S-band system installation summary November 2008

1. 6 BPM processors installed
2. Processor 4 is set to work with the reference cavity (2834MHz)
3. Additional units include: LO distributor, breakout box, power supply
4. All processors and the breakout box are powered by the power supply and connected to it by 5-way XLR cables at the backplane, LO distributor has an independent built-in PSU
5. Cables from the BPMs come to the N-type patch panel, see the table below The whole RF cable plant is a temporary installation and needs to be replaced by lower loss cables (currently ~14 dB att), that probably means using another (new???) penetration hole
6. Processors are currently connected as:
   • ch1 - MSF1FFx - processor2
   • ch2 - MSF1FFy - processor3
   • ch3 - MQF1FFx - processor7
   • ch4 - MQF1FFy - processor8
   • ch5 - MSD0FFx - processor9
   • ch6 - MSD0FFy - n/c
   • ch7 - MQD0FFx - n/c
   • ch8 - MQD0FFy - n/c
   • ch9 - reference (not installed yet) - processor4
   • ch10 - spare cable number 13
7. The LO source (borrowed from SLAC, has to be returned) is to be set to 2856 MHz 0 dBm, the level at the output of the distributor is then ~1.5 dBm
8. The electronics can be controlled using LabVIEW program running on the control PC.

HOST: sbpm

On the desktop there is a "bpmcontrol" icon double-clicking which one would bring up the control software. The attenuation and the control voltage on the LO amplifiers can be changed.

1. 4 more processors (now fully tested), additional PSU, calibration system and the reference cavity to complete the installation are due to be shipped in late January.

S-band electronics - operational instructions

1. Make sure the outputs of the electronics (BNC connectors) are either terminated or connected to a 50 Ohm load. Running without a load may damage the electronics.
2. Turn on the power supply, the neon light in the rocker switch on the PSU, as well as +5V and +24V indicator LEDs on the PSU and all the processors should be illuminated
3. Turn on the LO distribution unit, check that the neon light and the +12V LED are illuminated
4. Set the LO source to 2856 MHz, 0 dBm, turn on the RF output
5. Start the control program on the PC double-clicking "bpmcontrol" icon, LabVIEW should start up and you should see the interface of the control program (similar to the one shown below). Start the program, clicking LabVIEW's run button (a thick arrow in the top-left corner of the window, the arrow becomes filled).
6. Set the control voltage of the LO amplifiers ("Amplifier Volatge") to 5V (don't forget to click the "Set" button), you should be measuring +5V at the 4 right-hand BNC outputs (AO0..3) of the breakout box, these must be connected to the "AMP" BNC connectors on the processor boxes.
7. The system should be working, you can set the attenuation individually for each processor typing in the value in "Attenuator (set)" and clicking it's "Set" button
