The New York Minutes

Hello to all from Western New York! I had hoped to include an equipment evaluation this month on my new LG Technologies LPT-3000 spectrum
analyzer, but I have not had the time to adequately put this new piece of test equipment through rigorous testing. I did, however, use the analyzer recently side-by-side with the corporate Anritsu spectrum analyzer while setting up the nighttime IBOC for WLGZ, and the two reported similar results. In a nutshell, I found the LPT-3000 very easy to use, and navigation through the system menu was easy. The one function I found very easy to use was the Occupied Bandwidth Measurement, which gives you a pass/fail indication right on screen. Perhaps next month I will be able to give a full, detailed report on this analyzer. The only negatives I have found so far are that the analyzer will not accept a modulation sample directly from the transmitter without using an external attenuator, and that the unit does not come with a printed user’s manual (it has the manual in PDF format on a CD-ROM).
