preamble tds3014 problem

I have been using LabVIEW 8.0 to acquire waveform from a TDS3014B oscilloscope.
The LabVIEW program was working .
Recently I got another TDS3014B oscilloscope (its firmware is the same as my first TDS3014B).
However, the preamble acquired from the second oscilloscope is different from the first one.
The preamble string from the second oscilloscope does not show NR_P, XIN, YOF, YZE, ....
It is following :

2;16;BIN;RI;MSB;10000;"Ch1, DC coupling, 1.0E-1 V/div, 4.0E-4 s/div, 10000 points, Sample mode";Y;4.0E-7;0;-4.0E-4;"s";1.5625E-5;0.0E0;0.0E0;

So I cannot get the offset and scale of the acquired waveform.
Anyone can give me suggestion? Thanks.

Hey,
According to what you have mentioned I understand that your LabVIEW program is working fine, only the preamble string that you are receiving is different. Well it would be better if you can send me the NI Spy capture screen shots. Click on the link to perform a good NI-Spy Capture . I will look into that and suggest you why is that happening.

Are the HEADer & VERBose commands set the same in both scopes?

Thank you for all your help, wd8ivl and Nikhil A.

I got the the following preamble that is what I want by turning OFF the VERBose.

:WFMP:BYT_N 2;BIT_N 16;ENC BIN;BN_F RI;BYT_O MSB;NR_P 10000;WFI "Ch1, DC coupling, 1.0E0 V/div, 2.0E-4 s/div, 10000 points, Sample mode";PT_F Y;XIN 2.0E-7;PT_O 0;XZE -2.0E-4;XUN "s";YMU 1.5625E-4;YZE 0.0E0;YOF 2.56E2;YUN "V";:CURV #520000

You should try the instrument driver:

If you are opposed to using the driver, you can still look at the block diagrams to see how the data transfer is handled.
