If the ESG is connected directly to a computer, use a crossover LAN cable; if the ESG is connected to a network/hub/router, do not use a cross-over LAN cable.
Cannot establish communication between the PC and the signal generator. The signal generator does not respond to the software.
Ensure that the cable and all connectors are undamaged.
Ensure that the GPIB cable is securely connected to the PC and the signal generator.
Use the System Configuration Wizard to set the mode to RF Playback, set the connection type to GPIB, verify the GPIB address, and test the I/O connection.
In the Signal Studio Software Installation Guide, review the GPIB setup sections, and the information about installing Agilent I/O libraries.
If you are using a National Instruments (NI) GPIB card and errors occur when you download a waveform, follow steps 1-3 below. If you have both an Agilent and a National Instruments GPIB card installed, and you want to use the Agilent card, you will also need to perform steps 4-5.
Uninstall any Agilent IO Libraries that you have previously installed.
Ensure that you have both the NI PCI card drivers and NI VISA installed, and verify that the NI card is working.
Reinstall Agilent IO Libraries version 14.2. If you select a ”Custom” installation, make sure the ”Agilent VISA as primary VISA” is unchecked in the Select Features window. This is the default setting for a ”Typical” installation.
Continue with steps 4-5 only if you have both Agilent and NI GPIB cards installed.
Open National Instrument's Measurement and Automation Explorer (MAX).
Select Tools > NI-Visa > Visa Options > Passports. Ensure the NiVisaTulip.dll box is checked.

Ensure that the cable and all connectors are undamaged.
Ensure that the LAN cable is securely connected to the PC and the signal generator.
Ensure that the instrument LAN connectors are active: flashing green or yellow lights indicate LAN activity.
Use the System Configuration Wizard to set the mode to RF Playback, set the connection type to LAN, verify the hostname or IP address, and test the I/O connection.
Run the 'ping' program:
On the computer go to Start > Programs > Command Prompt (or DOS).
At the C:\>
prompt, enter ping
<IP address>,
where <IP address> is
the signal generator's IP address.
If the signal generator does not respond, contact your IT department for help.
If the 'ping' program works correctly, but there is still a connection problem, AND the PC is connected directly to the ESG (using a cross-over cable), add the ESG's IP address and hostname to the Hosts file, at:
C:\Winnt\system32\drivers\etc\Hosts
In a text editor such as Notepad, open the Hosts file.
Write
the IP address for the signal generator and spectrum analyzer at the bottom
of the file.
(Refer to the example of a hosts file below)
Save the file to C:\WINNT\System32\drivers\etc, and close the text editor.
