Install the 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 Speci fi cations section of the PSM3000, PSM4000, and
PSM5000 Series RF and Microwave Power Sensors/Meters Speci fi cations and
Field Veri fi cation 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:
