-
-
- NOTE: Trouble shooting information is at the end of this file.
-
-
- Installing:
- ~~~~~~~~~~~~
- Due to many versions of "Windows (tm)" out in the world at the
- present, and the difficulty I had trying to get Visual Basic's(tm)
- install program to work across all platforms. I decided to go
- to a manual install procedure. Please forgive me! {:-(
-
- Zip File Instructions: If you recieved the files as a file
- called analyzer.zip, copy the file to a floppy disk then
- unzip it using the command line "pkunzip -d analyzer".
- Note: The '-d' is very important to keep the directories straight.
-
- This will extract the proper files in the proper directories.
- Then follow the procedure below. This assumes that you have
- PKUNZIP on your system path somewhere. If you do not have
- PKUNZIP, see the ARRL BBS or web site at www.arrl.org.
-
-
- Backup Procedure:
- ~~~~~~~~~~~~~~~~~
-
- Note: Generally this series of steps should never be required
- but just to be extra safe, you may wish to back up the
- following list of files from the c:\windows\system directory
- before proceeding with the install. By backing up these files
- you are assured that if anything goes wrong after the Analyzer
- install, that you can safely recover.
-
- The files that Analyzer needs to put in the C:\Windows\System
- directory are:
-
- ANIBUTON.VBX
- LEDDISP.VBX
- MSCOMM.VBX
- MSMASKED.VBX
- SPIN.VBX
- THREED.VBX
- VBINI.VBX
- VBRUN300.DLL (This file may not be visable on WIN95
- Select View->Options->View and make all files Visable to see it)
-
- If your system does not contain one or more of these files
- before the install, don't worry. Just back up the ones that
- you have to a floppy.
-
-
- Install Procedure:
- ~~~~~~~~~~~~~~~~~~
- Note: If you get an overwrite warning message during any of
- the copy commands that you are about to do, please ONLY
- OVERWRITE files where the "Replace With" file from the
- floppy is newer than the file on your hard disk.
-
- Note: Under NT4.0 or Win95 set the options -> view menu to
- "Show All Files", you can restore the setting after you are
- done installing the program. Otherwise you may not copy the
- file a:\system\vbrun300.dll to c:\windows\system.
-
-
- 1) Make a directory on your hard disk called Analyzer. This is
- where the program will be installed.
-
- 2) Open the Analyzer folder on the install floppy and copy
- the contents to the analyzer directory you just created.
-
- 3) Open the windows folder on the install floppy and copy those files to
- the proper windows folder on your hard disk.
-
- 4) open the system folder on the floppy and copy those files
- to your Windows/System directory on your hard disk.
-
- 5) You may wish to make a folder or program group with the
- Analyzer.exe file to make running the program easier in the
- future.
-
-
- Running The Set_Port Utility
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- A utility has been included to help you configure the Network Analyzer
- on your computer. Attach the analyzer to the RS232 port that you wish to
- use. Make sure that the Network Analyzer is ON. Run Set_Port from the
- copy on your hard drive (c:\Analyzer directory). The first step this
- program does is find all valid RS232 ports that it can. A list is
- displayed, and you are given an option of trying to setup the Network
- Analyzer automatically or quitting. Select Setup, the program then tries
- to open all the valid ports it found in the first step and locate the
- Analyzer by writing commands to it and looking for the proper response.
- If the Analyzer is found, the program then tries to open the file
- Analyzer.ini, this file must be located in your Windows directory (see
- install instructions above). If the Analyzer.ini file is opened properly
- the line "Com_port =" is set to the port the network analyzer was just
- found on.
-
- If all was sucessful (read the messages provided by Set_Port) the Analyzer
- is now properly configured to run.
-
- Note: Since this program opens RS232 Ports and writes information to them, there
- is a slight chance that another device connected to a port may be initilized
- improperly and may not function as intended later. Any problems may be fixed by
- restarting your computer. Any problems caused by the Set_Port problem will
- not happen with the Analyzer program, as program only looks at the Com port
- it was configured for (from the file \Windows\Analyzer.ini).
-
-
- Manually Setting The Network Analyzer Port
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Note: This is how to edit the Analyzer.ini file manually, use the procedure
- above (set_port) unless there is some real need to manually edit the ini file.
-
- The default COM port is COM 1, if your hardware is not connected to COM 1
- then you may edit the Analyzer.ini file manually to set the proper COM
- port. Run the notepad, open the Analyzer.ini file in the windows
- directory and look for the Com_Port = line, then set the number after
- the equals sign to the proper COM port for your computer. Save the file
- and exit notepad. After this is done, restart Analyzer.exe and try to do a
- sweep again.
-
-
- Running Analyzer.exe
- ~~~~~~~~~~~~~~~~~~~~
- Run Analyzer.exe, the initial screen shows a black background with the
- build information displayed.
-
- No graph is displayed until a sweep is done.
-
- The various menu commands are described below,
-
-
- Main Form Menu Commands
- =======================
- File - This menu allows you to,
-
- Print - Print the current graph screen
-
- Exit - Exit the Analyzer program
-
- Sweep - Select this item to start a frequency sweep
- (More about sweeps below)
-
- Manual Mode - This brings up an interactive screen for single
- frequency operation of the Network analyzer.
-
- Cursor - After a sweep is done this command enables and places
- cursors on the screen. The red cursor is moved by pressing
- the left and right arrow keys (Actually pressing AND releasing
- the key moves the selected cursor).
- The green cursor is moved by holding the shift key and pressing
- the left or right arrow keys.
- The cursor information is displayed in a window at the lower
- right corner of the screen. This screen may be moved by dragging it
- to a different location.
-
- The cursor window displays the frequency and amplitude data for the
- red (R), green (G) and delta between red and green (D) cursors.
- Turn cursors off by selecting the cursor command again.
-
- View - After a sweep is done this command enables and allows the following
- things to be done,
-
- Area - Zooms to a area of the graph, Select this command, position
- the mouse at the upper leftcorner of the area to be viewed.
- hold down the left mouse button and drag the mouse to the
- lower right of the area to be viewed. When the bounding box
- covers the proper area, release the mouse button. The display
- now will zoom into the selected area.
-
- Fit - This undoes a 'view area' and fits all the data to the whole
- screen again.
-
- Refresh - This redraws the current screen. Useful if some other
- program trashes the display memory.
-
- About - This displays an about box for the Analyzer program.
-
-
- Sweep Mode
- ==========
- When this menu item is selected, another window pops up for setting the
- sweep parameters.
-
- Set the desired start and stop frequencies and number of points to for the
- sweep.
-
- Pushing the "Setup" button will bring up a setup screen that allows the
- probe attenuation factors to be set. This screen also allows the maximum and
- minimum source to be set for the sweep. Press "OK" when done here.
-
- Back at the "Sweep Setup" screen press "Start Sweep" button when the
- sweep parameters have been set.
-
- The sweep now starts, the black LCD window displays the sweep progress.
-
- At any time during the sweep, the "Stop Sweep" button may be pressed to
- stop the sweep (This is useful if you notice bad data during a long sweep). To
- restart the sweep select the sweep menu item again.
-
- When the sweep ends the setup screen closes automatically and a graph of the
- data is displayed. The View and Cursor menu items are now active.
-
-
- Manual Mode
- ===========
- Picking the manual menu item allows complete manual control of the hardware.
- A single frequency may be set by clicking on the spin buttons. When the
- frequency is changed, the frequency display turns red. A red indication shows
- that the
- hardware has not been updated to the new frequency yet. To update the
- hardware, press the Set rocker switch. Doing so will send the proper code to
- the hardware, setting the frequency. The display will turn black again to
- signify that the frequency is current.
-
- The source amplitude may be set at any time. The source attenuator is updated
- as soon as an option button is selected.
-
- The receiver settings may be altered for X1 or X10 probes and auto scaling
- or manual setting of the receiver attenuators. By turing off the Autoscale On
- check box the receiver attenuators will be settable by you. You may set the
- attenuators on or off as desired. Setting Autoscale ON will re-enable automatic
- selection of the receiver attenuators.
-
- Leaving the autoscale on is the recommended setting. Use the manual settings
- for calibration or troubleshooting.
-
- The output window is updated every second as the A/D's are read. The results
- are displayed for each channel and the dB ratio of both channels is also shown.
-
-
- Troubleshooting
- ===============
-
- If windows is not in the directory C:\Windows, you may need to copy the
- file "Analyzer.ini" manually. This is done by copying "Analyzer.ini" file from
- the floppy disk to the directory where windows is installed on your computer.
-
- The program may appear to hang for up to 30 seconds or so when the Sweep or
- Manual
- menu items are selected and the hardware is not responding. Wait for the error
- message. Then determine the cause of the error,
-
- * The hardware is not plugged into the computers COM port or is not turned
- ON.
-
- * FYI: If the network analyzer is talking to the PC the red "Data" LED will
- be blinking as measurement results are sent back to the PC.
-
- * If you get an error that the Analyzer.ini file is missing or corrupt,
- copy the file from the master disk to the windows directory, and run the
- Set_Port program again (with the analyzer connected and ON).
- This should solve the error.
-
- * If you can't resolve the problem, end the program.
- Unplug the Analyzer from the RS232 port and turn it off
- for 15 seconds. Then turn the analyzer ON and reconnect it to the RS232 port.
- Try and run the Set_Port program again to be sure that the network analyzer
- is running properly. If the problem persists, restart your computer and reset
- the analyzer by unplugging it and cycling power as above.
-
- * If you continually get errors, you may need to change the RS232 delay. This
- parameter is in the Analyzer.ini file. Increasing the delay tells the program
- to wait for more time before trying to read the data back from the RS232 port.
- You may need to set this parameter on very slow computers, i.e. < 486 DX models.
- Also computers that use 8250 UART's may need the delay adjusted. If you have
- no RS232 problems leave the delay at 0 for maximum performance.
- Don't go overboard with this number, as it will slow down the operation of the
- program during sweeps. You won't notice any delay during manual operation. On
- Pentium computers this parameter has not been needed, so look for the error
- elsewhere (i.e. like the RS232 wiring). Start by setting the delay to 1, this
- enables the delay function and allows the computer time to service the RS232 port.
- Increase RS232 delay in 1 mS increments (steps of 1), until the problem goes away.
- Note: Always lok for all other problems first, no computers to date have needed
- any more delay that 1mS.
-
- * I have noticed a few SVGA modes on some display boards that fail to display the
- grid completely (i.e. the graph border is not present). If this happens switch to
- 640x480 mode. Also printing may be better with 640x480 mode. Different resolutions
- may crop the graph when printed depending on the printer/display resolution
- selected.
-
- * Printing: Printing is done by doing a screen dump to the printer. In higher
- resolution modes the graph may be chopped off. This is caused by more Pixels
- being on the screen, and the printer driver cutting some off. A general cure
- is to run in 640x480 mode. I have not found a printer that would not work in
- this mode (yet!). Likewise, if the printer plot is too small, you might try
- to run at higher than 640x480 resolution to put more pixels on the screen.
