FAQ 2017-02-02

Why is Option DP2 or B40 recommended on the spectrum analyzer (EXA, MXA, PXA) with the EMI Measurement Application(N6141A)?
Time Domain Scan (TDS), Monitor Spectrum, and Amplitude Probability Distribution (APD) all require 2 GB of Capture memory (option DP2). Option B40 includes DP2, so having either option B40 or DP2 will work equally as well for N6141A.

FAQ 2016-10-07

For my UXA Signal Analyzer, what applications support option H1G (1 GHz Analysis Bandwidth) and what additional functionality does it provide?
Option H1G also includes the B2X digitizer. Therefore, option H1G is supported by all applications that support B2X up to at least 255 MHz bandwidth. Option H1G additionally provides 1 GHz analysis bandwidth for some other measurement applications.

FAQ 2016-10-07

What termination model (Balanced vs. Unbalanced) should I use for my M8000 BERT?
For M8000 (M8041A/51A/61A/62A) BERT data outputs, a Termination Model must be selected in the Amplifier section of the Parameters window, Balanced or Unbalanced.

FAQ 2016-07-08

Can I use the Fixture Simulator functions with the 2-port ENA?
Yes, but the function is limited...

FAQ 2015-01-09

When automating markers on the ENA is it possible to programmatically query the indicated inductance or capacitance on a Smith Chart?
The inductance / capacitance information cannot be directly queried via the automation interfaces. The inductance (positive reactance, top half of the Smith Chart) or capacitance (negative reactance, lower half of the Smith Chart) is not available as an automation query.

FAQ 2014-08-11

Is there a summary of available cable test methods when using the FieldFox Hand Held portable analyzers?
Yes. Please refer to the FieldFox Hand Held Cable Test details and methods below.

FAQ 2014-08-11

Why does my FieldFox spectrum analyzer preamplifier increase the noise floor when engaged?
The FieldFox spectrum analyzer preamplifier selection will normally reduce the displayed noise floor when activated. However, if the FieldFox RF attenuation AUTO selection is set to ON then the preamp may not reduce the noise floor.

FAQ 2013-11-17

Can I do voltage measurement using the U2802A rather than temperature measurement?
Yes, you can do voltage measurement easily by using the Keysight Measurement Manager (AMM)...

FAQ 2013-11-17

I am looking at a 160 MHz OFDM signal at 5 GHz on my MXA or PXA signal analyzer. Why can’t I see the whole signal?
The instrument preselector is limiting the bandwidth of the MXA or PXA input.

FAQ 2013-08-07

On the PNA Vector Network Analyzer Family Is it possible to save a Touchstone (SnP) file with unwrapped phase?
Yes. The PNA Family of Vector Network Analyzers can save Touchstone (SnP) files with the phase information as unwrapped phase. To achieve unwrapped phase in a Touchstone file save perform the following...

FAQ 2013-07-29

Where can I find information or example programs using the API for Signal Studio?
The Signal Studio for pulse building help file has information and example programs under the API control chapter.

FAQ 2013-05-16

Does the ENA 6 series have the swept sweep mode in the frequency sweep?
No. The E5061A/62A and E5061B have only stepped sweep mode in the frequency sweep.

Vector Network Analyzer Uncertainty Calculator, What is the Accuracy of My Measurements?
No matter whether you are an experienced or novice user of vector automatic network analyzers, you may have asked "How accurate are these measurements?"

FAQ 2013-01-13

What is the best configuration for wideband I/Q modulation?
An E8267D Option 016 or an N8212A Option 016 signal generator with an M8190A arbitrary waveform generator

FAQ 2012-12-28

Are there any step-by-step measurement examples for ENA 7 series?
Yes. There are some measurement examples in ENA help file...

FAQ 2012-12-28

How many measurements do I need to make and how long is the predistortion data good?
The number of measurements needed depends on the number of parameters that are changed. The calibration (measurement data) could be valid for two days or longer.

FAQ 2012-12-28

Do corrections work with frequency and amplitude offsets?
Yes, however, the amplitude flatness accuracy is set by the spectrum analyzer flatness accuracy across the signal bandwidth...

FAQ 2012-12-28

How much time/frequency error is introduced by the Custom Profile or Custom I/Q resampling?
After using the formula to calculate the number of resampled data points, work backwards to determine the error.

FAQ 2012-12-28

What happens to nested patterns and off-time packets in pulse mode?
Nested patterns are flattened. This means that a single trigger will not play the entire pattern. It merely steps into the pattern and plays the first pulse. The next trigger plays the next pulse, etc. Off-time packets are ignored in pulse mode.

FAQ 2012-12-28

Why can’t I view a help file downloaded from the Keysight website?
After downloading the file to your PC, open it from the location it was saved and a security warning appears. To view the help system, clear the checkmark from the "Always ask before opening this file" check box.
