(1) Refer to Results table 5-45 on page 5-51. Set the UUT to [Tx TEST], [SELECT] N-type
input socket (i.e. only the K LED on). From power up, the instrument should already be set
to Autotune mode with wide band power meter (WB) selected.
(2) Connect the equipment as shown in Fig 5-19, connecting to the N-type input socket on the
UUT.
(3) Set the calibrated power source to provide a signal at 11 MHz and 100 mW(+20 dBm) to the
UUT input. Note the level on the UUT broad band power meter and check that it is within
the stated specification. Repeat at 100 MHz and then in 100 MHz steps up to and including
1000 MHz.
