Selects the waveform file to be used for playback on the selected baseband generator channel. If an Agilent Signal Studio waveform is selected, its header information is also extracted from the file and used for several parameters, such as Sample Rate, Runtime Scaling, and Baseband Frequency Offset.
The PXB defaults to the waveform file default1.bin in the folder: C:\<Program Files for Win XP><Program Files (x86) for Win 7>\Agilent\PXB\FactoryDefaultWaveforms
This folder contains several waveform files that are saved in the PXB. Each of these waveform files is described in Factory Default Waveform Files.
You can choose from any of the factory default waveform files or you can navigate to a waveform file that you have previously saved in the PXB using the Open File dialog box.
Choices: Two's Complement,
Offset Binary
Default Value: Two's Complement
Dependency: Displayed only when Waveform Source Name is not selecting an
Agilent Signal Studio waveform
Displays and sets the binary format for the selected waveform file. When a waveform file is played, the waveform data is read from the file and scaled to 16 bits of resolution so that:
+1 = 32767
0 = 0
–1 = –32767
The binary file contains 16-bit data stored in Big Endian format, alternating the I and Q data as shown.
I1 Q1 I2 Q2 I3 Q3 ... I14 Q14 I15 Q15 I16 Q16
Twos Complement
Sets the numeric format to a two’s complement
representation of the waveform file's data values.
Offset Binary
Sets the numeric format to an offset binary
representation of the waveform file's data values.
Range: 256 to 9.223 X 1018
samples
Default Value: 5000 samples
Displays the number of samples in the selected waveform file. This parameter is read-only.
Range: 0 to 2,147,483,647 (231
– 1) Samples
Default Value: 0 (continuous play)
Displays the number of times the selected waveform file is played. If this parameter is set to 0 (zero), the waveform file is played continuously.
Choices: Hold Last Value, Zero
Default Value: Hold Last Value
Sets the value of the state that the output is set at when the waveform file stops playing.
Hold Last Value
Holds the last I and Q sample value (including the markers) on the output
until the next waveform is played.
Zero
Sets the output value to zero when the waveform has completed playing.
Choices: N5106A Native Format, N5110B Format
Default Value: N5106A Native Format
Selects the bit order for the waveform file.
N5106A Native Format
Plays the waveform file reading the bytes in sequential
order (Big Endian). This is the native N5106A PXB format. Little Endian
and Big Endian (Byte Order) for more information.
N5110B Format
plays the waveform file swapping
every other byte position (Little Endian). This is the format used with Agilent N5110B Baseband Studio systems. Little Endian
and Big Endian (Byte Order) for more information.
