Port Power
Port Power
Port-specific power settings are made using this menu:
STIMULUS [MENU] {POWER MENU}
Figure 3-16 Power Menu & Equivalent GPIB Commands
NOTE The port power functions are valid only if {RF LEVEL / SYSTEM} is selected on
the
[SYSTEM] {MORE} {RF POWER CONFIG} menu (see “RF Power Configuration”
on page 3-30).
Port 1 Power Functions The first three softkeys control the power level from Port 1 (and also from
Port 2, if the ports are coupled).
{PORT1 POWER}, followed by a number, specifies a power level setting for
Port 1, in dBm. If the ports are coupled, this setting applies also to Port 2.
{PORT1 SLOPE ON} and {PORT1 SLOPE OFF} are used to enable and disable power
slope for Port 1.
{PORT1SLOPE ON}, followed by a number, specifies the power
slope setting for Port 1, in dB/GHz. If the ports are coupled, this setting
applies also to Port 2.
NOTE During operation in the power slope mode, the power at the first frequency
of the sweep is the current port power level; slope is applied as frequency
increases. Power slope has no effect on CW measurements.
