How can the settings of an oscilloscope for the the Voltage measurement during a Conducted Immunity be set?
I'm trying to setup a conducted immunity test with the attached setup.
The test goes from 100kHz to 50Mhz.
I'm using the constant voltage setup with a constant Voltage of 1V.
But I wonder how the DSO is configured (because I see no controls in the test setup). Does RadiMation automatically controls the timebase, amplitude, detects the channels, trigger, etc? or do I have to set those controls manually?
Oscilloscope configuration during a CI Voltage test?
Re: Oscilloscope configuration during a CI Voltage test?
Hi,
A Conducted Immunity fixed Voltage test can be configured using the following configuration:
The 'Constant Voltage' testlevel configuration can be configured lik:
The 'Measuring device' setting specifies which device is used for the measurement of the Voltage. In the above situation the Oscilloscope will be used, which is the device that is selected as the 'Oscilloscope' in the selected testsite ('Virtual') on the TSF window.
No further configuration of the Measuring device (the oscilloscope) is necessary. RadiMation will automatically set the correct timebase, and amplitude settings.
Depending on the physical measurement device for the oscilloscope that is used, it may be possible that input selections can be configured in the device driver.

Re: Oscilloscope configuration during a CI Voltage test?
I'm trying to use the conducted immunity - fixed voltage setup, measuring voltage with a Tektronix TDS2024 oscilloscope.
- Should I use a x1 probe? x10 probe?
- To which of the four channels of the oscilloscope should I connect the voltage probe?
- I tried connecting a x10 voltage probe to channel 1 and also to channel 2 and have no success.

Re: Oscilloscope configuration during a CI Voltage test?
It should not make a difference if you are using a x1 or a x10 probe. This difference in the used probe is very often detected automatically by the oscilloscope, and also being corrected by the oscilloscope. The values that are being returned by the oscilloscope to RadiMation are thus already correctly adjusted for the use type of probe.
The RadiMation device driver for the Tektronix TDS2024 is by default using input 2 of the Tektronix TDS2024. So it is best to connect it to the second input.
Assuming that you are performing a CI voltage test on 1V, starting at 100 kHz, RadiMation will control the Tektronix TDS2024 using the following steps:
The setting of the amplitude and timescale is thus automatic depending on the measured frequency, the expected voltage and the currently measured voltage.
I hope this provides you with some more information on how the measurement procedure is working.

Assuming that you are performing a CI voltage test on 1V, starting at 100 kHz, RadiMation will control the Tektronix TDS2024 using the following steps:
- Reset the device: *RST
- 1 byte return size: DAT:WID 2
- ASCII format return: DAT:ENC ASCII
- Enable input 2: SEL:CH2 ON
- AC Coupling: CH2:COUP AC
- Edge triggering: TRIG:MAI:EDGE:SOU CH2
- Set measure time (1 / freq[Hz]) => 10 us: HORIZONTAL:SCALE 10E-6
- Set voltage scale (70% of the expected peak voltage): CH2:SCA 1.4
- The number of points are determined: DAT:STAR? and DAT:STOP?
- Measurement trace is requested and transferred to RadiMation: CURV?
- Each sample is squared and added, and divided by the number of samples, to get the corresponding RMS value.
The setting of the amplitude and timescale is thus automatic depending on the measured frequency, the expected voltage and the currently measured voltage.
