Which Application Notes are Most Relevant to the PSA Series Spectrum Analyzer?
This page contains links to application notes that are relevant to PSA Series spectrum analyzers.

FAQ 2012-05-11

How do I correct for external harmonic mixer conversion loss with a PSA Series Spectrum Analyzer (E4440A, E4446A, E4448A)?
The PSA series provides the ability to compensate for conversion loss. You can use one of four amplitude correction factor registers. The correction factors are entered using amplitude/frequency pairs.

FAQ 2012-02-28

How do I remove signal images from the display of the PSA Series Spectrum Analyzer (E4440A, E4446A, E4448A)?
The PSA uses a signal identification process called image suppression. This process removes the images from the display leaving only true signal.

FAQ 2012-02-27

What is the frequency range of the N5532A Sensor Module?
100 kHz to 4.2 GHz, 10 MHz to 18 GHz, 30 MHz to 26.5 GHz, and 30 MHz to 50 GHz.

FAQ 2012-02-26

Why do spurious signals appear in my spectrum analyzer span when I apply a clean signal to the RF input?
Overdriving the input mixer of the analyzer may cause the spurs.

FAQ 2012-02-26

What do the terms "time gating", "gated video", "gated FFT" and "gated sweep" mean in the PSA Series Spectrum Analyzer?
Time Gating is a tool used in Spectrum Analysis to eliminate the transient effects of a pulsed RF signal when the user wishes to observe the signal itself. There are three basic types of Time Gating. Click here for additional information.
