b.
Press the
Sensor Cal
side key to perform zero adjustment and calibra-
tion for the sensor.
5. Perform the flatness measurement for the generator:
a. Modify the hookup: Connect the signal generator output through an N-N
coaxial cable followed by a 10 dB attenuator and an N adapter to the
power sensor input. See Figure 5--2 on page 5--7 again.
b.
Insert a floppy disk to the disk drive of the analyzer for storing the
flatness data.
c. Press the MACRO SETUP key on the front panel.
d. Press Go to page 2 > Create SG Flatness... > All using the side key.
When the measurement has been completed, the flatness data is saved to the
file(s) on the floppy disk:
sgrf1flatness.cal (for the baseband and RF1 band)
sgrf2flatness.cal (for the RF2 band)
sgrf3flatness.cal (for the RF3 band)
6.
Disconnect the hookup:
a.
Remove the floppy disk by pressing the eject button.
b. Turn off the signal generator, power meter, and analyzer.
c. Disconnect the GPIB cables.
