3. Spectrum Analyzer Frequency Accuracy

The following test can be used to verify the CW frequency accuracy of the Spectrum Master.
a. Equipment Required:
· Anritsu MG3692A Synthesized Signal Source, with option 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
b. Procedure:
1. Connect the 10 MHz reference source to the Anritsu MG3692A Synthesized Signal Source.
2. Connect the output of the source to the RF Input of the Spectrum Master.
3. Connect the external power supply (Anritsu part number 40-168) to the Spectrum Master.
4. Press and hold the
ter. (This sets the instrument to the factory preset state.)
5. Turn on the 10 MHz reference source and the Anritsu MG3692A Synthesized Signal Source.
6. Set the MG3692A output to 2000 MHz CW, with an RF output level of 0 dBm.
NOTE: Before continuing, allow a 30-minute warm up for the internal circuitry to stabilize.
