10MHz Ref On Your Bench - Do You Need It?!

https://www.youtube.com/watch?v=dSorllr83nE

I forgot to show how you switch the 10 Mhz Input / Output: Press Utility, RefClock, to select the desired clock type.

This is a great deal if you want a scope with a 10MHz Reference input:

Normal retail: $2499, at this link: $925 with free shipping and there is a coupon code for a further $50 off.
In this video I talk about the benefit of having a a 10MHz Reference on your bench for your Oscilloscope, Frequency Counter and Frequency Generator.

General Discussion / HELP

« Last post by cossy350 on January 21, 2020, 02:00:53 PM »

Hi everyone I wonder if you could help me out

I have a low amp clamp which are used for parasitic drains on a battery for automotive use but obviously it is very sensitive and it is picking up interference all around I was wondering if there's any type of tape I can put on the outside of the clamp to stop interference or is there anything else I can do to try and stop as much outside interference as possible so when I put it over the cable I am just getting a true Reading from the cable and not interference everywhere else

What I was thinking of doing as you can see from the picture on the black clamps is putting some sort of shielding tape on the outside but I don't know which is the best stuff to use if anyone can give me any ideas it would be much appreciated thank you

T4D #142 - Blown GPS Disciplined Oscillators and Chit Chat

https://www.youtube.com/watch?v=iMywMpxMdjI

I managed to blow two of my GPS Disciplined Oscillators. I explain how that happened and what you can do to avoid it.

I also talk about the DIY bench power supply project which is underway again.

I give an overview of my project on building a cheap high accuracy quartz clock. If you are looking for a cheaper / lower priced but excellent Low-jitter GPS-locked precision frequency reference (GPSDO):

Oddball #1 - Vici VC8145 Dual Display Bench Multimeter

https://www.youtube.com/watch?v=xvhpIeDkPu0

A "quick" overview of the Vici [Vichi] VC8145 Dual Display Bench Multimeter. This is an oddball as it has a fair amount of functionality and provides 82,000 count resolution and a fairly cheap / low price compared to other meters. A great written review on this meter:
