FAQ 2017-05-24

N9080B SEM measurement defaults seem to be different from 3GPP 36.141 V12.12.0 (2016-06). Is N9080B doing something it shouldn’t?
To make a “True RMS detection”, as requested by the 3GPP conformance testing, based on ITU-R SM.329, for a mix of noise-like & CW-like signals under test, use “Peak Detector with very narrow VBW”. Click on the question for additional information.

FAQ 2017-05-24

Is it possible to add the N9080B-2TP with the N9080B-1FP installed on the X-Series Analyzer? Should the N9080B-2FP be used instead?
Yes, this is possible. A combination of fixed and transportable licenses can be used.

FAQ 2017-05-23

Is there a PDF version available of the user guide for the M9210A? There are issues with the .chm file that is available.
No, there is not a PDF version available for the M9210A user manual. To read the .chm file, it must be downloaded and copied on the local C drive before opening.

FAQ 2017-05-23

Does M9393A work without M9300? If so, when using the M9393A with 100MHz reference on a pulse generator, what is the external reference input voltage?
When replacing the M9300 with a pulse generator, self-test and alignments may pass. Click on the question for additional information.

FAQ 2017-05-23

What is the dimension and connector location of each modules of the M9485A?

FAQ 2017-05-09

Is there a 3D model of the InfiniiVision 4000 X-Series oscilloscopes?
Yes, see the IGES, SAP, Step, PKG, X_T, EASM, and PDF format file downloads.

FAQ 2017-05-05

Why is sensor with internal calibration capability not measuring 0dBm after performing zero & calibration process?
Power sensors with internal calibration capability( eg. N192XA, U848x, U2020XA, U2040XA) use its built in reference when performing a zero and calibration.

FAQ 2017-05-05

What is Keysight's Windows 7 to Windows 10 Migration Schedule?
We are beginning the transition of our Windows based instruments from Windows Embedded Standard 7 to Windows 10 IoT Enterprise. Click on the link for additional information.

FAQ 2017-05-04

If we use external clocks for both the Pattern Generator and Error Detector parts, can we run them at different data rates?
It would be more straight-forward to provide the PG (TX) with a 10 GHz clock (for 10 Gb/s data) and then use the 1:4 demux and provide the ED (RX) with a 2.5 GHz clock (measuring 2.5 Gb/s data). Click on the question for additional information.

FAQ 2017-05-03

What is the raw jitter tolerance for the N4960A/N4952A?
There is no CDR in the N4960A, so by itself, the JTOL plot will be a flat line somewhere below 1 UI. An external CDR can be used. Click on the question for additional information.

FAQ 2017-05-03

What is the time out limit of response time (2.4) in M8020A Interactive link training?
The LTSSM (Link Training and Status State Machine) implements the timeouts as specified in the PCIe specification. Click on the question for additional information.

FAQ 2017-04-21

How to perform cal factor correction when using 8480 series power sensor ( with cal factor below 85% or above 100%) with old power meters (HP435B/HP43
If you are using an HP435B or HP436A, the minimum cal factor setting is 85% and the maximum is 100%.

FAQ 2017-03-30

Why is the accuracy of U200x Power Sensors not tested per sensor’s dynamic range?
The accuracy of those sensors is essentially a combination of linearity, instrumentation accuracy and traceability to absolute accuracy at 50MHz, 0dBm.

FAQ 2017-03-29

Why is the linearity of E441x, E930x and E932x Power Sensors not tested per sensor’s dynamic range?
In actuality, there is little necessity to test linearity of the E4412A and E4413A Power Sensors below -20dBm….

FAQ 2017-03-29

What is the difference between the Integrated true-mode stimulus application (opt 460) and the Differential and I/Q devices application (opt 089)?
The Integrated TMSA and the DIQ both simplify measurements of differential (balanced) devices. The two applications however, are used for different measurements. Click on the question for additional information.

FAQ 2017-03-28

When using the DIQ application, what happens when I set the internal receiver to measure beyond the frequency range of my instrument?
Data for frequencies beyond the instrument hardware limitations is extrapolated from the hardware’s maximum and minimum limits. Click on the question for additional information.

FAQ 2017-03-28

How to maintain 16195B?
The 16195B which consists of Open, Short, 50 Ω Load and Low-loss Capacitor terminations is calibration kit for LCR Meter/Impedance Analyzer and Network Analyzer (NA). The 16195B itself does not have warranted specification as independent product. Maintenance of the 16195B depends on what instrument you calibrate with 16195B.
