8.
Call niFgen ni5433 Timebase Cal Adjust with the following settings:
•
Measured Frequency
: Frequency of the waveform present on the connected
channel of the PXIe-5413 and measured by the oscilloscope in the previous step
9.
If the
Timebase Cal Complete
output of niFgen ni5433 Timebase Cal Adjust returns
FALSE
, repeat steps 5 through 8 until
Timebase Cal Complete
returns
TRUE
.
Note
Timebase adjustment is only required on one channel of the two-channel
PXIe-5413.
Adjusting DC Voltage
Follow this procedure to adjust the DC voltage of the PXIe-5413.
1.
Connect one end of the SMA (m)-to-BNC (m) cable to a channel of the PXIe-5413.
Connect the other end to the double banana plug-to-BNC (f) adapter, and connect the
double banana plug-to-BNC (f) adapter to the HI and LO connectors of the DMM.
Note
DC voltage adjustment can be performed on either channel of the two-
channel PXIe-5413.
2.
Call niFgen ni5433 ADC Cal Initialize with the following settings:
•
Channel
: Channel of the PXIe-5413 connected to the DMM
3.
Call niFgen ni5433 ADC Cal Configure to obtain the
Approximate Voltage Generated
(V
pk-pk
) output.
4.
Wait 1 second for settling.
5.
Configure the DMM with the following settings:
•
Function
: DC Voltage
•
Resolution
: 7.5 digits
•
Aperture time
: 100 ms
•
Number of averages
: 4
•
Auto zero
: Enabled
•
ADC calibration
: Enabled
•
Range
: Range returned by the
Approximate Voltage Generated
(V
pk-pk
) output of
niFgen ni5433 ADC Cal Configure in step 3
6.
Measure the voltage of the signal using the DMM.
7.
Call niFgen ni5433 ADC Cal Adjust with the following settings:
•
Measured Voltage
: Voltage of the waveform present on the connected channel of
the PXIe-5413 and measured by the DMM in the previous step
8.
If the
ADC Cal Complete
output of niFgen ni5433 Timebase Cal Adjust returns
FALSE
,
repeat steps 3 through 7 until
ADC Cal Complete
returns
TRUE
.
Note
DC voltage adjustment is only required on one channel of the two-channel
PXIe-5413.
