Gain blocks installed |
|
|
Jordan will write up the detailed elog but in summary,
- Former +24V Sorensen in the AUX OMC power rack (south of 1X2) has been reconfigured to +12V DC.
- The voltage was routed to a bank of fusable terminal blocks on the NW corner of 1X1.
- An unused cable running to the PSL table was hijacked for this purpose.
- The ZHL-1010+ were installed on the upper shelf of the PSL table, the two gain blocks draw a total of ~600mA of current when powered.

I will install these at the next opportunity, so that we can get rid of the many attenuators in this path (the main difficulty will be sourcing the required +12V DC for operation, we only have +15V available near the PSL table).
