Note For more information about the .lvm file format, refer to the LabVIEW Express Measurement File
Specification v. 0.92 at NI Developer Zone. |
| File Name | Description |
|---|
|
fgMode-square.bin | A binary file that contains 16,384 16-bit samples in
little endian format.
The waveform pattern represented in the file is a single period
of a square pattern with a high duty cycle of 20%.
|
| arbMode-Testsignal.bin |
A binary file that contains 50,000 16-bit samples in little endian format. The waveform pattern contains five periods of a sine waveform pattern, 5 periods of a square waveform pattern, 5 periods of a triangular
waveform pattern, 4.5 periods of a sawtooth waveform pattern, and
a stairstep pattern with 10 steps. The length of each step in the
stairstep waveform pattern is equal to the length of ½ period
of the previous pattern. |
| arbMode-sine.lvm | A text-based file containing six waveforms of
400 samples each. The file conforms to the LabVIEW Express Measurement File
Specification v.0.92. Each set of waveform data in this file
represents multiple periods of a sine waveform pattern.
Each line after the header (starting with line 24) is organized
into columns separated by a <TAB> character. The first column is
empty, normally holding the relative time in seconds from the first sample.
The second through seventh columns contain data values whose maximum amplitude
is ±1 V. The last column contains comments. |
| arbMode-square.lvm | A text-based file containing four waveforms of
400 samples each. The file conforms to the LabVIEW Express Measurement File
Specification v. 0.92. Each set of waveform data in this file
represents multiple periods of a square waveform pattern.
Each line after the header (starting with line 24) is organized
into columns separated by a <TAB> character. The first column is
empty, normally holding the relative time in seconds from the first sample.
The second through fifth columns contain data values whose maximum amplitude is ±1 V.
The last column contains comments.
|
| arbMode-triangular.lvm |
A text-based file containing four waveforms of
400 samples each. The file conforms to the LabVIEW Express Measurement File
Specification v. 0.92. Each set of waveform data in this file
represents multiple periods of a triangular waveform pattern.
Each line after the header (starting with line 24) is organized
into columns separated by a <TAB> character. The first column is
empty, normally holding the relative time in seconds from the first sample.
The second through fifth columns contain data values whose maximum amplitude is ±1 V.
The last column contains comments. |
|
arbMode-rampup.lvm | A text-based file containing four waveforms of
400 samples each. The file conforms to the LabVIEW Express Measurement File
Specification v. 0.92. Each set of waveform data in this file
represents multiple periods of a ramp up waveform pattern.
Each line after the header (starting with line 24) is organized
into columns separated by a <TAB> character. The first column is
empty, normally holding the relative time in seconds from the first sample.
The second through fifth columns contain data values whose maximum amplitude is ±1 V.
The last column contains comments. |
| arbMode-rampdown.lvm |
A text-based file containing four waveforms of
400 samples each. The file conforms to the LabVIEW Express Measurement File
Specification v. 0.92. Each set of waveform data in this file
represents multiple periods of a ramp down waveform pattern.
Each line after the header (starting with line 24) is organized
into columns separated by a <TAB> character. The first column is
empty, normally holding the relative time in seconds from the first sample.
The second through fifth columns contain data values whose maximum amplitude is ±1 V.
The last column contains comments. |
| arbMode-noise.lvm |
A text-based file containing 512 samples.
The file conforms to the LabVIEW Express Measurement File
Specification v. 0.92. The data in this file
represent uniform white noise. Each line after the
header (starting with line 24) is organized into columns separated
by a <TAB> character. The first column is empty, normally holding the relative time in seconds from the first sample. The second column
contains a data value whose maximum amplitude is ±1 V.
The last column contains comments. |
| FList_ExampleFile.txt |
Contains a frequency list designed for NI signal generators. The first column in this sequence
represents a frequency to be generated for the amount of time
specified in column two (duration). This frequency list contains
516 entries. The last four entries and the 512th entry are different
from the rest of the list to distinguish the last entry output when
imported into an NI PXI/PCI-5401/5411/NI-5431 signal generator. |
| FSK_ExampleFile.txt |
An example showing how FSK data must be set up to import
it into the FGEN Soft Front Panel. This file contains 138 binary data bits. |
