test times and provide dynamic power measurement information that
was previously unavailable. An included High-speed Logging Application
provides a mechanism for getting this data into your PC for analysis.
For custom test applications, you can communicate with the sensors
using LabVIEW, or using a fully documented API. Example programs are
provided for the most commonly used development environments. The
communications library allows your program to communicate with up to
12 sensors, eliminating the need for costly switches.
Tektronix real-time signal analyzers, arbitrary waveform generators, and
oscilloscopes that use the Windows operating system can also be used to
control the PSM Series sensor/meter and give you quick access to accurate
power measurements.
To allow synchronization with other measurement equipment all models
include Trigger In and Trigger Out TTL signals.
High-speed measurements, extensive programming tools, and
synchronization features make these sensors versatile additions to your
test setup.

Capable, Compact Power Sensors/Meters
The PSM3000, PSM4000, and PSM5000 Series are compact power
sensors/meters that deliver fast, accurate RF and microwave power
measurements. A broad range of CW and pulse modulation measurements
are available, depending on the series you choose. Each meter comes
with Windows Power Meter application software for controlling the
meter, displaying readings, and recording data. The combination of the
sensor/meter and PC provides a complete solution, eliminating the need for
a separate, dedicated meter mainframe.
No Meter Mainframe Required
With the included power meter application software, familiar meter controls
are available at the click of a mouse and readings are presented right on
your PC screen. Familiar Windows pull-down menus provide additional
controls. Data is immediately available on the PC for further analysis and
documentation. The meters communicate with the PC using standard
USB 2.0 protocols and cables for plug-and-play ease of use.
Industry-leading Performance for Demanding
Designs
Tektronix power sensors/meters come fully calibrated over their entire
operating temperature range. Sensor zeroing and meter reference
calibration have been eliminated, reducing setup time and helping to
avoid inaccurate results. These meters provide accuracy you can count
on for general-purpose CW, peak, pulse, and other modulated power
measurements. Whether doing installation or maintenance on a wireless
base station, production testing, or R&D for wireless components, the PSM
Series products serve these needs with a wide dynamic range (–60 dBM to
+20 dBm) and frequencies ranging from 10 MHz up to 26.5 GHz.
Integrate High-speed Power Measurements Into Your
Testing
Tektronix PSM Series power sensors feature the industry’s fastest
measurement speed (2000 readings/s). This can significantly reduce

PSM3000 Series power sensors/meters provide true average power
measurements, giving accurate power measurements independent of signal
modulation and bandwidth. The PSM4000 Series delivers average power
(CW) measurements, and adds pulse and peak power measurements for
gathering basic data on pulsed RF and microwave signals. PSM5000
Series power sensors/meters provide the same measurements as the
PSM4000, and add pulse profiling capability for signal viewing and
characterization in pulsed RF and microwave systems.

A Broad Range of Pulse Envelope
Measurements
Tektronix PSM5000 Series products feature an easy-to-use, high
performance, pulse profiling, pulse (modulation), and CW power meter and
sensor in one. The PSM5000 Series product is specifically designed for
applications requiring time domain analysis of constant-envelope, repetitive
pulsed signals. It performs time domain pulse measurements such as
rise/fall time, overshoot, and droop that have typically required costly signal
analyzers. PSM5000 Series sensors use an equivalent time-sampling
technique to reconstruct repetitive, pulsed input signals. Repetitive pulses
with video bandwidths up to 10 MHz can be measured with an effective
sample rate of up to 48 MS/s.
Performance You Can Count On
In addition to industry-leading service and support, every PSM Series power
sensor/meter comes backed with a three-year standard warranty.
