Calibration Block

The Calibration block offers full control over the loss and gain from all connected loads to Rx1 and Rx2:

Calibration Block

Left hand side Input:

  • RF

Right hand side Output:

  • RF (calibrated)


You can add the following varying loads to the calibration setup:

  • Antennas (All Aaronia antennas)
  • Amplifier (All Aaronia RF and NF Amplifier)
  • Cable (All Aaronia cables in different lengths from low cost to high end)
  • Attenuator (10, 20, 30 and 40dB)
  • Probe (All E and H probes from the Aaronia Probe Set)
  • Custom (Add you own calibratioin curve e.g. by loading a saved reference/calibration trace)
  • Power Offset (Any value between +/- 100dB in 0,1dB steps)

In addition you can also add a GPS position incl. azimuth and declination:

All loads will be shown with there corresponding gain/loss as a graph.

All loads together will be calculated to a new overall calibration shown as a grey graph:

We added an Elevation value to the Calibration block:

We added a checkbox to the Position Configuration so you can enable the data position data feed:

V6 RSA is default calibrated >10 MHz, with optional calibration at 1 MHz. However, since the receiver circuitry works >9 KHz, is it possible to have it calibrated at 9 KHz, or at least 300 KHz on request? What would be charged for the service?

Is it possible to calibrate at the user end, using the calibration block? If so, please explain the steps/mission setup.

Yes we can offer a "low frequency" calibration for 350 Euros including a calibration dataset which you can import to the Calibration block. If you already bought the V6 you would need to send the unit back to us.


ALPS has reacted to this post.

So with low frequency calibration the RSA250X will provide accurate measurements at 9 KHz?

Yes but as you can see in this posting screenshot the sensitivity will be quite poor since you are operating the unit far from the specs.
