LED XLR cable tester?
Today my professor showed us how to set up a LED XLR cable with a 9v battery, a switch to test each of the three needles, a LED that will light up if for when each of the three needles in the cable are working when they are touched, and a resister thats 360 Ohms.
For homework he wants us to figure out a set up: Can’t use a 9v battery, no switch (have to test all 3 of the needles in the cable at once, hooked to a 80 Ohms LED, and with no resister.
I am stuck and would appreciate any help, Thank you.
It is hard to figure out what the exact assignment is…does he want you to build a tester that tests the continuity of XLR mic cables using only an LED? That is basically impossible – you need some type of voltage to make the LED light up no matter what.
If you have an audio mixer nearby, you could use the phantom power produced by the mic input channel to light the LED but you still will need a current limiting resistor. That would work but I don’t know if that fits what the assignment is. The phantom power puts 48 volts dc on pin 2 and 3 of the XLR cable.

Optimized Portable TDR Cable Fault Locator from GAO
Toronto, Canada - GAO Instruments (www.GAOInstruments.com) announced its portable and easy-to-use time domain reflectometer (TDR) Cable Fault Locator (GAODS6110), which is used to locate RF cable faults such as short circuits, open circuits or high resistance joints or splices. The TDR test instrument determines cable faults by transmitting an electrical energy pulse that propagates with specified speed depending on the cable type. Upon analysis the fault locator automatically displays the fault type and distance to the faults.
The TDR cable fault locator has a maximum test range of 1200 meters and can be used to calibrate cable type following a few simple steps as indicated on the device’s screen.

where can I buy a signal tester to check if the Comcast signal is working?
My house is networked and I need to test the Comcast Digital Cable signal in each room. I went to Radioshack in San Jose, CA off Branham but they don’t sell them.
It’s really BEST to have Comcast run the tests FREE OF CHARGE.
But, if you want to do a Quick Continuity Test, just plug in your TV on the RF cable…after that the Cable modem takes over and delivers the networked Digital Signal to your computer….if you have Cable TV you’ll have Digital Comcast there too….TVs won’t pick up the Digital signal, but we’re testing for bad signal path and a snowy picture on Channel 3 or 7 or any channel will show the cable quality in each room….CLEAN PICTURE means a good connection.
