DDRParticipantHi guys,
I have following query,VSG60A is connected to a Signal Hound SA124B, swept 100MHz to 6GHz at -20 ref level and 50MS/s.
For each frequency, we get the corresponding peak height from the SA.
Kindly find the screenshot as an attachment.
It appears that we have a significant loss in power near 6GHz and near 500MHz.Please advise on what can be done to remedy this.

Justin CrooksModeratorDDR,
You should not have big dropouts like that. This would indicate either hardware failure, bad correction data, or possibly bad sweep settings resulting in bad measurements.
To rule out the sweep settings issue, please test individual failing points with the VSG in CW mode, and the SA124B set to a 200 kHz span centered at the output frequency. You can email support at signalhound dot com and we can try to figure out if we can fix it with correction data or if we will need to repair one of the units.
DDRParticipantThank you for the information.

Hi justin,
With reference to previous conservation, It seems like there is some 10dBm power inconsistency across the frequencies.
Kindly find the screenshots of readings for the individual plots from the SA at 500MHz to 5.5GHz and an overall plot as an attachment.
Please suggest the solution.
Looking forward your feedback.Attachments:

DDR,
Have you reached out to our support department yet? (support@signalhound.com) We will need to run through our troubleshooting process, and if we can’t fix it remotely we will need to troubleshoot one or both units here.- AuthorPosts
