The basic frequency is a frequency range set by the
NOTE
STIMULUS block.
Follow the steps below to set the external signal source frequency.
Step 1. Press
Step 2. Press
Step 3. Set a frequency for the external signal source by using the following softkeys:

recommended as a rule. This allows you to automatically retain the offset value even if you
have changed the setting range of the basic frequency, since the external signal source
frequency is defined as a formula. Using the

preset D.
Procedures for setting external signal source power level
Follow the steps below to set the external signal source power level.
Step 1. Press
Step 2. Press
Step 3. Press
Step 4. Set the power level.
NOTE The mixer's conversion loss and reflection coefficients are significantly affected by the
power level variation of the external signal source (LO signal). The
"External Source Menu" allows you to set a correction in dB/GHz for the power level
variation that may occur when you change the external signal source frequency.
