{PHASE LOCK}

{a2}

{REDEFINE DONE}

The b1 path signal is illustrated in Figure 5-12. Typically, each trace

±5dB).

3. Record your results in Figure 5-6.

4. To observe the b2 power level trace through path 6, press:

PARAMETER

[MENU]

{USER 2 b2}

then

{REDEFINE PARAMETER}

{DRIVE}

DRIVE:

{PORT 1}

{PHASELOCK}

{a1}

{REDEFINE DONE}

The b2 path signal is illustrated in Figure 5-12. Typically, each trace

should resemble the examples in Figure 5-12, (

±5dB).

5. Record your results in Figure 5-6.
