10. Set the spectrum analyzer LINE switch to ON, and key in
appear on the CRT display.
11. Connect a BNC to SMB snap-on test cable and probe (SMB male
bulkhead connector) to the RF INPUT of the second spectrum
analyzer.
12. Press (2--22GHz) on the second spectrum analyzer. Set the controls
of the second spectrum analyzer as follows:
CENTER FREQUENCY . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .321.4 MHz

to SMB snap-on test cable.
In the following steps, an SMB male bulkhead connector is used as
an input probe for the second spectrum analyzer. The probe tip is
partially inserted through access holes in the bottom cover of the
one of the adjustable capacitors, false readings will result as indicated
by a sudden jump in the amplitude of the 321.4 MHz signal displayed
on the second spectrum analyzer.
14. Partially insert the probe connected to the second spectrum
analyzer into the access hole above A6A3AlC9 (the second access
