Chapter 4 Performance Test
4-4
(4) Test Procedure
1. Turn on the power switch on the front panel and then wait until
the internal temperature stabilizes.
2. Input the 10 MHz reference signal output from the frequency
standard device to the Reference Input connector of the vector
signal generator.
3. Input the 10 MHz reference signal output from the signal
generator to the Reference Input connector.
4. Press
.
5. Press
(Preset) to initialize.
6. Press
.
7. Press
(SIGANA All) to perform calibration.
8. Press
(Close).
9. Set as follows for the signal generator.
● Continuous wave (CW) output
● Frequency: 100 kHz
● Level: –15 dBm
10. Set as follows for the equipment.
