Setting the matching circuit function
Add the matching circuit to PORT 4.
The matching circuit function uses the user defined circuit file.
The user defined circuit file “sfadd4.s2p” contains data to add an inductance of 150nH and
this data has been created in advance.
Reading the user defined circuit file
Insert the floppy disk containing the user defined circuit file “sfadd4.s2p” into the floppy
disk drive.
[FUNCTION]
→
{SOFTWARE FIXTURE}
→
{LOAD USR CIRCUIT}
→
{LOAD ADD S2P}
→
{LOAD sfadd4.s2p}
The user defined circuit file “sfadd4.s2p” is read from the floppy disk into the memory
of this instrument. When reading is completed, a message "a:/sfadd4.s2p: Done" is
displayed.
Selecting the matching circuit type
Set the matching circuit type to the user defined circuit to execute it.
[FUNCTION]
→
{SOFTWARE FIXTURE}
→
{PORT CONDITION}
→
{ADD CIRCUIT}
→
{More 1/4}
→
{More 2/4}
→
{More 3/4}
→
{PORT4 ADD TYPE[ ]}
→
{PORT4 USR CIRCUIT}
Executing the matching circuit function
Execute the matching circuit function.
{Return}
→
{PORT4 ADD CIRCUIT ON}
When this matching circuit is added, the network actually gets out of balance and the
waveform is greatly deformed.
