1. Connect a cable between Port 1 and Port 2.
2. To observe the b1 power-level trace through path 5, press:
PARAMETER
[MENU]
{USER 4 b1}
then
{REDEFINE PARAMETER}
{DRIVE}
DRIVE:
{PORT 2}
{PHASE LOCK}
{a2}
{REDEFINE DONE}
The b1 path signal is illustrated in Figure 5-12. Typically, each trace
should resemble the examples in Figure 5-12, (
±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.
NOTE
Be sure that you return the parameters to their original conditions for a1, b1,
a2, and b2. Use the redefine function to achieve this, or push the instrument
TEST switch to restore factory default conditions.
