Includes SMA connector and cable to Receiver Module
Does not include GPS Antenna 2000-1528-R
Procedure
Opening the Case:
1. Open the case as described in Section 7-16 “Opening the Instrument Case”.
Disconnecting GPS Antenna Cable:
2. Disconnect the GPS Antenna SMA connector from the top connector panel by performing the following
sub steps:
a. Use two 5/16 inch ( 8 mm) end wrenches to disconnect the GPS Antenna SMA connector (item 11
in Figure 7-18 on page 7-38) from the top connector panel.
b. Pull off the nut and lock washer and remove the SMA connector from the top connector panel.
c. Replace the lock washer and nut onto the SMA connector for safe keeping.
d. Route the cable to the right side, clearing its notch and the top connector panel, so it is clear of the
VNA PCB Assembly and the Case Front Assembly.
Removing Cables:
3. Cut the cable tie (if used) that holds the Ext Trig Input (item 1 in Figure 7-18) and Ext Ref Input (item 2
in Figure 7-18) coaxial cables to the RF Out semi-rigid coaxial cable.
Identifying VNA PCB Assembly Mounting Screws:
Figure 7-22 shows model MS2036C. All steps to remove and replace the VNA PCB Assembly are the same for
MS2036C, MS2037C and MS2038C instruments. In model MS2037C and MS2038C, the microwave module
replaces the 2 semi-rigid cables. Refer also to the microwave module, item 15 in Figure 7-7 on page 7-9.
4. Using Figure 7-22, identify the locations of the eight (8) Phillips-head mounting screws that hold the
VNA Assembly PCB in place. Figure 7-20 on page 7-40 shows the 8 hexagonal standoffs on the Mother
Board. The 8 VNA Assembly PCB screws attach to the 8 hexagonal standoffs in the Main PCB (Mother
Board). The general locations of the 8 hexagonal standoffs are also visible in Figure 7-4 on page 7-6 and
Figure 7-6 on page 7-8.
