| Advantest R3477 9kHz to 13GHz spectrum analyzer |
| << < (7/12) > >> |
| nctnico:
I have found some files which seem to have calibration data in them in the C:\Advantest\R3477 directory on the disk. |

Did you ever check your analyzer in the range above 3.5GHz? Is it accurate there? I've made a table with my measurements and attached it. Also coud you check the values of your YTF Tune adjustment in the service menu because mine reads 0 for parameters 1 to 6 which I find odd thanx |
| nctnico:
Can you post a picture of which settings you are referring to so I can make sure I'm looking at the same? BTW I found something odd: the frequency calibration file on my R3477 goes to 15.4GHz and it is indeed possible to select frequencies up to 15.4GHz! |

Hi I used a R&S ZNB8 network analyzer as signal source and compared the measured signal between my R3477 and a R&S FSP analyzer Settings were ref +10dbm attenuation 20db span 100MHz and RBW=VBW=1MHz Signal was 0dbm. I measured the peaks with a marker and put them in a table. And as you can see from the measurements at around 6GHz there is quite a discrepency between the measurements. |

Oh sorry i realised that you meant the YTF settings :palm: and i saw that you have to go to the band select menu to change between the ytf harmonic modes. and only the base band has TC whereas the H1,H2and H4 have parameters 1 to 6 Also if you select H4 band the setting of the upper screen is centered at 15.2GHz. So it seems tha calibration goes beyond what the analyzer is officially working anyway here is the picture |
