Aritsu VNA-DL 1-8800 MHz

[porous]

Hello all,

I recently bought the Aritsu VNA-DL 1-8800 MHz for around 400 USD plus tax/customs from Russia and would like to share some results:

- measures S11 and S21
- plastic housing, doesnt get too warm, calibration seems to be quite stable over time

- measured output power varies from - 20 dBm to -10 dBm. At 8800 MHz it is down to -30 dBm.
- I calibrated using SOL+T method, result is nice but if I measure short behind a short coax cable I see ripples that were not able to remove by adding an electrical delay
- measured short behind a long cable (1m) and the ripples grow...
- measured a 3 dB attenuator in S21 without adding a cable, see some ripples
- Software has the basic functions but doesnt allow to zoom in more than 5 dB.

My guess is that for 400 USD they use a wheatstone bridge as coupler which limits the calibration performance.
But 400$ for a 8.8GHz VNA....

Cool!

I've seen these marketed as "ARINST," which seemed strange, but now that I see "Aristu" and Anritsu green in the graphs, it all makes sense, lol.

Is it using harmonics to get to 8800MHz or is that fundamental?

Thanks for sharing

They use harmonics. The mixers are specified up to 6 GHz only.
