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 d irectly to a desktop
or laptop computer with a USB 2.0 port and cable.

Getting Started
Install the Software
This section provides the following information:
How to install the software
How to install the U SB driver and connect to a computer
How to start and application and perform a functional check
Before connecting the instrument to a computer, you need to rst load the software provided on the USB memory device that shipped with your instrument. You can also nd the latest software on the Tektronix Web site at www.tektronix.com/software.
Computer, System, and
USB Requirements
Compute
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 this product. The supplied cable has 20 AWG power conductors that are a heavier gauge than most USB cables.
NOTE. Refer to the Specications section of the PSM3000, PSM4000, and
PSM5000 Series RF and Microwave Power Sensors/Meters Specications and Field Verication Technical Reference for additional information on electrical
quirements.
re
Hub recommendations. A USB host port on a computer will provide adequate power for the instrument under normal circumstances. However, if you use a
SB cable longer than 3 to 5 meters, are connecting multiple instruments, or
U 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.
