7-25 Installing Main PCB and Reassembling Instrument Assembly Removal and Replacement, MS203xC
7-70 PN: 10580-00307 Rev. D MS20xxC MM
12. Make sure that the top connector panel (part of the VNA PCB Assembly) is correctly positioned and then
fasten the VNA PCB Assembly into place by using eight (8) Phillips-head screws. Torque these screws to
7.5lbf·in (0.85N·m).
Installing GPS Antenna Connector:
13. If the GPS Receiver Module (Option 5) is not installed, then skip ahead to Step 14. Otherwise, perform
the following sub steps:
a. Route the GPS Antenna cable from the Main PCB so that it is located between the top connector
panel and the VNA PCB Assembly and routed into its notch
1. Connector J3000, 40-Pin, for ribbon cable to SPA PCB
2. Connector J5010, Twiddle connection for rotary encoder
3. GPS PCB (Option 31)
4. Connector J4202, for multi-conductor signal cable to LCD display
5. MMCX Connector J3203, 140 MHz IF (connects to SPA PCB at J4004)
6. MMCX Connector J3202, External Trigger (BNC connector on top connector panel)
7. MCX Connector J2201, 26 MHz Out (VNA reference, connects to J7002 on upper shield of VNA Module)
8. MMCX Connector J2200, 100 MHz In (connects to SPA PCB at J6002)
9. MMCX Connector J2202 (not used)
10.Connector J1003, Battery connection
11.Connector J1002, Fan connection
