Rohde & Schwarz FSP7 - Checking Amplitude Modulation

R&S FSP Performance Test
1166.4556.82 1.25 E-1
Checking Amplitude Modulation
Test equipment:
- Arbitrary waveform generator (refer to "Measurement Equipment",
i
tem 16)
- Spectrum analyzer (refer to "Measurement Equipment", item 15)
- 2 voltmeters (refer to "Measurement Equipment", item 17)
- 2 BNC T pieces
Test setup with R&S ADS:  Apply the I and Q outputs of ADS to the I and Q inputs of the
analyzer. Check the ADS voltages in parallel via T pieces.
 Connect spectrum analyzer to the TG output.
Test setup with 33220A:  Apply the outputs of 33220A to the I and Q inputs of the analyzer.
Check the 33220A voltages in parallel via T pieces.
Synchronize the 33220A via Option 001.
 Connect spectrum analyzer to the TG output.
Generator settings:
 AC voltage: V(pp) = 1 V ± 10 mV
Frequency: 1 MHz
Spectrum analyzer settings:
- [ FREQUENCY : 1 GHz ]
- [ SPAN : 10 MHz ]
- [ REF : REF LEVEL : 0 dBm ]
R&S FSP settings:
- [ FREQUENCY : 1 GHz ]
- [ SPAN : 0 MHz ]
- [ REF : REF LEVEL : 0 dBm ]
- [ NETWORK : SOURCE POWER -6 dBm ]
- [ MODULATION EXT AM ]
Measurement:  Determine the level spacing between the carrier signal at 1 GHz
and the modulation lines at 1 GHz ± 1 MHz.
