Re: External Time Base T5829A for Quantar
Voltage divider would work equally well for 5MHz. One issue is the 5829 has 8 BNC connections. I was wondering if there was some malfunction as I don't have the specs for it. Also could the output be reset to some lower value. I would like to know more about the 5829A. It is one of the very few piec...

Re: External Time Base T5829A for Quantar
Closer than I thought. Still taking readings. On a quick check what I saw with a 50 ohm jumper was about 5.2 V RMS. Still little high.
Repeater arrived this afternoon so I will be testing and measuring with actual repeater.
Really appreciate answer. Want to make sure I don't damage repeater.

We have about 25-30 Spectras in our 900 MHz community. My exitsting head is a HLN6075C SP07 with a HLN6285A back/connector board. Th...
