5 is displayed in the grid. Execute Peak Search and record obtained Marker Delta reading of the 4051 as
the TOI distortion lower product in B14 of the 4051 Auxiliary Form.
13) Set the center frequency of the 4051 analyzer as step up for three times. Execute Peak Search after setting
Single Sweep. The obtained Marker Delta reading of the 4051 is the TOI distortion upper product. in B14
of the 4051 Auxiliary Form.
TOI distortion (200MHz ~ 4GHz)
14) Set the frequency of synthesized signal generator#1 as 1.5 GHz, the power as+5 dBm and the RF output
as on.
15) Set the frequency of synthesized signal generator#2 as 1.50005 GHz, the signal power as -110 dBm and
the RF output as off.
16) Set the power meter frequency as 1.5GHz.
17) Reset the 4051 analyzer and set the center frequency as 1.5 GHz.
18) Repeat step 6 ~ 13.
TOI distortion (4GHz ~ 9GHz)
19) Connect the instrument as shown in Fig. 8.17 and use the MMW directional coupler to replace the RF
directional coupler in Fig. 8.16.
20) Set the frequency of synthesized signal generator#1 as 5GHz, the power as+5 dBm and the RF output as
on.
21) Set the frequency of synthesized signal generator#2 as 5.00005GHz, the signal power as -110 dBm and
the RF output as off.
22) Set the power meter frequency as 5GHz.
23) Reset the 4051 analyzer and set the center frequency as 5 GHz.
24) Repeat step 6 ~ 13.
