Adopter for SQPIN500X in order to Use IsoVu probe

I am a graduate student and trying to use IsoVu probe for my measurements. I have&nbsp;SQPIN500X extension on the probe, but I remain unable to connect it to my SMA connector. I was wondering if there is some mating part which needs to be connected between probe and SMA connector, or if there is some specific SMA connector which need on my PCB instead.&nbsp;<br> <br> Can someone let me know the package for the whole measurements, especially details about the connector that goes and gets connected onto the PCB?<br> Your prompt reply will help me a great deal. Thanks <script id="allow-copy_script">(function agent() { let unlock = false document.addEventListener('allow_copy', (event) => { unlock = event.detail.unlock }) const copyEvents = [ 'copy', 'cut', 'contextmenu', 'selectstart', 'mousedown', 'mouseup', 'mousemove', 'keydown', 'keypress', 'keyup', ] const rejectOtherHandlers = (e) => { if (unlock) { e.stopPropagation() if (e.stopImmediatePropagation) e.stopImmediatePropagation() } } copyEvents.forEach((evt) => { document.documentElement.addEventListener(evt, rejectOtherHandlers, { capture: true, }) }) })()</script>

Hi,

Those probe tips are meant for standard square pin connectors. We do not sell square pin to SMA adapters.

The probe tip attaches to the probe body through an SMA connector, so it might make more sense to get an SMA attenuator and cable to connect directly to the probe body, instead of going through a square pin adapter which might sacrifice signal integrity.

With that said, your use of the 500x 600 V attenuator with an SMA connector seems unusual to me, as that is significantly over what SMA is typical rated for. So I would ask for more details on the measurement you wish to make so I can better help you.

Thanks for the reply. I thought the probe can only be used with SMA connector, I stand corrected. I am open to using standard square pin connector for the measurements instead. Do you mind sharing the part number of standard square connector? It may be necessarily be made by you guys, but available commercially off the shelf would suffice.&nbsp;<br> &nbsp; <script id="allow-copy_script">(function agent() { let unlock = false document.addEventListener('allow_copy', (event) => { unlock = event.detail.unlock }) const copyEvents = [ 'copy', 'cut', 'contextmenu', 'selectstart', 'mousedown', 'mouseup', 'mousemove', 'keydown', 'keypress', 'keyup', ] const rejectOtherHandlers = (e) => { if (unlock) { e.stopPropagation() if (e.stopImmediatePropagation) e.stopImmediatePropagation() } } copyEvents.forEach((evt) => { document.documentElement.addEventListener(evt, rejectOtherHandlers, { capture: true, }) }) })()</script>

Hi Mustafeez,

The probe tip is meant to connect to square pins on a PCB.

If you wish to connect to SMA, I suggest removing the probe tip and connecting the probe directly to SMA.
Beware that without the probe tip you will have no attenuation and so your safe voltage range will be greatly reduced. You will need to add your own attenuation as necessary.

<strong><em>"The probe tip is meant to connect to square pins on a PCB"</em></strong><br> <br> That is exactly what I am looking for. Do you have to know the part number for those "<em><strong>square pins"</strong></em>? It would be much easier for me to buy them online.<br> <br> Thanks <script id="allow-copy_script">(function agent() { let unlock = false document.addEventListener('allow_copy', (event) => { unlock = event.detail.unlock }) const copyEvents = [ 'copy', 'cut', 'contextmenu', 'selectstart', 'mousedown', 'mouseup', 'mousemove', 'keydown', 'keypress', 'keyup', ] const rejectOtherHandlers = (e) => { if (unlock) { e.stopPropagation() if (e.stopImmediatePropagation) e.stopImmediatePropagation() } } copyEvents.forEach((evt) => { document.documentElement.addEventListener(evt, rejectOtherHandlers, { capture: true, }) }) })()</script>

Hi Mustafeez,

I am not sure, but it seems you are looking to buy the square pins themselves? Those are industry standard and available from many retailers.

As listed on page 5 of the datasheet for the IsoVu probe, we do sell spare pins under the part number 020-3169-xx.

These may not be the most appropriate for inclusion in a PCB.
