APPENDIX C
NOTE
For frequencies 1.3 GHz and above proceed to step (6) below.
For frequencies above 1.3 GHZ, the offset frequency should be
120.53 MHz above that of signal generator No. 1.
(5) Calculate and record the proper offset frequency and record it as the 'Offset
Frequency' in table C1 alongside the appropriate test frequency. Set signal generator No. 2
to produce a +8 dB output at offset frequency.

MHz key.
(7) Press measuring receiver RF POWER key. Verify that the RF power mode has
been properly calibrated, press Log/Lin key for a dB display, and press TI RATIO key.
(8) Set the TI to 0 dB or minimum level and connect to the TI INSERTION POINT
