acquire data from oscilloscope DPO2024

[ajha]

I am trying to acquire data from oscilloscope DPO2024 using labview. I am able to do so, but my vi file works only for channel 1. Other than channel 1, it do not work and instead, it changes the setting of oscilloscope as well. Find the vi files attached.

Any help is much appreciated.

You need to wire the channel into the Read Waveform.  It defaults to channel 1 if unwired.

I am trying to acquire signals from multiple channel and view them in the same graph. I tried but failed each time. Any help will be appreciated.

1.  You only need to initialize the scope once.  You not need to branch the VISA Resource wire.  Call the Initialize, Setup Channel 1, and then Setup Channel 2 all chained together.

2.  Use Build Array to create your array of channels.  The Merge Signals is a completely backwards way to do it.

3.  You only need to close the instrument once.
