Queries: STATus:QUEStionable:BERT:NTRansition? STATus:QUEStionable:BERT:PTRansition? Data Questionable BERT Event Register The Data Questionable BERT Event Register latches transition events from the condition register as specified by the transition filters. Event registers are destructive read-only. Reading data from an event register clears the content of that register. Query: STATus:QUEStionable:BERT[:EVENt]? Data Questionable BERT Event Enable Register The Data Questionable BERT Event Enable Register lets you choose which bits in the Data Questionable BERT Event Register set the summary bit (bit 3 of the Data Questionable Condition Register) to 1. Command: STATus:QUEStionable:BERT:ENABle where is the sum of the decimal values of the bits you want to enable Example: Enable bit 11 and bit 2 so that whenever either of those bits are set to 1, the Data Questionable BERT summary bit of the Data Questionable Condition Register is set to 1. Send the command STAT:QUES:BERT:ENAB 520 (2048 + 4). Query: STATus:QUEStionable:BERT:ENABle? Response: Decimal value of the sum of the bits previously enabled with the STATus:QUEStionable:BERT:ENABle command. Agilent N518xA, E8663B, E44x8C, and E82x7D Signal Generators Programming Guide 5 Creating and Downloading Waveform Files NOTE The ability to play externally created waveform data in the signal generator is available only in the N5182A with Option 651, 652 or 654, E4438C ESG Vector Signal Generators with Option 001, 002, 601, or 602, and E8267D PSG Vector Signal Generators with Option 601 or 602. On the Agilent MXG, the internal baseband generator speed upgrade Options 670, 671, and 672 are option upgrades that require Option 651 and 652 to have been loaded at the factory (refer to the Data Sheet for more information). Any references to 651, 652, or 654 are inclusive of 671, 672, and 674. This chapter explains how to create Arb-based waveform data and download it into the signal generator. • “Overview of Downloading and Extracting Waveform Files” on page 184 • “Understanding Waveform Data” on page 185 • “Waveform Structure” on page 193 • “Waveform Phase Continuity” on page 195 • “Waveform Memory” on page 198 • “Commands for Downloading and Extracting Waveform Data” on page 204 • “Creating Waveform Data” on page 212 • “Downloading Waveform Data” on page 218 • “Loading, Playing, and Verifying a Downloaded Waveform” on page 224 • “Using the Download Utilities” on page 227 • “Downloading E443xB Signal Generator Files” on page 228 • “Programming Examples” on page 231 • “Troubleshooting Waveform Files” on page 276 N5181A/82A Agilent N518xA, E8663B, E44x8C, and E82x7D Signal Generators Programming Guide Creating and Downloading Waveform Files Overview of Downloading and Extracting Waveform Files Overview of Downloading and Extracting Waveform Files The signal generator lets you download and extract waveform files. You can create these files either external to the signal generator or by using one of the internal modulation formats (ESG/PSG only). The signal generator also accepts waveforms files created for the earlier E443xB ESG signal generator models. For file extractions, the signal generator encrypts the waveform file information. The exception to encrypted file extraction is user-created I/Q data. The signal generator lets you extract this type of file unencrypted. After extracting a waveform file, you can download it into another Agilent signal generator that has the same option or software license required to play it. Waveform files consist of three items: 1. I/Q data 2. Marker data 3. File header NOTE This order of download is required, as the I/Q data downloads results in the overwriting of all of these three parts of the file. The signal generator automatically creates the marker file and the file header if the two items are not part of the download. In this situation, the signal generator sets the file header information to unspecified (no settings saved) and sets all markers to zero (off). There are three ways to download waveform files: FTP, programmatically or using one of three available free download utilities created by Agilent Technologies: • N7622A Signal Studio Toolkit 2 • Agilent Waveform Download Assistant for use only with MATLAB • Intuilink for Agilent PSG/ESG Signal Generators NOTE Agilent Intuilink is not available for the Agilent MXG. Agilent N518xA, E8663B, E44x8C, and E82x7D Signal Generators Programming Guide Creating and Downloading Waveform Files Understanding Waveform Data Waveform Data Requirements To be successful in downloading files, you must first create the data in the required format. • Signed 2’s complement •2-byte integer values •Input data range of .32768 to 32767 • Minimum of 60 samples per waveform (60 I and 60 Q data points) • Interleaved I and Q data • Big endian byte order • The same...
