Operation
Port Power
Port Coupling Softkey #4 is a toggle key, alternately representing {COUPLE PORTS} or
{UNCOUPLE PORTS}. Pressing this softkey selects the displayed function, but
changes the display to show the opposite function. If you press
{COUPLE PORTS}, the Port 1 power level setting and power slope setting are
applied to Port 2. If you press
{UNCOUPLE PORTS}, the two ports have
independent power level settings and power slope settings.
Port 2 Power Functions The last three softkeys control the power level from Port 2. These softkeys
are displayed only if the ports are uncoupled.
{PORT2 POWER}, followed by a number, specifies a power level setting for
Port 2, in dBm.
{PORT2 SLOPE ON} and {PORT2 SLOPE OFF} are used to enable and disable power
slope for Port 2.
{PORT2SLOPE ON}, followed by a number, specifies the power
slope setting for Port 2, in dB/GHz.
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.
