Suffix:
<Ch>
.
Channel number.
<Ch>
may be used to reference a previously
defined channel. If
<Ch>
does not exist, it is generated with
default channel settings.
Parameters:
<LogicalPort1>
Logical (balanced or unbalanced) port numbers. The port num-
bers must be in ascending order, their number is limited by the
test ports of the analyzer. With n logical port numbers, the com-
mand generates n
2
traces. The traces correspond to the follow-
ing S-parameters:
S
<log_port1><log_port1>
, S
<log_port1><log_port2>
... S
<log_port1><log_port<n>>
...
S
<log_port<n>><log_port1>
, S
<log_port<n>><log_port2>
... S
<log_port<n>><log_port<n>>
,
e.g. S
11
, S
12
, S
21
, S
22
for <log_port1> = 1, <log_port2> = 2. If
only one logical port <log_port1> is specified, a single trace with
the reflection coefficient S
<log_port1><log_port1>
is created.
Trace names
The generated traces are assigned the following trace names:
<Ch_name>_SG_S<log_port1><log_port1>,
<Ch_name>_SG_S<log_port1><log_port2> ...
<Ch_name>_SG_S<log_port1><log_port<n>> ...<Ch_name>_S
G_S<log_port<n>><log_port1>,
<Ch_name>_SG_S<log_port<n>><log_port2>...
<Ch_name>_SG_S<log_port<n>><log_port<n>>,
e.g. Ch1_SG_S11, Ch1_SG_S12, Ch1_SG_S21, Ch1_SG_S22
for
<Ch_name>
= Ch1, <log_port1> = 1, <log_port2> = 2. The
trace names are displayed in the "Channel Manager" and in the
"Trace Manager" dialogs where they can be changed manually.
The
<Ch_name>
is defined via
CONFigure:CHANnel<Ch>:NAME '<Ch_name>'
.
Trace names are important for referencing the generated traces;
see program example below.
