, otherwise record
“Fail”.
3.
Set Int FM rate = 50 kHz.
4.
Wait 500 msec for FSWP to complete the FM measurement.
5.
For “THD Int 50 kHz” test, record “THD shown in the FSWP “Summary” window. Skip the following
pass/fail indication until a THD spec is published: If THD is
≤
0.80 %, record “Pass”, otherwise record
“Fail”.
