Introduction

Welcome to the PWRVIEW online help for the Tektronix power analyzers.

PWRVIEW has been designed to make power measurement and a nalysis as simple as possible using Tektronix power analyzers.

Measure efﬁciency, energy consumption, standby power, harmonics, and other power parameters for

single and three phase applications

Remotely monitor, control and log power measurements

Take measurements simultaneously from multiple power analyzers

View voltage, current and power waveforms

Chart har

Set custom measurement limits to monitor when measurements have exceeded a user speciﬁed

thresho

Trend measurements by plotting their values over time

Save measurement snapshots

Record results for future analysis in spread sheets or comma separated value ﬁles

Run, compliance and pre-compliance tests for various regulatory standards such as IEC 62301

(Standby Power), IEC 61000-3-2 (Current Harmonics) or MIL-1399 (Current Harmonics)

monics to instantly visualize a voltage or current frequency spectrum

Minimum system requirements

The minimum system requirements for running PWRVIEW are:

Microsoft Windows 7 or 8.1

2 GHz or faster 32-bit (x86) or 64-bit (x64) processor

2 GB RAM (minimum), 4 GB RAM (recommended)

inimum display resolution of XGA (1024 x 768)

PWRVIEW also supports "Virtual" instruments; these instruments can be used to learn the features of

ither product without a physical instrument being present.

Use the Setup Setup Wizards make the most complex measurement settings simple by taking you step by step through your unique requirements.

Use the Measure all the selected measurement can be viewed in a grid. Harmonics, waveforms, and trend plots can also be enabled on this screen.

Network (see page 17) conﬁgures the IP addresses over which to communicate

PWRVIEW interacts with one or more power analyz ers to send setup information and receive measurement results. Communication is achieved using TekVISA software which is available from www.tek.com VISA system manages all communications links allowing PWRVIEW to use a common framework regardless of the physical communication layer chosen. NI-VISA, National Instruments VISA, is also supported.

Communication is possible u sing USB, Ethernet, and GPIB. All three buses are always available on the PA1000 products. GPIB is optional for PA3000 products.

.The

USB connections

Using the Universal Serial Bus is the simplest way to connect your instrument to the computer. Just plug a cable into any USB port on the computer running PWRVIEW and the square USB port (Standard B) on the rear of the instrument. The computer should automatically detect and install an appropriate communication driver. After driver installation, the attached power analyzer will be shown in the list of available instruments.

Ethernet (Network) connections

Unlike USB and GPIB, an Ethernet enabled instruments are not automatically detected by VISA. The IP address of each instrument must be entered into the Network address dialog box approach eliminates long VISA Ethernet search times.

First connect both the PWRVIEW host computer and power analyzer onto the same Ethernet network. The power analyzer will, by default, obtain an IP address automatically from the DHCP server. The IP address can be accessed on PA1000 front panel by selecting Menu → Interfaces → Ethernet → Current IP Settings. On the PA3000, the IP addresses can be accessed on the instrument front panel by pressing the Setup button and then scrolling to the bottom of the screen.

Once the correct network IP address is entered into the Network dialog box, the instrument will be added to the list of available instruments.

(see page 17).This

GPIB connections (IEEE 488.1)

General Purpose Instrument Bus connections require the addition of a GPIB controller to the host computer. GPIB controllers come in a variety of formats from PCI cards that require installation inside desktop computers to USB-GPIB converters that can simply be attached to the USB port of the computer.

14 PWRVIEW Online Help

Setup Add

Whichever option is used the manufacturer must supply drivers that interface with the VISA system. Connect the instrument to the GPIB controller using a GPIB cable and the instrument should be shown in the list of ava

ilable instruments.

2. Select the instrument to remove.

3. All selected instruments will be removed from the project.

Setup Network

Network

The Network dialog box speciﬁes instrument IP addresses. PWRVIEW will only searc h the Ethernet for addresses in this list.

The Add area allows you to enter new addresses to be searched. To remove an address, select it from the list and click Remove.

The addresses in the list will be searched when the Add instrument function is performed.

The IP address list will be searched each time instruments are added. Therefore this list should be kept as small as possible. Addresses that are not valid extend the search time.

Application Mode

Use the Application Mode to select either the Measure or Test modes. The Applications / Test (see

page 21) area on the left side of the screen provides a list of preset applications and tests. The selections in

the list depend on the instrument; The PA3000 and PA4000 have different tests than the PA1000. The application mode selection helps set up the measurements or tests for your particular application.

Depending on the application mode, some selections are grayed out and are not active until you change the mode. For example Compliance Tests are not available in Measure mode, but only in Test mode.

Use Measure to select the measurements, such as AC Power or LED Driver Input, and then click either the Wizard button or the Apply button. After selecting the measurement, the conﬁguration details appear on the right side of the screen. When you select the Measure applicat available where you can start or stop measurements and display the results using different tools such as
