Hi Howard,

I took the liberty to fix some of the formatting in your previous post.
For future reference, using the <code> tag is a good way to avoid formatting issues when posting code.

I wonder if your issue may be related to how you have set the write termination for your VISA connection as I have not faced the same issue, I am able to, using the Python script I previously shared here, send a cosine waveform (not ending or starting with 0) and have it received without issue.

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.

Hi Xiang,

This usually happens when an *IDN? query was sent but no corresponding VISA Read was transmitted. Because of this, the response to the query is held in the IO buffer until it is read in the next query.
The solution is to call VISA Clear at the start of your program or before your query.

Hi Philip,

The OS restore will depend on your serial number:
B010xxxx - 063-3693-01
B020xxxx - 063-3759-02
B030xxxx - 020-2880-01
B050xxxx and up - 020-2970-02

I believe you should be able to order at least some of these directly from us.
To order a part call 1-800-833-9200 opt 1.

Hi Javier,

I would suggest working with IF samples instead of IQ data, as these take a lot less processing from the RSA, therefore potentially speeding up your transfer.
If you still need the IQ data, then you can calculate in on the PC side with a much faster processor in parallel, avoiding the bottleneck of IQ demodulation.

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.

Hi James,

The "Source" drop down menu is in the "Measure" menu. See the picture attached with this post.
From there you should be able to select channel 1 and then SV_Normal.

I do not believe you need any licenses or add-ons to see SV_Normal measurements. Just ensure that you have the latest software version installed (1.44) and you should be able to see it.

Hi James,

If you have spectrum view enabled for channel 1, then you should be able to go into Source, press Ch1 and see Analog and SV_Normal has options. SV_Normal is the source you want for the channel power measurement.

Hi James,<br> <br> You should be able to be able to create Spectrum View measurements if you change the source to "Ch_1_SV_Normal" (in case of channel 1 spectrum view). Then, you can select channel power and configure the channel width (the center of the channel is the center frequency of spectrum view).<br> <br> In terms of SCPI commands, this can be done with <code>MEASUrement:ADDMEAS CPOWER</code> and then you can use <code>MEASUrement:MEAS<x>:ABANdwidth</x></code> to set the desired bandwidth.

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.
