Preface
Products
The Tektronix PSM3000 Series, PSM4000 Series, and PSM5000 Series RF
and Microwave Power Sensors/Meters convert radio frequency (RF) and
microwave power into digital data at the point of measurement. They are ideal
for troubleshooting and characterization in the lab, and can be used for radio
frequency (RF) component testing. These products connect directly to a desktop
or laptop computer with a USB 2.0 port and cable.

Preface
viii RF and Microwave Power Sensors/Meters

Getting Started
This section provides the following information:
How to install the software
How to install the USB driver and connect to a computer
How to start and application and perform a functional check
Install the Software
Before connecting the instrument to a computer, you need to first load
the software provided on the USB memory device that shipped with your
instrument. You can also find the latest software on the Tektronix Web site at
www.tektronix.com/software.
Computer, System, and
USB Requirements
Computer hardware requirements. The computer onto which you are downloading
the instrument software must have at least 2 GB RAM and a USB 2.0 port that
supplies more than 450 mA at 5 V.
Power requirements. This instrument is powered through the USB cable when
connected to a computer. The USB 2.0 port of the computer must supply more
than 450 mA at 5 V. Tektronix recommends using the USB cable supplied with
this product. The supplied cable has 20 AWG power conductors that are a heavier
gauge than most USB cables.
NOTE. Refer to the Specifications section of the PSM3000, PSM4000, and
PSM5000 Series RF and Microwave Power Sensors/Meters Specifications and
Field Verification Technical Reference for additional information on electrical
requirements.
Hub recommendations. A USB host port on a computer will provide adequate
power for the instrument under normal circumstances. However, if you use a
USB cable longer than 3 to 5 meters, are connecting multiple instruments, or
are using a portable computer that runs on battery power, you will need to use
an active or self-powered hub.
The instrument typically draws 450 mA at a nominal 5 VDC. An active hub
compensates for the DC voltage drop in a USB cable longer than 3 to 5 meters.
It also conserves battery life in a portable computer.
System Requirements. The instrument software you are downloading is
compatible with the following operating systems:
RF and Microwave Power Sensors/Meters 1

Getting Started
Windows XP, Service Pack 3
Windows Vista
Windows 7 (32 or 64-bit, or XP mode)
Software Installation
Procedure
This procedure allows you to install one or more of the following software
applications or programs:
Power Meter application: provides a virtual power meter front panel for your
instrument. Use the application software to make power meter measurements.
High-speed Logging application: allows you to take raw, high-speed
readings from your instrument.
Pulse Profiling application: (PSM5000 series only) provides the tools for
complete characterization of a modulated signal.
Sample Code: provides programming examples for remote control of
the instrument. You can read more about remote programming in the
PSM3000, PSM4000, and PSM5000 Series RF and Microwave Power
Sensors/Meters Programming Manual available on the Tektronix Web site at
www.tektronix.com/manuals.
