Second Harmonic Distortion Test
The following test can be used to verify the combined input related spurious response of the FCN4760
Frequency Converter and Spectrum Master.
c. Equipment Required:
· Anritsu MG3692A Synthesized Signal Source with options 2A, 4 and 15A, or equivalent
· Anritsu 34RSN50 50 ohm adapter or equivalent
· Anritsu 15NNF50-1.5C RF Coaxial Cable or equivalent
· 10 MHz Reference Standard
· BNC male to BNC male coaxial cable
d. Procedure:
1. Connect the 10 MHz reference source to the Anritsu MG3692A Synthesized Signal Source.
2. Connect the output of the FCN4760 to the Spectrum Analyzer RF In port of the Spectrum Mas-
ter.
3. Connect the output of the source to the FCN4760 RF Input with the coaxial cable.
4. Connect the external power supply (Anritsu part number 40-168) to the Spectrum Master.
5. On the Spectrum Master, press and hold the
turn on the Spectrum Master. (This sets the instrument to the factory preset state.)
6. Turn on the 10 MHz reference source and the Anritsu MG3692A Synthesized Signal Source.
7. Set the MG3692A output to 5 GHz CW, with an RF output level of –45 dBm.
NOTE: Before continuing, allow a 30-minute warm up for the internal circuitry to stabilize.
