Removing the N5292A Option 200/400 from the System
Test Set Removal Procedure

2. Using a 5/16-in wrench, remove any flexible cables from the rear panel of
the system.
3. Remove the TEST SET I/O cable.
4. Using a 5/16-in wrench (and for the port connectors, use with a 20 mm
open end wrench), remove all of the semi-rigid cables from the analyzer to
the N5292A front panels.
5. Using a 5/16-in wrench, remove any 50 ohm terminations from the front
panels.
6. Using a T-20 TORX, remove the upper and lower locking feet.
7. Slide the analyzer forward to disengage from the lock link on top of the

Replacement Procedure
IMPORTANT!
The N52xxB interconnect kits contain 2.4 mm to 3.5 mm cables. It is
important to connect the 2.4 mm end to the PNA and to connect the
3.5 mm end to the N5292A test set controller. Improper connections will
result in damage to your instruments.
It is important to use two wrenches when connecting the semirigid cables
to the 1/2/3/4 port 1.85 mm outputs front ports of the PNA to avoid
stressing the connectors and causing damage to your PNA (i.e., the
2.4 mm cable end is compatible with the 1.85 mm connector of the PNA).
1. On the top side of the N5292A, carefully position the grey flex cables so
they can't be pinched between the covers and the rails.
2. On the bottom side of the N5292A, carefully fold or push down the ribbon
cables and wires so they can't be pinched between the hardware and the
outer cover. Ribbon cables and wires must never be positioned on top of
hardware.
3. Reverse the order of the removal procedures above.
