Waveform Download Problems

Cannot download waveforms to the signal generator

  1. Verify the N7622C Signal Studio Toolkit 2022software is installed.

  2. Verify that the PC can communicate with the equipment.

  3. Remove excess files from volatile memory on your signal generator.

Download Takes a Long Time

If the signal generator connects directly to the PC using a crossover LAN cable and downloading a waveform takes a long time, or there are connection problems even if the ping command is successful, add the signal generator's IP address and hostname to the Hosts file.

The Hosts file is a common way to map a hostname to an IP address. (For more information on Hosts files, go to www.microsoft.com and search on "example hosts file.")

Depending on the operating system, you will find the Hosts file in one of the following directory paths:

C:\Winnt\System32\Drivers\Etc\

C:\Windows\System32\Drivers\Etc\

Procedure

  1. In a text editor, such as Notepad, open the Hosts file. (Drag and drop the file directly into Notepad).

  2. Write the IP address and hostname for the signal generator, and any other instruments used in the system (such as a spectrum analyzer), at the end of the file. See the example Hosts file below.

    Do not use "Save As" when saving the Hosts file; this file does not have a file extension.

  3. Save the file and close the text editor.

Example Hosts File

# Copyright (c) 1993-1999 MicrosoftCorp.

#

# This is a sample HOSTS file used by MicrosoftTCP/IP for Windows

#

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one

# space.

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a '#' symbol.

#

# For example:

#

# 102.54.94.97 rhino.acme.com # source server                  

# 38.25.63.10 x.acme.com # x client host                       

127.0.0.xxx localhost          

141.xxx.60.xxx signal generator hostname        

141.xxx.40.xxx spectrum analyzer hostname
