What is the internal Arb trigger delay jitter?
The internal Arb trigger delay is generated using a free running oscillator.

FAQ 2012-12-28

How do I switch between trigger modes?
Any change between None, Continuous, or Single trigger mode requires only a "play" to update the Arb. Any change to or from the pulse trigger mode requires a "download and play". You must create a different waveform and sequence data for the pulse trigger mode.

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

Can I renew or extend the 30-day trial license after expiration?
After the trial license expires on an instrument, it cannot be renewed or extended.

FAQ 2012-12-28

Is the performance of 0.4% EVM for 160 MHz 802.11ac best test result or average performance for N5182B MXG or N5172B EXG X-Series signal generators?
0.4% EVM is characteristic data of a small sample of N5182B MXG signal generators using the PXA and VSA 89601B.

FAQ 2012-12-26

Is the channel correction a new feature?
No, it has been available on the MXG since 2009. However, the functionality in the X-Series signal generators has been significantly improved since the first-generation MXG implementation.

FAQ 2012-12-26

Are there any S1 S2 measurements with power sensors on the X-Series signal generators?
No, however, the “User” channel correction routine in X-Series vector signal generators measures DUT channel response in phase and amplitude with power sensor.

FAQ 2012-12-26

Is there SCPI code compatibility from the 8662A or 8663A to the X-Series signal generators?
Yes

FAQ 2012-12-26

Which USB power sensors are supported on the X-Series signal generators?
All Keysight U200xx USB power sensors are supported. in the future, ...

FAQ 2012-12-14

For waveform 5-pack licenses, what alternatives are available for customers that require additional waveform evaluation time after the initial 30-d...

FAQ 2012-12-13

For waveform 5-pack licenses, can the customer download a waveform generated with the 30-day license?
Yes, if a waveform was created using the 30-day trial, it can be downloaded to any MXG/ESG with unused waveform 5-pack license slots.

FAQ 2012-12-11

Is there a 30-day trial license for this application?
Only selected Signal Studio software applications have the 30-day free trial license available, while others allow a free evaluation of the software interface only.

FAQ 2012-12-11

Can Keysight provide a location accuracy specification for the Option 409?
Unfortunately, Keysight cannot provide a location accuracy specification because this is dependent on the GPS receiver.

FAQ 2012-11-21

How do I obtain the NMEA GGA message file of trajectory information in order to create a dynamic scenario for a moving GNSS receiver?
There are several ways to do this...

FAQ 2012-11-21

How much baseband memory do I need in the ESG/PSG for opt. 422 scenario generator?
The scenario files reside on the hard drive until one is selected for playback, and then it is loaded into the baseband memory.

FAQ 2012-11-21

How does the N7609B calculate the total output power in relation to the number of visible satellites during a scenario?
When you initially turn on the simulation, the Satellite Settings page will update the “Power” column to show the power of each satellite in dBm.

FAQ 2012-11-21

Are scenario files compatible between the E4438C-409 and the N7609B?
Yes, the N7609B can use any of the scenario files created for the E4438C-409...

FAQ 2012-11-21

When simulating a signal that includes GLONASS and Galileo my receiver is reporting different satellite IDs than shown in the Signal Studio, why?
While GPS satellites are commonly identified by the pseudorandom codes (PRN) that they use, there is no industry standard yet for how to refer to the GLONASS or Galileo satellites.

FAQ 2012-11-21

I’m using the N7609B with an X-series signal generator. Can I generate a real-time GNSS signal without being connected to Signal Studio?
Yes, if you are using a stored scenario file, but not if you are using continuous scenario generation mode.

FAQ 2012-11-21

How do you calculate the individual output power of each satellite?
The ESG/PSG power level is distributed equally among the satellites.

FAQ 2012-11-21

How much baseband generator memory is needed in the signal generator to use basic mode waveforms?
The amount of memory that is needed depends on how many waveform files you need to have in the instrument memory at one time.

FAQ 2012-11-21

What is the maximum sampling rate for the GNSS waveforms?
The sampling rates vary depending on which constellation is being simulated, and they range from 2.044 MSa/s for GLONASS up to 24.552 MSa/s for Galileo.

FAQ 2012-11-21

What is the data content in the single satellite waveform files? Is it real navigation data?
The waveform files contain alternating 0s and 1s for the data. Real navigation data is not included since it is impossible for a receiver to calculate a location fix using only a single satellite signal.

FAQ 2012-11-21

Where can I find additional scenario files?
There is a link for additional scenario files on the product Web page for the E4438C-409 that takes you to this page...
