Version 04

Service Manual SM300: 1147.1652.00

Instrument Part No SM300: 1147.1498.03

2.4.9 Frequency Modulation

2.4.9.1 FM Deviation Setting

Test setup

Test setup 1 with modulation analyzer

Settings on SM300

LEVEL 0 dBm

FREQ 1 GHz

MODULATION FM DEVIATION 100 kHz
LFGenFreq 1 kHz

Setting on
modulation analyzer

Demodulation: FM

Detector: peak detector

Filter: 20 Hz to 23 kHz

Measurement

Read frequency deviation on modulation analyzer

2.4.9.2 FM Frequency Response

Test setup

Test setup 1 with modulation analyzer

Settings on SM300

LEVEL 0 dBm

FREQ 1 GHz

Deviation 50 kHz

Setting on
modulation analyzer

Demodulation: FM

Detector: peak detector

Measurement

The modulation frequency response is determined by varying the generator
frequency of the internal LF generator in the FM menu from 20 Hz to 20 kHz.
It is obtained from the difference between the lowest and highest measured
deviation.

2.4.9.3 FM Distortion

Test setup

Test setup 1 with modulation analyzer

Settings on SM300

LEVEL 0 dBm

FREQ 777 MHz

Deviation 50 kHz
LFGenFreq 1 kHz

Setting on
modulation analyzer

Demodulation: FM

Detector: peak detector

Audio: distortion

Measurement

Read distortion on modulation analyzer.

2.4.9.4 Output Reflection Coefficient

Test setup

Test setup 1 (use SWR bridge instead of the block mixer, preamplifier; the
scope is not used).
