Replacing the 8508A vector voltmeter with the E5061B network analyzer
Measuring the phase difference of an external CW signals is a typical measurement application of the 8508A vector voltmeter.
FAQ 2013-04-25 |

|
How much jitter is there when using an external trigger?
Unless the trigger signal is synchronized to the Arb sample clock, you will see jitter equal to the sample period for the internal Arb and equal to 8 sample periods for the N6030A.

Is it possible to adjust the phase offset using degrees instead of radians?
Yes. Select View -> Customize Pattern Item Table and toggle the ‘phase offset in degrees’ button

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.

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

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

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.

Where can I find GLONASS almanac files to create custom scenarios?
You can obtain GLONASS almanac files from this URL: ftp://ftp.glonass-iac.ru/MCC/ALMANAC.
FAQ 2012-11-21 |
|
|
Why does my GPS receiver not show the correct year that I’m simulating?
The GPS date is expressed as a week number and a time-of-week value. The week number is transmitted as a ten-bit field in the C/A navigation message. It can therefore signify a week within a period of 1,024 weeks or 19.69 years.

Where can I find Galileo almanac files to create custom scenarios?
There are no official published almanac files at this time for Galileo. The N7609B software includes a default almanac file, 20110709_Gal.alm
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 |
|
|
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 |
|
|
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 |
|
|
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 |
|
|
Is there a way to transfer sets of waveforms to each signal generator without having to connect the N7609B software to each instrument?
Yes. All of the waveform files are available on your PC when you install the N7609B application; they are in the application SW folder
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 |
|
|
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.
