Hi Albert..probably I put some meters of RG147 as fixed(solder) internal
line
in order to obtain a 100nS pulse width.
What is the secret about this GR connectors ?, I have the temptation to
replace by a BNC, any wrong with this change?.
Gabriel.
My version of this generator has a fixed solid line coiled up inside. There
is also a front panel SMA to attach more line if needed.
Nothing special about GR connectors. Essential if you have a lot of GR
gear; they were really GR's solution to a 5GHz connector, introduced in
1943. Then later they introduced the GR900 series that went higher in
frequency. Both "hermaphrodite" in that there was not a male and female
connector - everything was identical. There were lots of in-house
connectors designed - anyone remember the Rhode&Schwarz Dezifix? All
superceded by the N-type for this frequency range. But really, a high
quality, branded BNC would be fine (all BNC's are not created equal!)
