Hi Hendorog,

Thank you for the suggestion. I will try it.

Ones again, thank you.

Hi Andrew,

Thank you Andrew for a very quick reply. I’m sorry that I did not reply sooner, quite busy at work. I downloaded spike version 3.0.7 and so far I did not have the issue of SA and TG disconnected in the middle of the measurement. Thanks a lot guys.

Ones again thank you for the latest spike version.

Sincerely,
Mervin

Hi AJ, I did encountered this issue yesterday when I first turned on my unit. The solution is installing the usb driver included on the spike software package download. I am now using it without any hitch so far.

Regards and hope you will soon able to use your unit as well.

Hi Bruce, I’ve learned from your distributor in Singapore that your company is working on model BB2… something which has a bandwidth up to 20Ghz. Please comment. This model will be potentially a good addition to our company R&D laboratory.

Thank you, keep up the good work and hope you will maintain and still position your products to be available for the masses.

Thank you ones again.

Hi Bruce, thank you for the suggestion. I’ve just received the units yesterday and started working on the SA using the latest version of SPIKE. So far so good. I haven’t got around to try on the TG.
My first impression, good product and potentially great.

Thank you and I hope you and your team will continue to support users such as myself to get the most of your products capability.

Thank you.

Hi Bruce, Thank you for the great news. I’ve already ordered USB-TG124A and USB-SA124B OPTION 2 from one of your Authorized Distributor (DT techsolutions Pte Ltd) here in Singapore.

I downloaded the SPIKE software in preparation for the units arrival. I also went through the forums and got lots of positive comments. I had read the USB-SA124B manual and found out that the SPIKE software doesn’t support the Smith Chart Utility anymore. I have to bring this up since it’s critical to my work. I’ts one of the main reason I actually very interested in your product. Is there anyway this feature can be included on next software update?

Thanks a lot.

Hi Justin,

Great! this would be very help full in my work. One more thing. Can you able to elaborate more the difference in terms of performance of having precision 10 MHz time base of USB-SA124B compared to the normal USB-SA124B. Any limitation in USB-SA124B that you can point out when using 10 Mhz time base on the USB-SA124B (without option 2).

Thanks a lot for the reply.

Regards,
Mervin

Hi Justin, thank you for the info. the new firmware will be worth the wait. I should also mention, will the new release include spectrum mask pass/fail measurements? We usually check if the spectral mask of our product IEEE802.11a/g waveform with 54Mbps, 64QAM will conform with FCC/CE requirements.

Thank you.

Hi Justin, many thanks on the reply. I am considering purchasing USB-TG124A and USB-SA124B OPTION 2. I was contemplating on purchasing BB60C but since I need to perform loss measurements and impedance matching in cable as well as PCBA level, not to mention EMC pre-compliance testing on current products as well as upcoming products and yes our company is on a tight budget with regards to test equipment’s.
Anyway, can you help me my queries.
1. Can you provide info as well as limitations when doing occupied bandwidth, channel power, adjacent power, harmonic distortion measurements on a 2.4Ghz and 5Ghz wifi signal. At least on its lowest data rate (a/b/g). I understand constellation and EVM related measurements are out of the question with regards to these models, but I can live with that.
2. Any limitation when measuring frequency response on filters with 1Ghz bandwidth. We need it to optimize discrete balun filters in the entire channels of 2.4Ghz as well as 5Ghz band.

Thank you and looking forward on your reply.

I’m working as an engineer in a local R&D company doing WiFi products, my job involves optimizing and debugging RF front end of our products. The capabilities of the BB60C is major plus but would be greatly expanded with a tracking generator that goes along with it.
