We just have a question about the devices used in the calibration for the power line and the data line.
Here under are the screenshots of what we have put in RadiMation:
• Configuration of the Calibration cable used into the Absorbing clamp:
The following ones are the Calibration setups described in the CWS500N1 data sheet:
• Power Line:
• Data Line:
We didn’t understand which devices we have to put in the test sites of the power line and data line.
1. For the power line and the data line, did we insert the correct devices in the test sites?
2. Is it necessary to insert the calibration jigs R100N for the data line too or Radimation already take into account for a 150ohm load?
3. Why can’t we insert more than one calibration jig in the test site (please note that, like showed in the picture, for the data line with the absorbing clamp there are 2 calibration jigs R100N to take into account)?

Re: calibration for the power line and the data line
The CWS 500N1 has an internal Monitoring, Forward and Reflected power meter. In the datasheet image, this is not shown.
Please add the internal used coupler. Add an additional CWS500N1 device driver configured for forward power measurement, and add it as Forward power meter in the test-site. See device configuration below Note that the Sensor power meter: em test CWS500N1 device driver must be configured to use the Monitoring setting. So the correct internal powermeter I used.
So preferably, remove the em test CWS500N1 configured device driver, and Add 2x CWS500N1 described as CWS500N1 Forward power, CWS500N1 Monitoring power.
In advanced option of each device, the correct power meter setting (forward/monitoring) must be set.
The total JIG should be set to 9,5 db for 150 ohm. In RadiMation the jig is defined as the whole setup. In your case, it is build out of multiple parts.
In your case the used internal resistance is 150 ohm.
The attenuation for the monitoring power meter should be set either as a calibration for the sensor power meter,
Or as separate cable at “current -> power meter”
The “Cable amplifier -> Coupler coupler” should be removed. For the calibration it is irrelevant.
Correct. Only 1 jig should be present for both test sites containing factor of 9.5dB.
2. Is it necessary to insert the calibration jigs R100N for the data line too or Radimation already take into account for a 150ohm load? Not necessary.
3. Why can’t we insert more than one calibration jig in the test site (please note that, like showed in the picture, for the data line with the absorbing clamp there are 2 calibration jigs R100N to take into account)?
