3Capability

This software provides for automating measurements of the test com­ponents contained in a WILTRON 3666, 3667, 3668, 3669, or 3669B
Verification Kit.

It compares the measurements made on your 360X/372XXA with the
test component data provided in each verification kit. This will aid in
determining if the measurement values obtained for the components
are within the uncertainty limits provided on the data disk packaged
with each verification kit.

4 Dat a Ou tpu t

The test data and results are output in the form of fou r files to th e root
directory of your computer’s drive C:\ (in the root directory.) The
default file names are:

Page 1

20db_pad.dat
40db_pad.dat (or 50db_pad.dat)
air_line.dat
rho__std.dat

NOTE:

The Performanc e Verification Softwar e allow s you to ren ame
these files to file names of your choice with default “.dat”
extension.

The tabular data in each file is given at discrete frequencies (1.0, 1.5,
or 3.0 GHz inter vals—de pendin g on the con nector type and co rrespond ­ing frequency range).

The program now prompts you to verify that the Verification Kit data

disk is installed in drive A: of your computer. Install the disk if you
have not already done so.

18 Measuring the Verification Devices

The program now presents the follow ing menu on the computer scree n:

(1) Measure 20 dB Attenuator
(2) Measure 40 or 50 dB Attenuator
(3) Measure Beatty Standard
(4) Measure Airline
(5) Exit

Enter the number corresponding to the action you wish to take.
At this point you can begin measuring your verification kit devices. As

you select a verification device, the program prompts you to enter the
serial number of the device and to orient the device with the label
facing the user. Such orientation places port 1 on your left. It is at this
measurement point that the device is installed and measured on the
VNA. See Figure below showing the measurement setup.

The computer will now read data from the Verification Kit data disk
(installed in drive A:.) The verification software then automatically
measures the device with the VNA and compares the measured data
with the data stored on the Verification Kit data disk. The results and
measurement data is stored to data files on your C: hard drive (see
Section 1-4, Data Output for file names.) The data on each file will

contain an asterisk (*) next to measrement data that is not within the
specified limits.

The above steps can be repeated for each of the three remaining devic es
in the verification kit: the 40/50 dB attenuator, the Beatty standard,
and the air line.

NOTE:

The software will wr ite the d ata to the file name you choose,
or the default file names in Sec tio n 1-4. If these files alr eady
exist, they will be overwritten. Rename the files if you do

not wish them overwritten with the new data.
To e xit the program, enter 5 at the main menu.
To view or print the data files, simply use any text editor. You can also

view the data files using the batch file called veridata.bat included on
your Performance Verification Software distribution disk.
