acquire sine waveform from agilent

[nomade42k]

Hi guys!!!!

I have Labview 8, and I am trying to acquire and graph a sine waveform from a Signal Generator (Agilent 33220A).  I have a BNC2110 instrument connected to my pc, to connect the BNC cable from signal generator.  Well, I dont want to use a Express instrument, and I have used the "Acq&Graph Voltaje-Ext Clk.vi"  and when I want to make the acquisition, i received the following error:

Possible reason(s):

Measurements: Some or all of the samples requested have not yet been acquired.

To wait for the samples to become available use a longer read timeout or read later in your program. To make the samples available sooner, increase the sample rate. If your task uses a start trigger,  make sure that your start trigger is configured correctly. It is also possible that you configured the task for external timing, and no clock was supplied. If this is the case, supply an external clock.

Property: RelativeTo
Corresponding Value: Current Read Position

Property: Offset
Corresponding Value:


Task Name: _unnamedTask

The frecuency of the sine waveform is 100Hz and the amplitude is 100mV set in the signal generator.  I use the AI0 in the BNC2110

Anyone does have some idea which happen??

thanks guys

Sounds to me that you need to read the error explanation. You are using the external clk option so like the message says, is there an external clock that you are providing? If not, why would you use this example?
