A.1.3 Reading Measurement Values - Fluke CombiScope PM3370B User Manual

APPLICATION PROGRAM EXAMPLES

A.1.3 Reading measurement values

In the following example measurement values are read into the computer as
calculated by the front panel MEAS1 and MEAS2 features during a single-shot
measurement.
Application summary:
•
Configure for measuring AC-RMS by sending: CONFigure:AC
and initiate a single-shot by sending:
•
Then stop program execution to let you select the following MEAS values via
the front panel:
> MEAS1-volt-dc
> MEAS2-time-frequency
•
After printing the read measurement values, stop program execution again to
let you select the following MEAS values via the front panel:
> MEAS1-volt-rms
> MEAS2-time-period
Application program:
Note: The program is supplied on floppy under file name EXAPPA13.BAS.
A.2 Acquiring Waveform Traces
In the following example a channel 1 trace of maximum 4096 samples of 1 or 2
bytes is read, converted to voltage values, and printed in portions of 90 samples.
Application summary:
•
Read the channel 1 trace by sending:
•
Convert the binary trace samples to integer values (refer to section 3.4.3.1
and 3.4.3.2).
•
Read the peak-to-peak range by sending: SENSe:VOLTage:RANGe:PTPeak?
•
Read the offset voltage by sending:
•
Convert the integer values to voltage values (refer to section 3.4.3.3) and print
them in portions of 90 samples.
Application program:
Note: The program is supplied on floppy under file name EXAPPA2.BAS.
