EMC with BB60C, TG124, ZHDC

Hi,
I’m new with Signalhound and received above components a few days ago for testing mainly pre-compliance ability.
I have some questions:
a. regarding EMI I’m used to have the SW tracing the full span and after to go automatically into detail at all spurs with QP detector, having all of it defined in compliance-according setups (dwell time etc.). I can’t find that in Spike, how do I setup?
b. how do I setup a certain number of measurement points per range (CISPR conform)
c. EMC: how do I setup TG to sweep over a specific range with specific dwell time and specific steps? How shall I connect TG with BB & ZHDC to my wideband amp (connected to the TEM cell)

thx.

Hi gga33,

Thanks for contacting us. I can help you with your questions.

a. In our software switching between sweeps and QP detector is manually done with the Start/Stop buttons in the control panel under the “Meter Settings” tab. Additionally in the Peak Table control panel along the bottom of the screen, you can select a peak and move the settings to the QP detector by pressing “Selected Spur to Meter”. In the meter settings you can control the dwell time parameter.

b. The only way to change the measurement points in the sweep is to change the RBW. You currently cannot directly set the number of points in the sweep.

c. You will need to use the “Scalar Network Analysis” measurement mode in Spike for return loss measurements. There is a step-by-step setup guide in the manual (you can bring the manual up in the help menu). You can also watch the Justin setup up the software for SNA measurements in this video https://www.youtube.com/watch?v=hxUZx-9DMYg

Let me know if you have follow up questions.

Andrew

Hi,
thx. so far; the video helps a bit but I still have issues using TG for EMC purposes:
1. isn’t it possible to run the TG on it’s own by just setting start/stop/steps/dwell time -> this is necessary for EMC.
The scalar mode seems to be desgined for filter/antennas..

2. Using TG control panel I can’t see any change in the output level regardless what I try

Hello Gerhard,

1) We have two graphical ways to control the TG, either through the Spike software and through the application TGStandalone.exe found in the Spike installation directory at C:/Program Files/SignalHound/Spike/. Both ways only allow you to set the amplitude and frequency manually.

2) The output level on the TG is between -10 and -30.

Outside of the scalar mode, the TG is a simple CW generator. Yes, the scalar mode is primarily built around return loss and insertion loss measurements, filters and antennas being two of the larger use cases.

If you want to talk in more depth about your measurement requirements offline, you can email us at support at signalhound dot com.

Regards,
Andrew
