2.
Call niFgen ni5433 Flatness Cal Configure.
3.
Call niFgen ni5433 Flatness Cal Adjust with the following settings:
•
Measured Power (dBm)
: 0 dBm
4.
Connect the power sensor with the SMA (m)-to-N (f) adapter attached to CH 0 of the
PXIe-5413.
5.
Call niFgen ni5433 Flatness Cal Configure to obtain the
Current Configuration
and
Next Configuration
outputs.
6.
Configure the power sensor with the following settings:
•
Auto range
: Enabled
•
Maximum noise ratio
: 0.005 dB
•
Power measurement
: Continuous average
•
Path selection
: Automatic
•
Averaging
: Automatic
•
Aperture
: 20 ms
•
Timeout
: 10 s
•
Frequency
: Frequency returned by the
Current Configuration
output of niFgen
ni5433 Flatness Cal Configure in the previous step
7.
Wait 1 second for settling.
8.
Measure the power of the signal using the power sensor.
9.
Call niFgen ni5433 Flatness Cal Adjust with the following settings:
•
Measured Power (dBm)
: Power of the waveform present on CH 0 of the
PXIe-5413 and measured by the power sensor in the previous step in dBm
10. If the
Next Configuration
output of niFgen ni5433 Flatness Cal Configure obtained in
step 5 returns CH 0, repeat steps 5 through 9. If the
Next Configuration
output of niFgen
ni5433 Flatness Cal Configure obtained in step 5 returns CH 1, continue to step 11.
11. Connect the SMA (m)-to-N (f) adapter and power sensor assembly to CH 1 of the
PXIe-5413.
12. Call niFgen ni5433 Flatness Cal Configure to obtain the
Current Configuration
output.
13. Configure the power sensor with the following settings:
•
Auto range
: Enabled
•
Maximum noise ratio
: 0.005 dB
•
Power measurement
: Continuous average
•
Path selection
: Automatic

Aperture
: 20 ms
•
Timeout
: 10 s
•
Frequency
: Frequency returned by the
Current Configuration
output of niFgen
ni5433 Flatness Cal Configure in the previous step
14. Wait 1 second for settling.
15. Measure the power of the signal using the power sensor.
