I have a Hewlett Packard E4420B / Agilent Technologies 250 kHz to 2.o GHz ESG Series Signal Generator for sale. It will go as low as -135.000 dBm This works as it should. I accept credit cards through PayPal. I am in need of a new 15 HP boat motor for my dinghy on my sail boat. We are leaving for a 6 month cruise on our sail boat (Spirit Of Ol Henry 2) on November the 3. This is the only reason I am selling this equipment. kf4eok / ham / amateur I will not deal with scammers unless I get paid three times the selling amount and I will hold the item for 420 days after the funds clear, then If I still have the item I might release it to you if I feel like it.
