Dear Sir,
Please find below my Requirements:
- We have a Signal hound SA44B Spectrum analyzer and i need to calibrate this SA with Keysight E4433B Signal generator using Ext 10MHz out clock signal.
- The Frequency measurement accuracy of the SA44B spectrum is + 1PPM.
- I need to improve the measurement accuracy of SA44B Spectrum Analyzer by providing External 10MHz Clock from the E4433B.
- I need to perform the RF frequency measurement accuracy test on a 433MHz frequency band, So for that, I required to reduce the Frequency measurement resolution + 20Hz.
- I have gone through the documents of SA44B and found the following specifications of the external 10MHz clock.
I have checked in the user guide of Agilent E4433B ESG-D series signal generator that it has external 10MHz Clock output.
Queries:
- Can we utilize this 10MHz out the clock for the signal hound SA44B time base reference clock to improve the measurement accuracy of my SA?
- I am not an expert regarding this, but can anyone suggest to me the preferred GPS Disciplined Clock oscillator board if the above method does not work?
I request you to guide me regarding this further.
Thanks and regards,
Sagar Mistry
Hi,
based on a picture of your E4433B, you don't have option 1D5 high stability 10MHz reference, your requirement it's a precision of ±20 Hz at 433MHz, you need a precision of ±0.046ppm, the precision would be ±0.05ppm or better with option 1D5. You don't have this option 1D5, maybe it's would be better to use a GPS Disciplined Clock oscillator board or any good OCXO.
I found any phase noise specification for your SA44B Spectrum analyzer, I think the performance is low, it's normal for the price and size of the device.
Phase noise for E4433B, for your 10Mhz reference, it's the STANDARD curves PN1 and PN2 (from FREQ menu page 2/2).
