Section II – Installation

Installation Overview

In order to run the PS -Cal software all of the supporting software and hard w a re must first be installed on
the workstation. Along with the PS-Cal software, all of the required software is shipped on the PS-Cal CD.

On the CD you will find the following files and directories: PS-Cal.exe, SetupPS-Cal.msi, setup.exe, PS­CAL-900.pdf (most current revision), licenseAgreement.pdf, changelog.pdf, and R&S Files-.

Installing .Net Framework

PS-Cal requires Microsoft .Net® 4.0 Framework or higher. If necessary, update the workstation .Net
installation at microsoft.com.

Installing Proper VISA Libraries

PS-CAL is designed to work will any VISA library. Use the manufacturer VISA installations for your
hardware requ irements.

Example: If using National Ins truments GPIB-USB-HS you would need the National Instruments VISA
libraries.

Installing PS-CAL

Once .Net Framework and VISA libraries are installed, use the Setup.exe found on the PS-CAL installation
disk to install the PS-Cal software.

First Run

Power sensor calibration templates must be installed before using PS-Cal. When running PS-Cal for the

Section III – Work St a tion Configuration

Measurement Methodology Selection

PS-Cal allows for multiple power sensor calibration methodologies. When using with TEGAM hardw are the
RFBridge_MultiRun methodologies should be used.

Station Configuration

PS-Cal maintains a station configuration file on the local hard drive storing a list of the standards used and
the VISA resource string / GPIB address of the standard.
To open the station configuration file, select Configuration -> Edit Configuration

The Available Drivers list on the left hand side contains a list of all the standard s this version of PS-Cal
supports. The Configured Drivers list on the right lists all the standards configured on this station. This
list contains the name of the driver followed by the instance of the driver. The instance of the driver is
used to distinguish instruments in configuration us ing two or more standards of the same type. For
example, if the station is configured with two TEGAM 1830A’s, the Configured Drivers list would contain
two configuration lines, “TEGAM 1830A” and “TEGAM 1830A”.

Note: Only the standards listed in the Configured Drivers list are available for use in PS-Cal. All

drivers must be configured before they are available in the template configuration wizards.
The Driver Details section of the form shows the configuration details for this instrument. Each driver
must be configured with an Instance and Resource String.
The Instance must contain a number that uniquely identifies the driver / instrument. Typically, the first
instrument used is 1 and any other instruments of the same type are 2, 3, 4, etc.

Section III – Work St a tion Configuration

The Resource String is a standard VISA resource string. The Resource String defines how PS-Cal will
communicate with the instrument. Typically, instrument communication is d one over the GPIB bus, but
PS-Cal is able to communicate with instruments via Ethernet, USB and RS-232. The VISA resource string
is a strictly formatted string. GPIB configured instruments are formatted as follows:

GPIB<Card Number>::<GPIB Address>::INSTR.

Note: Refer to the National Instruments VISA documentation for configuration formats for Ethernet , RS­232 and USB instruments.

The second tab on the Station Configuration form also contains a list of global station variables. PS-Cal
uses the variables as global variables to set values, custom configurations and execution options.

Creating a Calibration Template

PS-Cal is a template-driven calibration package. This allows you to create several calibrat ion
configurations and s ave each configuration as a separate template. To recall a configuration in the future,
simply load the appropriate template.

Blank templates are created in PS-Cal by clicking Tools -> Create Blank Templates. These bl a n k
templates are stored in the “C:\PS-Cal_V4\_Blank Templates\” directory.

Figure 4.1 Creating a Calibration Template

The first step in creating a calibration template is to open a blank template. In the PS-CAL menu, select
File -> Load and navigate to the “C:\PS-Cal_V4\_Blank Templates\” directory. Select the blank
template of the power sensor model you are creating a calibration template for and press Open.
PS-Cal reads the required tests from the blank temple and prompts you for details on the Measurement
Methodology and standards you will use for this calibration. The required test steps for each power sensor
vary based on the manufacturer’s written requirements. PS-Cal prompts you through the calibration steps
including rho, cal factors, linearity, and EEPROM read / write.

Section IV - Operatin g Inst ru ct ions

pressing the Station Configuration button (see section on Station configuration). Once you have
decided on the driver you want to use, select it and press Continue.
After all the Standards have been selected in PS-Cal, you are prompted to set the test parameters for the
test group. These parameters configure the specific options of the test methodology allowing you to fine
tune the specifics of each test methodology. For specifics on each option, see the supporting test
methodology documentation.

Note: Test parameters are editable after the template has been configured. Most test methodologies have

a PARAM button which loads the parameters window.

PS-Cal repeats this process of selecting the Measurement Methodology and Drivers until all Measurement
Methodologies and drivers have been configured.

Loading a Calibration Template

To load a calibration template in the PS-CAL menu, select Calibration Template -> Load and navigate
to the “C:\PS-Cal_V4\Calibration Templates\” directory. Select the calibration template of the power
sensor you are calibrating and then press Open.

Setting Additional Parameters in the Calibration Template

After creating a calibration template, there are some additional parameters and data that may need to be
updated. The parameters set variables defining how PS-Cal performs the calibratio n, and they vary with
each test methodology. Though these variables can be set a nd upda ted a t a ny time, for consistency, we
recommend that you update them when the template is first created, and if they are modified later, that
you save the updates back to the template file.
For each test in the power sensor template there is a parameters button on the screen. The parameters
window is opened by pressing the “Param.” button. Simply update the value in the value column and
press Close.

Section IV - Operatin g Inst ru ct ions

Figure 4.5 Configuring Parameters

In addition to the parameters data, the following values ma y need to be updated before the calibration
template is saved:

1) Uncertainties By default, PS-Cal calculates on the measurement uncertainties and updates the
column if the column contains “- -. “ If you would like PS-Cal to report uncertainties that are on
your scope, you can updat e this column and save the changes back to the template. This will force
PS-Cal to use your uncertainties on all reports.

2) OnLabel For many power sensors that have a calibration label, the calibration template can test
more frequencies than fit on the label. Under the C a l Factor test there is an OnLabel column.
This column controls what frequencies will be printed on the calibration label and the data can be
updated with Yes and No values. PS-Cal ignores this data for power sensors that do not require a
printed Cal Factor label.

Once all the data and parameters are set in the power sensor template, save the template to update it
with the changes. See “Saving a Calibration Template. “

Section IV - Operatin g Inst ru ct ions

Running a Calibration

Once a power sensor template is loaded, PS-Cal displays one tab for each required test step. The exact
steps required for each power sensor and each measurement methodology vary. These tabs are loaded in
order of operation from left to right.

Figure 4.6 Running a Calibration

Two default tabs are loaded with every power sensor. The first is the UUT tab containing information
about the Unit Under Test (UUT, also known as Device Under Tes t, DUT) and the work order. Data such
as the UUT Serial number, Asset number, Job number, and the Calibration Technician (Cal Tech) w ho
performed the calibration must be updated on this tab.

The last tab is the Cal Report tab, which is used to print the report data for the calibration. Onc e all the
steps between the UUT tab and the Cal Report tab have been completed, the data is ready to print.

Figure 4.7 Calibration Default Tabs

4-5

Section IV - Operatin g Inst ru ct ions

Under each test procedure tab, there is a button bar w ith a button for each of the steps required to
complete that calibration step. Like the tabs, the buttons are organized in step order from left to right.
The exact buttons that appear on the form varies with each test methodology.

Figure 4.8 Calibration GUI

These buttons are enabled and disabled as required by the test procedure. A button remains disabled until
necessary prerequisite steps are performed. For example, the Cal button is turned off until the Configure
Station button has been pressed and the configure station operation has been completed. Then PS-Cal
turns on the Cal button and allows you to go to the next step in the calibration process.
Another button to make a special note of is the Halt button. This button is used to halt the application.
For example, if for some reason something was not hooked up correctly or you just need to stop the
program, simply press the Halt button and PS-Cal will stop executing the calibration steps and reset all
the standards to a safe state.

Saving Calibration Data

After you have completed a calibration (or at any point during the calibration), you can save the
calibration data to disk. We recommend you save your calibration data often, to prevent loss of data due
to a power outage or power failure.
To save your cal ibration data

1. Select UUT -> Save As and navigate to the “C:\PS-Cal_V4\CalResults\” directory.

2. Enter the file name of the calibration data you are saving (we recommend you use a standard
naming conventions of either <JobNumber>.xml or <AssetNumber><CalDate>.xml).

3. Press Save.

Uploading Calibration Data

If the sensor has an EEPROM (Electronic, Erasable Programmable Read Only memory), you can upload the
calibration data to the sensor.
To upload the calibration data:

1. Click the Upload Data tab.

2. Click the Download Data button. This brings up the data for viewing. You will also see the word
“Ready!” indicating that the data is now available for upload to the EEPROM on the sensor.

3. Click the Save/Backup Sensor Data to File button. This makes sure that the data is saved, in
case there is a malfunction with the sensor prior to uploading.

4. Select whether to upload the data for

a. Header
b. Cal Factors

PS-CAL in Batch Mode

PS-Cal is able to calibrate power sensors in batch mode. Though PS-Cal can only calibrate a single sensor
at a time, Batch Mode allows the operator to configure that station to test one power sensor, and then use
that configuration to calibration the next sensor in the batch. This process saves time, because many
power sensor calibration configuration steps are time consuming.

Figure 4.11 Batch Mode

To use PS-Cal in Batch Mode:

1. Click on UUT in the menu bar

2. Select New.
This adds an Asset tab.

3. Label the tab by selecting it, and then selecting the UUT tab, and entering the asset number in the
Asset Number field.

4. The new asset tab is now labeled.

You can now select the newly added asset by clicking its tab along the left. Configuration information and
data collected on one power sensor is shared with all the power sensors that are open.
