Getting Started with Remote Operation Interfaces Figure 1-1 Software/Hardware Layers Interfaces GPIB GPIB is used extensively when a dedicated computer is available for remote control of each instrument or system. Data transfer is fast because GPIB handles information in bytes with data transfer rates of up to 8 MBps. GPIB is physically restricted by the location and distance between the instrument/system and the computer;...
Page 14 Getting Started with Remote Operation Interfaces Data transfer using the LAN is fast as the LAN handles packets of data. The single cable distance between a computer and the signal generator is limited to 100 meters (100Base- T and 10Base- T). The Agilent MXG is capable of 100Base- T LAN communication.

This is commonly referred to as byte swapping. You can swap bytes either programmatically or by using either the Agilent Technologies Intuilink for ESG/PSG Signal Generator software, or the Signal Studio Toolkit 2 software. For the signal generator, byte swapping is the method to change the byte order of little endian to big endian.

Creating and Downloading Waveform Files Waveform Phase Continuity Sampled Sinewave with Phase Discontinuity Phase discontinuity Waveform length Avoiding Phase Discontinuities You can easily avoid phase discontinuities for periodic waveforms by simulating an integer number of cycles when you create your waveform segment. NOTE If there are N samples in a complete cycle, only the first N- 1 samples are stored in the waveform segment.

The generated 3- tone test signal requires 100 samples in the waveform to maintain periodicity for all three tones.

When you create your user file data, it is important that you organize the data in this manner. Within groups (strings) of bits, a bit’s value (significance) is determined by its location in the string.

Creating and Downloading User-Data Files User File Data (Bit/Binary) Downloads (E4438C and E8267D) Binary File Type Data With the Binary file type, the signal generator sees all of the bytes within the downloaded file and attempts to use all of the data bits. When using this file type, the biggest challenge is creating the data, so that the signal generator uses all of the bits (bytes) contained within the file.
