8.
Connect the signal generator to the digitizer input as follows for the
current
ChannelList
value:
•
Channel 0 and Channel 1
–
Connect the signal generator directly to the digitizer input for
the channel you are testing.
•
External Trigger
–
Place a 50
Ω
feedthrough terminator on the trigger input of
the digitizer.
–
Connect a cable from the power splitter to the channel 0 input
of the digitizer.
–
Connect a cable from the 50
Ω
feedthrough terminator to the
power splitter.
–
Connect a cable from the output of the signal generator to the
power splitter.
9.
Configure the signal generator to 50
Ω
impedance and output a
10,001,000 Hz sine wave with the
Sine Wave Amplitude
value listed
in Table 15 (NI 5152) or Table 16 (NI 5153/5154) for the current
iteration.
10. Wait the amount of time the manufacturer recommends for the output
of the signal generator to settle.
11. Initiate a waveform acquisition using the niScope Initiate
Acquisition VI.
LabVIEW VI
C/C++ Function Call
Call
niScope_InitiateAcquisition
with the following parameter:
