Please clarify the below.
When i tried to capture a signal generated from LWS data acquisition system on TDS2002B scope interfaced through a 50 Ohm bnc cable, the readings in the scope were different than that of data acquisition systems. Scope is brand new, calibrated.
settings done: in Data Acquisition system - Generate - 2khz signal @ 2Vpp for 60seconds.
Redings on TDS2002b : - 3.5KHz and 4Vpp.

1)Should there be a procedure to capture from data acquisition system? .
2)First of all i want to know is it possible to capture the data from a data acquisition systems, where you will be commanding through software to generate. ? i am correct or not?.
Pls provide technical points/ clarifications.
Thanks
