VXi VT1422A 사용자 설명서

From the Panels menu, select Main Panel, then enter the following 
commands on the Enter Command line in the Interactive Communications 
box to test the 100 Hz filter. Note that it is necessary to change the channel 
number (10000) in these commands depending on the channel being testing:

samp:tim min

trig:sour tim;tim 400e-6;count 2000

rout:seq:def (@0(10000))

func:volt (@10000)

inp:filt:freq 100,(@10000);stat on,(@10000)

init

data:fifo?

This should display a value between about 85 and 100, which is the 
computed bandwidth of the 100 Hz filter. This value should be considered 
only as an approximate value given the limited resolution on the 
measurement.

To test the 10 Hz filter, now enter the following commands (again, modify 
the channel number as appropriate):

inp:filt:freq 10,(@10000)

init

data:fifo?

This should display a value between about 9 and 10, which is the 
approximate bandwidth of the 10 Hz filter.

To test the 2 Hz filter, now enter the following commands (again, modify the 
channel number as appropriate):

inp:filt:freq 2,(@10000)

init

data:fifo?

This should display a value of approximately 1.9 to 2.2.

Finally, to test the 20 kHz filter, enter (again, modify the channel number as 
appropriate):

inp:filt:stat off,(@10000)

init

data:fifo?

This should display a value greater than 1000.

Use the Digital Multimeter to verify that the VT1531A outputs transition 
from 0 V to 5 V after the INITiate:IMMediate command is sent.
