Is it possible to read the peak-to-peak TKTDS1K2K driver directly?

[pathman]

I am using a TDS 2014 osciloscope , It take seven seconds to read all wave form (2500 points). Is it posible to read directly the peak to peak value without read wave-form vi ?
My task is time dependent , I want to read within a few milliseconds,
thank you .

A quick look at the driver shows that there's a function called TKTDS1K2K Measurement Setting and one called TKTDS1K2K Read Instrument Data. I don't have the instrument to check how fast it will read, but it's got to be faster than transferring the whole waveform.

I used both TKTDS1K2K Measurement Setting and TKTDS1K2K Read Instrument Data vi. Scope show the measurement value "1.02? " , "1.02?" mean NaN ,but I got the value through Read Instrument Data 1.02 without error message. expected value is NaN .
Measurement vaues for peak-to-peak, Max ...
some of the examples
ScopeValue ReadInstrumentData expectedValue
1.02? 1.02 NaN
2.03? 2.03 NaN
10.04 10.04 10.04
100.02 100.02 100.02

The function does nothing to check for the "?" symbol. It just converts to a DBL and the ? gets dropped. You can modify the VI to return NaN. I'd be curious to know what condition causes the scope to think a peak-to-peak measurment is NaN.

Thank you for your quick response
I want to check peak-to-peak to control volts/meter.
If I get the NaN value then I can reduce the Volts/meter value until I get a number value , then I can display whole wave form.
If I display whole wave form it will take more than 7 seconds per value.
If you have any aternative , please answer to me.
thank you
